Dinosaurs of a Feather 2017-12-29T05:00:00Z Ms. dePolo plans to explore the Isle of Skye for more sauropod and theropod footprints. In Footprints on Scotland’s Isle of Skye, Signs of a Dinosaur Playground 2018-04-04T04:00:00Z Other dinosaurs crowded the setting: A long-necked sauropod squelched through the muck, while several theropods — smaller cousins of the fearsome T-rex — stalked the landscape. Spectacular dinosaur stomping grounds discovered just outside D.C. 2018-01-31T05:00:00Z There are also tracks of four theropods — relatives of the Tyrannosaurus rex that lived tens of millions of years later, but these were smaller, roughly the size of a large raven. Where NASA Put a Parking Lot, Dinosaurs and Mammals Once Crossed Paths 2018-01-31T05:00:00Z But there is at least one other fossil that indicates theropods really were scurrying around Triassic Utah. Where Are Utah's Triassic Dinosaurs? 2018-01-07T05:00:00Z And who were the large theropods around at this time? Dinosaurs of a Feather 2017-12-29T05:00:00Z The theropods were only about three feet at the hip, she said. In Footprints on Scotland’s Isle of Skye, Signs of a Dinosaur Playground 2018-04-04T04:00:00Z Looking with him, Tucker pointed out how the size, shape and spacing of the theropod tracks looked almost synchronized. Spectacular dinosaur stomping grounds discovered just outside D.C. 2018-01-31T05:00:00Z Palaeontologists first discovered the imprint of the theropod dinosaur in a tidal rock platform in Flat Rocks, Victoria in 2006. Dinosaur footprint vandalised in Australia 2017-12-20T05:00:00Z The best record of Triassic dinosaurs in Utah, Jenkins and coauthors point out early in their paper, is likely to be a bonebed of small theropods found just outside Dinosaur National Monument. Where Are Utah's Triassic Dinosaurs? 2018-01-07T05:00:00Z Fossilised remains of two-legged dinosaurs called theropods show that many were covered with rich feather plumages, for warmth and display. Meet Dracula, the bloodsucking tick which feasted on dinosaurs 99m years ago 2017-12-12T05:00:00Z A huge quantity of evidence shows that birds are dinosaurs, and specifically a lineage of the coelurosaurian theropod group Maniraptora. The "Birds Are Not Dinosaurs" Movement 2017-11-23T05:00:00Z Sinosauropteryx was a theropod dinosaur — in the same group as its massive cousin Tyrannosaurus, but much smaller. Stripes? Spots? Melanin pigment brings out new theories about dinosaurs 2017-11-03T04:00:00Z “But it will be nice to see if it holds up with more specimens of Sinosauropteryx and across other theropods,” he says. Camouflage plumage patterns offer clue to dinosaur’s habitat 2017-10-25T04:00:00Z “But it will be nice to see if it holds up with more specimens of Sinosauropteryx and across other theropods,” he says. Camouflage Plumage Patterns Offer Clue to Dinosaur's Habitat 2017-10-26T04:00:00Z The scientists concluded it was a large theropod -- the two-legged carnivorous dinosaur group that included later giants like Tyrannosaurus and Giganotosaurus -- but that it was more lightly built than those brutes. Fossil footprints reveal existence of big early dinosaur predator 2017-10-26T04:00:00Z The theropod hypothesis of bird origins is not universally accepted. The "Birds Are Not Dinosaurs" Movement 2017-11-23T05:00:00Z On an evolutionary scale, this transition happened until theropods developed mouths that resembled the bird beaks seen today. How dinosaurs swapped terrifying teeth for bird beaks 2017-09-29T04:00:00Z Some paleontologists have argued that theropod dinosaurs, which included the ancestors of modern birds, had open nests with partially exposed clutches, Varricchio says. Dinosaurs Laid Blue Eggs—And That's a Big Deal 2017-09-18T04:00:00Z “The plumage is composed of four wings, as with many theropod dinosaurs from China, but it did not allow ‘Silky’ to take off from the ground or from a tree.” New Feathered Dinosaur Had Four Wings but Couldn't Fly 2017-08-28T04:00:00Z The scientists concluded it was a large theropod -- the two-legged carnivorous dinosaur group that included later giants like Tyrannosaurus and Giganotosaurus -- but that it was more lightly built than those brutes. Fossil footprints reveal existence of big early dinosaur predator 2017-10-26T04:00:00Z While some details of maniraptoran phylogenies may prove incorrect, the “birds are not theropods” movement is based on erroneous argumentation and fails to account for the data as well as the theropod hypothesis does. The "Birds Are Not Dinosaurs" Movement 2017-11-23T05:00:00Z It lived about 150m years ago, far earlier than the handful of theropods known to have turned away from meat, he pointed out. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z When scientists said in 2015 they had found a plant-eating theropod dinosaur, it was as if a vegetarian had crashed a meat lovers’ barbecue. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z That such a large creature needed camouflage indicates the presence of even larger, keen-eyed meat-eating theropod dinosaurs. Armoured tank-like dino used camouflage to hide - BBC News 2017-08-03T04:00:00Z There are other fossilized footprints from Poland that indicate a similar-sized theropod inhabited the northern super-continent of Laurasia around the same time. Fossil footprints reveal existence of big early dinosaur predator 2017-10-26T04:00:00Z But no more: we now have large numbers of Cretaceous lizards in amber, a partial tail from a small non-bird theropod, and assorted archaic birds, including the better part of a baby enantiornithine. Fossils We Want To Find 2017-07-23T04:00:00Z “We realised that it was not a strange, early plant-eating theropod, but rather a strange plant-eating animal that was an offshoot of this other group, ornithischia,” Barrett said. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z Almost all theropods—the group of fierce predators that included Tyrannosaurus rex—were hypercarnivorous, eating a diet of more than 70% meat. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z And given that we can’t watch the “great lizard” or any other meat-eating theropod go about its work, the sentiment has stuck even after being stripped of its theological trappings. Nothing but the Tooth 2017-07-15T04:00:00Z There are other fossilized footprints from Poland that indicate a similar-sized theropod inhabited the northern super-continent of Laurasia around the same time. Fossil footprints reveal existence of big early dinosaur predator 2017-10-26T04:00:00Z But Therizinosaurus is a giant, potentially one of the biggest theropods of all. Fossils We Want To Find 2017-07-23T04:00:00Z “Chilesaurus initially looked like an earlier offshoot of the theropod line, but it seemed suspicious that it had all these adaptations for eating plants,” Barrett said. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z After numerous statistical analyses, Novas and his team concluded that the animal was probably a theropod. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z But suppose that Ceratosaurus, Carcharodontosaurus, or any of the other hulking, sharp-toothed theropods tried some larger fare. Nothing but the Tooth 2017-07-15T04:00:00Z While it is not clear how the dinosaur died, Jordan said there are tantalising clues, including evidence of bite marks and healing from the bones, and the discovery of theropod footprints in the rocks. Rare dinosaur remains discovered under Surrey brick factory 2017-07-04T04:00:00Z Tyrannosaurs belonged to a greater group of theropod dinosaurs called coelurosaurs. Long Live the Fuzzy T. rex 2017-07-01T04:00:00Z But the Chilesaurus shows that the fearsome killers under the theropod umbrella shared, in fact, a greater affinity with the docile ornithischia menagerie. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z The theropodlike features, they suggest, actually lend support to their original hypothesis: that theropods and ornithischians are more closely related than previously thought. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z Yes, yes, we all ridicule the little, two-clawed nubs of Tyrannosaurus, but it was actually the forelimbs of Allosaurus and similarly-equipped theropods that make little sense. Nothing but the Tooth 2017-07-15T04:00:00Z White and colleagues conclude that the large Lark Quarry trackway was probably created by a theropod similar to Australovenator, after all. Walking with Australovenator 2017-06-10T04:00:00Z Other theropod dinosaurs, like the comparatively small Juravenator, have already shown such arrangements. Long Live the Fuzzy T. rex 2017-07-01T04:00:00Z The new findings support the idea that theropods and ornithischians shared a common ancestor as early as 225m years ago. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z If their reclassification is correct, there would also be one less theropod that went vegetarian—an unusual transition. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z Large carnivorous theropods probably had a preference for young victims. Nothing but the Tooth 2017-07-15T04:00:00Z The theropod family included tyrannosaurus, two-legged dinosaurs and some bird ancestors. The “Jurassic Park” T-Rex of your nightmares is back 2017-06-09T04:00:00Z The find was reported by several of the same researchers who discovered a feathered theropod dinosaur tail preserved in amber last December. Baby Bird from Time of Dinosaurs Found Fossilized in Amber 2017-06-07T04:00:00Z Most theropods were wiped out too, although the forerunners of modern birds persevered. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z Even if Chilesaurus itself isn’t a theropod, scientists still have a handful of other theropods that have “gone green” to puzzle over, such as the therizinosaurs and another oddball called Limusaurus. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z If one thing is for certain, it is that this will not be the end of the fluffy theropod debate. Feather furore: T.rex may not have been fluffy after all, skin study suggests | Susannah Lydon 2017-06-07T04:00:00Z If herrerasaurids only look like theropods, but are actually distant relatives, that means hypercarnivorous dinosaurs evolved at least twice near the root of the family tree. Shaking the Dinosaur Family Tree 2017-05-28T04:00:00Z No one has found the skeleton of a tyrannosaur that died while dreaming, but rare skeletons and fossilised impressions indicate that theropod dinosaurs – the wider family to which tyrannosaurs belonged – dozed much like modern birds. Bloodthirsty chomp-monster or sensitive lover? Time to rethink Tyrannosaurus rex | Brian Switek 2017-04-03T04:00:00Z An upright posture, powerful hind legs and foreshortened front limbs were all reminiscent of theropods. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z Novas, for his part, isn’t convinced that Baron and Barrett have the right answer, stating that their interpretation overlooks the many features Chilesaurus shares with theropods. Scientists struggle to fit this strange vegetarian dinosaur into the family tree 2017-08-15T04:00:00Z Just look at the recent debate around the lack of feathers on the GM theropods in Jurassic World. Feather furore: T.rex may not have been fluffy after all, skin study suggests | Susannah Lydon 2017-06-07T04:00:00Z The saurischian dinosaurs included only theropods and sauropods, further united by pneumatic – or hollow – bones. Shaking the Dinosaur Family Tree 2017-05-28T04:00:00Z The so-called reptile-hipped Saurischia covered theropods including birds and the sauropods. Revolutionary overhaul of dinosaur family tree proposed 2017-03-22T04:00:00Z For most of the last century, experts have agreed that theropods were more closely related to a third major evolutionary branch, the sauropods, that included long-necked beasts such as Diplodocus and Brachiosaurus. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z Their research moves the theropods such as T. Rex to a new branch of the family tree and hints at an earlier and more northern origin for dinosaurs. New idea shakes up dinosaur family tree for T. Rex and pals 2017-03-22T04:00:00Z As it happens, Thomas Huxley, the celebrated 19th century champion of Darwin’s theory of evolution, also thought Ornithischia and theropods belonged together in the same group, which he called Ornithoscelida. Shaking Up the Dinosaur Family Tree 2017-03-22T04:00:00Z After analyzing 457 skeletal characteristics in 74 taxa, Baron and coauthors concluded that theropods and sauropods are not each other’s closest relatives, after all. Shaking the Dinosaur Family Tree 2017-05-28T04:00:00Z The first, called Ornithoscelida, joins the theropods with all the current members of Ornithischia. Revolutionary overhaul of dinosaur family tree proposed 2017-03-22T04:00:00Z “Our reorganisation was putting ornithischia and theropods much closer together, and this new animal helps cement that relationship,” Barrett explained. 'Most bizarre dinosaur ever found' is missing evolutionary link – study 2017-08-16T04:00:00Z And no one knew where to put the herrerasaurids—early, carnivorous dinosaurs that look a little like theropods and a little like sauropods. T. rex gets new home in shakeup of dino family tree 2017-03-22T04:00:00Z The Saurischian branch includes both sauropods like the herbivorous diplodocus, and theropods like the meat-eating tyrannosaurs. Shaking Up the Dinosaur Family Tree 2017-03-22T04:00:00Z The results, published in Nature, suggest that theropods should be switched over to become an off-shoot of the same branch that led to stegosaurus and triceratops. Radical shakeup of dinosaur family tree points to unexpected Scottish origins 2017-03-22T04:00:00Z The new approach argues for the meat-eaters, a group known as theropods, to be moved into the same classification as the bird-hipped dinosaurs. Major shake-up suggests dinosaurs may have 'UK origin' - BBC News 2017-03-22T04:00:00Z Last but not least, they threw in the Dinosaur Kingdom, a sprawling Triassic theme park where Chinese tourists will soon be able to gaze at super-sized models of flesh-eating theropods. China goes west: a ghost city in the sand comes to life 2017-03-21T04:00:00Z The feathers most likely belonged to a baby nonavian theropod, meaning it looked more similar to a velociraptor or Tyrannosaurus rex than to a modern bird. That Thing With Feathers Trapped in Amber? It Was a Dinosaur Tail 2016-12-08T05:00:00Z But it’s the other group, the theropods—which includes Tyrannosaurus rex and Velociraptor—that are the closer cousins and ancestors of birds. Dinosaur babies took a long time to break out of their shells 2017-01-02T05:00:00Z Unlike better known theropods like velociraptors, “this guy was not a traditional meat eater,” Dr. Brusatte said. A Dinosaur With a Beak and Feathers Unearthed in China 2016-11-10T05:00:00Z Last year, his team used chemicals to modify development pathways in chickens that they thought helped to mould the snouts of theropod dinosaurs into modern birds’ beaks. CRISPR's hopeful monsters: gene-editing storms evo-devo labs 2016-08-16T04:00:00Z For the record, T. rex is one of the largest theropods - that means beast-footed - that ever existed. University team hunting T. rex backed by crowdfunding 2016-07-22T04:00:00Z He added that because the feathers were found with the vertebrae, there was no question they belonged to a nonavian theropod dinosaur as opposed to a prehistoric bird. That Thing With Feathers Trapped in Amber? It Was a Dinosaur Tail 2016-12-08T05:00:00Z “What would be really interesting now is to see if small theropod dinosaurs like Velociraptor also incubated slowly,” Brusatte says. Dinosaur babies took a long time to break out of their shells 2017-01-02T05:00:00Z Oviraptorosaurs are not direct ancestors of birds, but share a common theropod dinosaur ancestor with the lineage that later evolved to birds. A Dinosaur With a Beak and Feathers Unearthed in China 2016-11-10T05:00:00Z It was an upright, birdlike theropod like the T. rex, but the two were extremely distant cousins. T. rex wasn’t the only dinosaur to evolve pitifully puny arms 2016-07-14T04:00:00Z This is one of the few theropods with miniature arms, and scientists are hoping the new discovery could help them determine the evolutionary causes of these small limbs. This New Dinosaur Had Tiny Arms Just Like T-Rex 2016-07-14T04:00:00Z The position of Gualicho on the theropod tree suggests it evolved its small forelimbs independently from other carnivorous dinosaurs which shared the trait - rather than it arising from a common ancestor. Predatory dinosaur had tiny arms like Tyrannosaurus rex - BBC News 2016-07-14T04:00:00Z “But obviously there was some adaptive advantage because we see it multiple times in different lineages of theropods” New Dinosaur and T. Rex Were Brothers in Tiny Arms 2016-07-13T04:00:00Z Gualicho and other carnivorous dinosaurs like Tyrannosaurus rex are part of a group called theropods that included Earth's largest-ever land predators. Fearsome Argentine dinosaur had pitifully puny arms 2016-07-13T04:00:00Z As scientists uncover more theropods that bore puny arms, they might be able to pinpoint minute differences in limb and hand formation that show the evolutionary pressures behind each individual case of the adaptation. T. rex wasn’t the only dinosaur to evolve pitifully puny arms 2016-07-14T04:00:00Z The current museum housed in Ms. Brammall’s office — where just 5 percent of the collection is displayed — holds delicate, minuscule and beautifully detailed opalized pine cones, a theropod dinosaur’s tooth and ancient lungfish toothplates. An Australian Town’s Rare Mix: Dinosaur Bones and Opalized Pine Cones 2016-07-05T04:00:00Z Small theropods such as velociraptors are already often depicted with lips. Tyrannosaurus rouge: lips may have hidden T rex's fierce teeth 2016-05-21T04:00:00Z The new dinosaur belonged to a different type of theropods called the allosaurs, which usually had strong, proportionally sized arms. New Dinosaur and T. Rex Were Brothers in Tiny Arms 2016-07-13T04:00:00Z Specifically, a group of two-legged carnivorous dinosaurs called theropods seems to have evaded the great dino extinction event 65 million years ago by developing feathers, bigger and more adaptable brains, and smaller, more airborne forms. Finally, You Can See Dinosaurs in All Their Feathered Glory Why has it taken so long to recognize that Huxley had almost certainly been right about the origin of birds from some meat-eating theropod dinosaurs? ‘Dinosaurs Among Us’ Retraces an Evolutionary Path 2016-03-28T04:00:00Z By measuring the size of the tracks and distance between them Persons verified that they were made by a large theropod, like a tyrannosaur, about 66 million years ago. Wyoming dinosaur footprint officially measured 2016-03-08T05:00:00Z It’s just the larger theropods, such as the T rex, who are almost always shown with their teeth exposed. Tyrannosaurus rouge: lips may have hidden T rex's fierce teeth 2016-05-21T04:00:00Z “We know they had feathers and crests and good vision,” Lockley said, speaking of theropods, the carnivore family of Tyrannosaurs rex. Dinosaurs performed dances to woo mates, according to new evidence 2016-01-07T05:00:00Z Dinosaur expert Thomas Holtz Jr. of the University of Maryland, who didn’t participate in the work, said it’s reasonable to think that theropods created the grooves. In the groove: Scrape marks in ground linked to dinosaurs 2016-01-07T05:00:00Z Dinosaur expert Thomas Holtz Jr. of the University of Maryland, who didn't participate in the work, said it's reasonable to think that theropods created the grooves. Scientists who found long grooves in the ground in Colorado suggest they were dug by dinosaurs during a frenzied ritual to attract mates 2016-01-07T05:00:00Z Describing the theropod tracks fit in well with Persons’ doctoral thesis examining how dinosaurs walked and ran.

Tyrannosaurus rouge: lips may have hidden T rex's fierce teeth 2016-05-21T04:00:00Z But he noted that fossils can reveal some certainties – for instance what ancient animals ate, how they nested and herded – and said comparing theropod behavior to birds’ was a persuasive method. Dinosaurs performed dances to woo mates, according to new evidence 2016-01-07T05:00:00Z For this reason, some at the site speculated that the tracks might be a game trail: theropods stalking their sauropod prey. Amateur Sleuths on the Dinosaur Trail 2016-01-04T05:00:00Z But some of the dinosaur species in one group—a subset of well-evolved theropods considered to be the closest relatives of modern-day birds—laid low-porosity eggs, which suggests they incubated their eggs in open nests. Missing link between dinosaur nests and bird nests 2015-11-25T05:00:00Z We also report a set of new theropod remains. Late Cretaceous Animals of Romania's Haţeg Island, A More Complex View 2015-09-28T04:00:00Z "In theropods, the serrations are larger and deeper than the superficial view suggests, making them stronger and longer lasting, less likely to get damaged or worn," University of Toronto Mississauga paleontology professor Robert Reisz said. Toothy terror: dinosaurs like T. rex had unique serrated teeth 2015-07-28T04:00:00Z It’s a bird, but that’s not actually a big deal. We incorporated Balaur into an updated version of Andrea’s giant, evolving theropod matrix – the one we previously used in our Lee et al. The Romanian Dinosaur Balaur Seems to be a Flightless Bird 2015-06-20T04:00:00Z We now know that species like Velociraptor and Gallimimus would have had feathers, and this would likely have been true for other theropods as well, including Tyrannosaurus. Awesome Dinos, Iffy Science Inhabit "Jurassic World" 2015-06-18T04:00:00Z In research published in Current Biology last fall, Stephen Brusatte, a paleontologist at the University of Edinburgh in Scotland, and collaborators examined fossils from coelurosaurs, the subgroup of theropods that produced archaeopteryx and modern birds. How Dinosaurs Shrank and Became Birds 2015-06-12T04:00:00Z Incidentally, there is as yet no indication whatsoever of large theropods in the Haţeg Island assemblage. Late Cretaceous Animals of Romania's Haţeg Island, A More Complex View 2015-09-28T04:00:00Z The study involving eight theropod species revealed their previously unknown tooth complexity. Toothy terror: dinosaurs like T. rex had unique serrated teeth 2015-07-28T04:00:00Z Paravian theropods are all the rage right now, and not just because of the phylotarded, retrofitted ones that appear in a certain blockbuster movie. The Romanian Dinosaur Balaur Seems to be a Flightless Bird 2015-06-20T04:00:00Z Non-theropod dinosaurs showed up quite a bit in this movie, but unfortunately they usually just served as food for the rampaging theropod hybrid. A Paleontologist Reviews 'Jurassic World' 2015-06-12T04:00:00Z Modern birds descended from a group of two-legged dinosaurs known as theropods, whose members include the towering Tyrannosaurus rex and the smaller velociraptors. How Dinosaurs Shrank and Became Birds 2015-06-12T04:00:00Z A really weird thing about several of the Haţeg Island theropods is that the outside surfaces of their bones possess a distinctive ‘wrinkled’ texture that consists of subparallel, raised ridges.

The Romanian Dinosaur Balaur Seems to be a Flightless Bird 2015-06-20T04:00:00Z The theropod is the first meat-eating dinosaur fossil to be found in Wales and is one of the oldest finds from the Jurassic Period in the world. Wales' 'first meat-eating' Jurassic dinosaur on show - BBC News 2015-06-09T04:00:00Z Although, interestingly, recent research does suggest the common ancestor of dinosaurs was not feathered and the ‘feathery’ coating seen in ornithischian dinosaurs arose independently from the feathers of theropods. Jurassic World and The Cinematic Science of Dinosaurs 2015-06-08T04:00:00Z Indeed, another interesting thing about the taxa concerned is that they’ve been re-interpreted on several occasions as the members of different theropod groups. Late Cretaceous Animals of Romania's Haţeg Island, A More Complex View 2015-09-28T04:00:00Z "We are pretty convinced that Chilesaurus is an early theropod, but other scientists may dispute that conclusion," Vargas says. This animal is so weird that researchers are calling it "the platypus of dinosaurs" 2015-04-27T04:00:00Z Evidence from both genetics and fossils proves that modern birds are descended from the theropods, a category of two-legged dinosaurs that includes Tyrannosaurus rex, some of which survived the extinction.

The beast with the behemoth arms: A dinosaur mystery is solved 2014-10-22T04:00:00Z This means that a plant-based diet was acquired by theropods — the group of dinosaurs to which both T. rex and Chilesaurus belong — far earlier than originally thought. This animal is so weird that researchers are calling it "the platypus of dinosaurs" 2015-04-27T04:00:00Z Their general size and shape mark the creature as a theropod, a bipedal meat eater. New meat-eating dinosaur lived in the wake of a mass extinction 2014-10-07T04:00:00Z The conclusion is that there is no missing link between theropods, the bipedal carnivorous dinosaurs that included T rex and Velociraptors, and avialans, the sub-group that includes birds. Burst Of Evolution As Birds Took Wing 2014-09-25T04:00:00Z It measured so large, it faced little threat from predators, which instead apparently scavenged Dreadnoughtus meat only after the animal died – teeth from smaller theropod predators were found near the dig site. Scientists Discover Colossal 'Dreadnoughtus' Dinosaur 2014-09-04T04:00:00Z Starting from an average mass of 163 kilograms, the theropod suborder eventually produced the .8 kilogram Archaeopteryx, which is considered the earliest bird. Which dinosaurs survived? The ones that shrank the fastest. The researchers found theropods were the only dinosaurs to get continuously smaller. Dinosaurs 'shrank' to become birds 2014-07-31T04:00:00Z The bones differ enough from those of other theropods to indicate that the dino is a new species, Langer and his colleagues report today in Royal Society Open Science. New meat-eating dinosaur lived in the wake of a mass extinction 2014-10-07T04:00:00Z He finds that the two-legged, primarily meat-eating dinosaurs known as theropods were also declining. Dinosaur-killing asteroid hit at just the wrong time 2014-07-27T04:00:00Z Meat-eating dinosaurs such as Tyrannosaurus rex and Velociraptor were all reptiles known as theropods; they relied on sharp teeth and claws to capture and kill prey. Herbivorous Theropod Dinosaurs Had Sharp Claws, Too 2014-05-07T20:28:00Z Obviously we have so many feathery theropods now they’ve even been described as mundane, plus now there are even filamentous structures on ornithischians. Speculative Zoologists Imagine Beasts of the Future 2014-04-04T11:06:16Z The authors used sophisticated analytical tools - developed by molecular biologists trying to understand virus evolution - to study more than 1,500 dinosaur body traits coded from 120 well-documented species of theropod and early birds. Dinosaurs 'shrank' to become birds 2014-07-31T04:00:00Z “All the small dinosaurs of that era looked about the same,” he notes, but subtle skeletal differences help distinguish the carnivorous theropods from their herbivorous and omnivorous relatives. New meat-eating dinosaur lived in the wake of a mass extinction 2014-10-07T04:00:00Z The sauropod and theropod prints comprise one of the most famous sequences from the site. Dinosaur Tracks Reconstructed in 3D From Old Photographs 2014-04-03T17:47:00Z This suggests changes in theropod diet were major drivers for skeletal changes in theropod evolution. Herbivorous Theropod Dinosaurs Had Sharp Claws, Too 2014-05-07T20:28:00Z Dougal has made several large-scale models of theropods and other animals. Speculative Zoologists Imagine Beasts of the Future 2014-04-04T11:06:16Z The tracks are from two dinosaurs, a large, herbivorous sauropod, and a carnivorous theropod - the group of top predators to which Tyrannosaurus rex belonged. Dinosaur chase scene reconstructed 2014-04-02T23:43:41Z It was a theropod - the kind of two-legged, meat-eating animal that everyone instantly recognises in something like Tyrannosaurus rex. Ferocious dino was European giant 2014-03-05T22:03:02Z Coming after it — perhaps hours or days later, or perhaps hot on its tail in a dinosaur chase scene — a meat-eating theropod followed, overlaying some of the sauropod's footprints with its own. Dinosaur Tracks Reconstructed in 3D From Old Photographs 2014-04-03T17:47:00Z Lautenschlager investigated an unusual group of theropods known as therizinosaurs, which lived between 66 million and 145 million years ago in Asia and North America. Herbivorous Theropod Dinosaurs Had Sharp Claws, Too 2014-05-07T20:28:00Z The klutzy dinosaur was a theropod, according to research presented Oct. Dinosaur's Klutz Moment Preserved in Time 2013-11-05T23:15:02.027Z “Tyrannosaurids used their arms in the same way all theropods used their arms, for grasping and stabilizing objects” — namely prey, he says. Palaeontology: The truth about T. rex 2013-10-23T17:20:31Z Five years ago, a study of theropod dinosaurs concluded that it was male dinosaurs that incubated the eggs of their offspring. Dinosaur dads may not have been very caring after all 2013-05-27T19:52:56Z It might be tempting to suggest that the presence on Haţeg Island of these different azhdarchid species is linked in some way to this absence of large theropods. A new azhdarchid pterosaur: the view from Europe becomes ever more interesting 2013-01-31T14:15:08.667Z These findings might shed light on the evolution of modern birds from ancient theropods. Herbivorous Theropod Dinosaurs Had Sharp Claws, Too 2014-05-07T20:28:00Z With all of this in mind, we included claw data from various Mesozoic birds and other theropods in our analysis. Did Velociraptor and Archaeopteryx climb trees? Claws and climbing in birds and other dinosaurs 2012-12-18T12:45:00.183Z This photo released by the Bureau of Land Management shows tracks made by a grallator, a small theropod - a two-legged, three-toed, meat-eating dinosaur - in the Red Rock Canyon National Conservation Area in Nevada. Dinosaurs! 2012-12-05T06:00:20Z This revealed that nesting theropod dinosaurs produced unusually large clutches for their body mass, a pattern often seen in birds in which the male alone cares for the eggs. Dinosaur dads may not have been very caring after all 2013-05-27T19:52:56Z In the autonomous region of Inner Mongolia, the Xu group found a new type of bird and what may be a previously unknown theropod — the dinosaur lineage that led to birds. China's dinosaur hunter: The ground breaker 2012-09-05T17:20:32.287Z "The stereotypical image of theropod dinosaurs is that of large, predatory and carnivorous animals," said study author Stephan Lautenschlager, a vertebrate paleontologist at the University of Bristol in England. Herbivorous Theropod Dinosaurs Had Sharp Claws, Too 2014-05-07T20:28:00Z They mostly concluded that birds and other theropods did not possess the anatomical features expected for a climbing lifestyle. Did Velociraptor and Archaeopteryx climb trees? Claws and climbing in birds and other dinosaurs 2012-12-18T12:45:00.183Z As a strong proponent of the well supported inclusion of birds within the theropod dinosaur radiation, I’m personally more than happy to see people referring to birds as ‘living dinosaurs’. Dyke & Kaiser s Living Dinosaurs: the Evolutionary History of Modern Birds 2012-08-27T00:45:02.620Z It is increasingly realised that many of the 'hair-like', 'stage 1' feathers of non-bird theropods are actually the degraded or misinterpreted versions of more complex feathers. The war on parasites: the pigeon's eye view, the oviraptorosaur's eye view 2012-08-23T14:45:02.890Z The smart, quick theropod dinosaurs that gave rise to birds may have had feathers, but they did not fly and they certainly didn’t resemble birds today. Side Effects: Skull Analysis Charts the Changes From Dinosaurs to Birds 2012-06-01T03:31:49Z Minute theropod eggs and embryo from the Lower Cretaceous of Thailand and the dinosaur-bird transition. A drowned nesting colony of Late Cretaceous birds 2012-05-15T16:15:03.013Z Climbing, perching and ground-running Mesozoic birds and other theropods Flexion in the foot of Deinonychus as reconstructed by Fowler et al. Did Velociraptor and Archaeopteryx climb trees? Claws and climbing in birds and other dinosaurs 2012-12-18T12:45:00.183Z During the Jurassic and Cretaceous there were several lineages of small, feathered maniraptoran theropods - birds were not 'special' or especially 'different' at this time. Dyke & Kaiser s Living Dinosaurs: the Evolutionary History of Modern Birds 2012-08-27T00:45:02.620Z But I don’t think anyone’s really married data on Mesozoic birds and other theropods with the new work of Dale Clayton and colleagues on ectoparasite control in extant birds. The war on parasites: the pigeon's eye view, the oviraptorosaur's eye view 2012-08-23T14:45:02.890Z To test the idea, the group used CT scan information on all the known fossils of theropod dinosaurs that show skull growth, as well as skulls of birds and crocodilians. Side Effects: Skull Analysis Charts the Changes From Dinosaurs to Birds 2012-06-01T03:31:49Z Like modern birds, and like their close relatives among the theropod dinosaurs, the birds of the Mesozoic Era laid eggs and, we reasonably infer, made nests. A drowned nesting colony of Late Cretaceous birds 2012-05-15T16:15:03.013Z Known from three well-preserved specimens, it’s yet another feathered theropod dinosaur from the Lower Cretaceous Yixian Formation of Liaoning Province, China. There are giant feathered tyrannosaurs now... right? 2012-04-05T11:45:00.167Z Horns, hornlets, bosses, twin ridges and other structures decorate the skulls of various ornithischians and Mesozoic theropods, various pterosaurs possess sail-like crests, there are the thick skull domes of pachycephalosaurs, and so on. Did dinosaurs and pterosaurs practise mutual sexual selection? 2012-01-05T15:45:07.957Z Instead of theropod footmarks, they found those of crocodilians. What ate dinosaurs?: Old crocs 2011-11-09T18:02:58Z That was a tibia from a theropod, the two-legged carnivore typified by Tyrannosaurus rex. Dinosaur hunters make curious find in Prince George?s County 2011-09-22T00:50:13Z Given that this was confused with a theropod I’m guessing these were calcite eggs. A drowned nesting colony of Late Cretaceous birds 2012-05-15T16:15:03.013Z I like the connection to ecological dominance relationships with other large theropods. There are giant feathered tyrannosaurs now... right? 2012-04-05T11:45:00.167Z For those interested I have posted a couple more on some of the details of the paper: See this article on crest size in theropods and this one on theropod sociality. Did dinosaurs and pterosaurs practise mutual sexual selection? 2012-01-05T15:45:07.957Z But that does not completely explain the absence of theropod tracks. What ate dinosaurs?: Old crocs 2011-11-09T18:02:58Z But Hacker is convinced that this fossil is not a theropod. Dinosaur hunters make curious find in Prince George?s County 2011-09-22T00:50:13Z The collaboration focuses on dinosaur reproductive biology and understanding the evolution of reproductive traits in the transition from small carnivorous theropod dinosaurs to modern birds. New Expedition - MSU student research with dinosaur eggs in China 2011-06-16T14:45:00.537Z The tracks were made by multiple species of sauropod, theropod and ornithopod dinosaurs as they walked across mud flats around 130 million years ago. Dinosaur Footprints Threatened by Natural Gas Project 2011-05-11T19:45:00.457Z There are hundreds of footprints on the beach at Brook Bay but it's extraordinary to find three in one, and the little theropod print is unique. Isle of Wight fossil is footprint triple play 2011-04-11T12:33:49Z Tyrannosaurines are a specialised group of gigantic theropods - a group of dinosaurs that likely evolved into modern birds. Giant cousin of T. rex identified 2011-03-31T14:54:25Z It is part of the Alvarezsauroidea family of theropods, a group of small, long-legged dinosaurs, known for their strange and tiny arms. Two-clawed T.rex cousin found 2011-01-25T01:24:18Z It is part of the Alvarezsauroidia family of theropods, a strange group of small, long-legged running dinosaurs. Two-clawed T.rex cousin found 2011-01-25T01:24:18Z The uni-clawed theropod was not actually a big surprise to the scientists who described it. Digital reduction: Newly described dinosaur had only one finger per stubby forelimb 2011-01-24T23:45:00.247Z The fossil remains of Eodromaeus show features in the skull, forelimbs, hindlimbs and pelvic girdle that link it to the theropods, the group dominated by meat-eaters such as Tyrannosaurus rex and Velociraptor mongoliensis. Move over Eoraptor: Dinosaur is recast as plant-eater 2011-01-14T00:45:00.463Z Based on its anatomy, Dr. Sereno and his colleagues believe it was an early ancestor of other theropod dinosaurs, a group that includes Tyrannosaurus rex. Observatory: Pet-Size Dinosaur Was Early Ancestor to T. Rex, Researchers Say 2011-01-13T22:53:01Z "Alvarezsauroids are already known to be an unusual group of theropods with very bizarre hands used primarily for digging, and this new find confirms there was some variation in how weird these hands were." Two-clawed T.rex cousin found 2011-01-25T01:24:18Z The suggestion is that this mono-digit theropod may represent the end of one evolutionary pathway, in which unused digits disappear as part of a process of natural selection. Two-clawed T.rex cousin found 2011-01-25T01:24:18Z The diminutive, two-meter-long Tawa hallae fills a big gap in the fossil record between the earliest carnivores, such as Herrerasaurus, and later theropod lines that include Tyrannosaurus rex and the first birds. Newly Discovered T. Rex Relative Fleshes Out Early Dino Evolution 2011-01-10T07:45:48.450Z All of these features were inherited by later theropods. Move over Eoraptor: Dinosaur is recast as plant-eater 2011-01-14T00:45:00.463Z The one-day-old Australian brush turkey, he says, may behave as theropods once did. Flying Machines, Amazing at Any Angle 2011-01-03T22:56:34Z Scientists at the Field Museum in Chicago report their findings on theropod dinosaurs in the Proceedings of the National Academy of Sciences. Observatory: T. Rex?s Relatives Had More Items on Their Menu 2010-12-21T01:05:08Z The New Mexico fossil beds included several other theropods that the scientists found were more closely related to different groups of South American theropods than to each other. Observatory: Bones Show Early Divergence of Dinosaur Lineage 2009-12-15T19:58:00Z It provides a much clearer picture of the basal theropods, Norell says. Newly Discovered T. Rex Relative Fleshes Out Early Dino Evolution 2011-01-10T07:45:48.450Z In most ways, the dinosaur is not unusual, and it shares many characteristics with other medium-size theropods. Observatory: A Humpbacked Dinosaur Has a Unique Story to Tell 2010-09-14T04:43:00Z Evidence of feeding by theropod dinosaurs, such as Velociraptor or Tyrannosaurus rex , are scarce in the fossil record and the fighting dinosaurs is the most dramatic example known potentially illustrating such behaviour. Velociraptor 'caught' eating dino 2010-04-06T07:09:00Z “Our image of theropods as flesh eaters is antiquated and outdated,” said Lindsay Zanno, a paleontologist at the museum and the study’s lead author. Observatory: T. Rex?s Relatives Had More Items on Their Menu 2010-12-21T01:05:08Z That suggests theropods diverged and radiated from South America. Observatory: Bones Show Early Divergence of Dinosaur Lineage 2009-12-15T19:58:00Z It is the first dinosaur of its type, known as an alvarezsaurid theropod, found in China, with just tiny fragments of its relatives previously being found further north in Inner Mongolia, Asia. 'Roadrunner' dinosaur discovered 2010-03-30T09:36:00Z Spinosaurs, the sail-backed dinosaurs made famous by a star turn in the movie Jurassic Park III, belonged to a group of meat-eating dinosaurs called theropods. Sail-Backed Dinos Had Semiaquatic Lifestyle 2010-02-15T15:29:00Z The discovery, which the researchers reported last week in Nature, supports research showing that birds are dinosaurs, having descended from a group of bipedal dinosaurs called theropods. 2010-02-05T03:50:00Z About half of the 90 theropods appeared to be omnivores or herbivores, and shared certain physical characteristics, like beaks. Observatory: T. Rex?s Relatives Had More Items on Their Menu 2010-12-21T01:05:08Z Scientists believe that birds descended from theropods or bird footed dinosaurs in the Late Jurassic. 2010-01-28T19:29:00Z One type of dinosaur footprint found at the site was that of the Megalosaurus, a type of meat-eating theropod, whose name means "great lizard". 2010-01-20T12:52:00Z It may also provide clues as to why theropods thrived compared with other dinosaurs. Observatory: T. Rex?s Relatives Had More Items on Their Menu 2010-12-21T01:05:08Z The chicken-sized theropod was festooned with long feathers on its arms and legs. 2010-02-05T03:50:00Z The research may help scientists better understand how theropod dinosaurs eventually evolved into birds, and how they were able to take flight and begin living in trees. Observatory: T. Rex?s Relatives Had More Items on Their Menu 2010-12-21T01:05:08Z |
