We’ve Rarely Seen a Dinosaur Brain Like This Before 2020-11-03T05:00:00Z We often find more than one sauropod species from a given time and place. How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z "Imagine the huge sauropods from 'Jurassic Park' and consider that the tiny skulls of their babies, still inside their eggs, are just a couple of centimeters long." Largest dinosaur ever had 'rhino-like horn' at birth, research reveals 2020-09-10T04:00:00Z Part of a backbone described by fossil hunter E. D. Cope in the 19th century seemed to suggest a sauropod, known as Amphicoelias, that measured almost twice as long as any other. Why the World’s Biggest Dinosaurs Keep Getting Cut Down to Size 2020-10-13T04:00:00Z This is different from older sauropods, where the eyes face to the sides. Fossil Reveals ‘One of the Cutest Dinosaurs’ Ever Found 2020-08-27T04:00:00Z A few dinosaur groups, including sauropods, laid hard-shelled eggs.

Why the World’s Biggest Dinosaurs Keep Getting Cut Down to Size 2020-10-13T04:00:00Z But why younger sauropods and not older sauropods needed to be good at gauging the distances between things isn’t at all clear. Fossil Reveals ‘One of the Cutest Dinosaurs’ Ever Found 2020-08-27T04:00:00Z Gigantic sauropods, some of the largest creatures to ever roam the Earth, apparently once walked only on their front feet. Giant 'thunder lizard' dinosaurs may have walked on their front feet only, findings reveal 2020-01-28T05:00:00Z Because the amount of weight supported by a column increases with thickness, we can estimate the mass of a sauropod based on the cross-sectional area of its limb bones. How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z Dystrophaeus is the oldest known sauropod from North America, for example, and lived millions of years before the likes of Diplodocus. The Time of Giants 2020-01-04T05:00:00Z Some of the largest skeletons in places such as the Smithsonian’s National Museum of Natural History — those of mammoths, mastodons, sauropod dinosaurs and the Tyrannosaurus rex — belong to long-extinct species. We learned a lot about whales this year 2019-12-28T05:00:00Z But although it doomed Tyrannosaurus rex and Triceratops, the sauropods and the hadrosaurs, the asteroid actually set one lineage of dinosaurs on a path to glory: that of modern birds. Solving the Mystery of Songbird Diversity 2019-11-07T05:00:00Z Researchers studied three sauropod trackways in Texas that were unusual because they seemed to be manus-only, meaning footprints created only by their front limbs. Giant 'thunder lizard' dinosaurs may have walked on their front feet only, findings reveal 2020-01-28T05:00:00Z About 200 of the 250 sauropod species on record are known from fossils that include limb bones complete enough to measure this way.

The Time of Giants 2020-01-04T05:00:00Z Their previous work helped show that sauropods were eating machines that gulped down vegetation without chewing. Sauropods grew big by munching ‘superfoods’ with sturdy beaks 2019-10-17T04:00:00Z Then, at some point later, a wandering sauropod stepped on the sediment above the shell and crushed part of the fossil-in-the-making. Did a Jurassic Dinosaur Smoosh a Turtle? 2019-09-15T04:00:00Z As Science Alert reported, some experts believe that sauropods' forefeet are the only ones that leave track marks on certain ground surfaces because their rear limbs support less weight, therefore make less of an impression. Giant 'thunder lizard' dinosaurs may have walked on their front feet only, findings reveal 2020-01-28T05:00:00Z I recently obtained these measurements and used them to chart sauropod body mass evolution. How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z Looking at the corrected stacks of dinosaurs, based on what’s known now, there are certain Morrison Formation times that boasted more sauropod diversity than others. The Time of Giants 2020-01-04T05:00:00Z They fermented modern horsetails for 3 days to simulate the journey through a sauropod's gut and measured the volume of gas produced—an indicator of energy content. Sauropods grew big by munching ‘superfoods’ with sturdy beaks 2019-10-17T04:00:00Z Some parts of the shell also seem to be rotated in a way consistent with a sauropod step. Did a Jurassic Dinosaur Smoosh a Turtle? 2019-09-15T04:00:00Z "Without a doubt made by a sauropod, but as I interpret them, made by an individual while swimming," Bird wrote in a letter in 1940. Giant 'thunder lizard' dinosaurs may have walked on their front feet only, findings reveal 2020-01-28T05:00:00Z It turns out that over their long history, sauropods evolved a wide range of sizes. How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z The massive sauropod dinosaurs crossing the same flat might have been looking for a less cluttered way to a new area than passing through a thick inland forest.

Sauropods grew big by munching ‘superfoods’ with sturdy beaks 2019-10-17T04:00:00Z Large sauropod tracks were found nearby, and seem a good fit for a downward force that could have pulverized part of the shell. Did a Jurassic Dinosaur Smoosh a Turtle? 2019-09-15T04:00:00Z The specimens included skeletal parts from giant herbivorous sauropods and meat-eating theropods. 'Mission Jurassic' dinosaur dig closes for winter 2019-09-02T04:00:00Z I plotted these species on an evolutionary tree and stretched the tree over time to see when and how many times sauropods increased or decreased their body mass. How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z It's unclear exactly what sauropod the bone belongs to just yet, but the group includes brachiosaurus and brontosaurus, seen famously in "Jurassic Park." Massive 1,100-pound bone of ‘world’s biggest dinosaur’ found 2019-07-26T04:00:00Z The researchers found that sauropod teeth typically show surface wear only about halfway down to the jaw. Sauropods grew big by munching ‘superfoods’ with sturdy beaks 2019-10-17T04:00:00Z Even if the actual scenario for this specific fossil isn’t upheld by future study, we can still envision a hefty sauropod ambling over wet sediment, feeling some unexpected crunch beneath a foot before ambling on. Did a Jurassic Dinosaur Smoosh a Turtle? 2019-09-15T04:00:00Z There are no long-necked sauropod dinosaurs, no huge allosaurs, and no close relatives of Iguanodon that were very common earlier in the Cretaceous. Tiny Tyrannosaur Named the "Coyote King" 2019-05-18T04:00:00Z Most sauropods were not exceptional in size compared with the largest terrestrial mammals.

How Sauropod Dinosaurs Became the Biggest Land Animals Again and Again 2023-08-15T04:00:00Z Purely because I’ve never actually said much about it before, I want to talk here about mokele-mbembe, the alleged ‘living sauropod’ of the Congo. Misreading the Mokele-Mbembe (the Mokele-Mbembe, Part 1) 2018-06-10T04:00:00Z The long-necked sauropods, for example, are thought to have opted for a lay ‘em and leave ‘em strategy with their eggs, like modern sea turtles, where survival of their young was merely a numbers game. A Tiny Reason for Big Dinosaurs to Gather Together 2018-05-27T04:00:00Z Even though the teeth of Allosaurus, Ceratosaurus, and Torvosaurusall differ from each other in details like cross section and serrations, the offending theropod in this case didn’t leave any teeth in the sauropod bone itself.

Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z There was some speculation involved in that skull reconstruction, but it was really constrained by the surrounding anatomy and other more completely known sauropod skulls, so in the end it is a very accurate model. Paleo Dream Jobs: Bringing Dinos Back to Life 2012-04-02T21:46:20.767Z The long necks of sauropods did not evolve primarily through sexual selection. Did dinosaurs and pterosaurs practise mutual sexual selection? 2012-01-05T15:45:07.957Z The researchers are investigating whether other very large animals, such as sauropod dinosaurs, had similar innovations. Elephants Have a Sixth 'Toe' 2011-12-21T19:02:00Z Because sauropods were perceived as without a place, unsuited for land or sea, they came to be seen as unwieldy, overgrown, archaic herbivores fated for rapid extinction or, at least, marginalization by more “advanced” dinosaurs. Triumph of the Titans: How Sauropods Flourished (preview) 2012-04-30T12:15:00.190Z The extensive wear on sauropod tooth – indicative of raking or slicing – shows extensive use of the teeth as feeding tools. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z But Fricke is "pretty confident" that he will be able to tell whether other dinosaurs stayed at home or joined the sauropods on their migration. Tooth Chemistry Reveals Sauropod Sojourns 2011-10-27T17:15:01.957Z An analysis of fossilized teeth adds further evidence that the long-necked dinosaurs called sauropods — the largest land creatures — went on road trips to fill their gargantuan appetites. Dino dining: Study suggests giant dinosaurs in American West ventured far for food, water 2011-10-26T17:30:11Z The new research the study eventually spurs, Bonnan says, will test the idea that ever-hungry sauropods traveled hundreds of kilometers for the leafy snacks they preferred. Sauropod Salad Bar 2011-10-26T18:28:31Z In 1858, Maryland’s state geologist, Philip Thomas Tyson, recovered two sauropod teeth near here. Dinosaur hunters make curious find in Prince George?s County 2011-09-22T00:50:13Z Again, this seems incompatible with the presence of a trunk, as if sauropods had proboscides, wouldn’t they be grabbing foliage with the trunk tip, and then passing it into the mouth, over the teeth? Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z The evidence collected by Fricke and his colleagues takes the form of fossil enamel chipped from 32 teeth that belonged to sauropods of the genus Camarasaurus. Tooth Chemistry Reveals Sauropod Sojourns 2011-10-27T17:15:01.957Z The researchers analyzed 32 sauropod teeth collected in Wyoming and Utah. Dino dining: Study suggests giant dinosaurs in American West ventured far for food, water 2011-10-26T17:30:11Z Robert Eagle, an evolutionary biologist at the California Institute of Technology, and colleagues analyzed 11 dinosaur teeth from sauropods. Observatory: Raising the Temperature on Cold-Blooded Dinosaurs 2011-06-24T21:33:38Z Still, because of their sheer enormous size, sauropod dinosaurs would be expected to retain their body heat more efficiently than smaller warm-blooded animals, like humans, even if dinosaurs themselves were cold-blooded, Eagle said. Researchers take dinosaurs' temperature with teeth 2011-06-24T12:10:11Z I argue that the broad muzzles and super-long necks of sauropods are incompatible with trunk presence. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z 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 The largest sauropods weighed 100 tons and were 120 feet long. Dino dining: Study suggests giant dinosaurs in American West ventured far for food, water 2011-10-26T17:30:11Z While several sauropod species are mentioned here and there, the focus is on their biology, not identification. Giant Dino exhibit at the American Museum of Nature Science, or, why I should not be a photojournalist 2011-04-16T04:15:00.240Z Eagle said his team started with sauropods because their plant-munching teeth were bigger and contained more enamel to work with. Researchers take dinosaurs' temperature with teeth 2011-06-24T12:10:11Z The lack of appropriate facial musculature, the absence of muscle attachment sites, and the presence of small facial nerves all show that sauropods did not, and could not have had, trunks. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z By what physiological strategy of heart, lungs and metabolism were the largest of sauropod species able to thrive over a span of 140 million years? Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z "The study is a valuable contribution for understanding the evolution of the long necks of sauropods," says biologist Andreas Christian of the University of Flensburg in Germany. How a Dinosaur Is Like a Vacuum Cleaner 2011-03-23T01:01:00Z And when he retired 20 years ago, he devoted himself to the study of sauropods, the order of large, plant-eating dinosaurs that Dr. Taylor also favors. Dinosaur-Hunting Hobbyist Makes Fresh Tracks for Paleontology 2011-02-28T21:22:34Z Scientists are still debating whether sauropods lifted their necks to feed from the tops of trees, as giraffes do. Dinosaur Munchies May Have Bulked Up Pine Cones 2011-02-23T16:58:53Z For previous Tet Zoo articles on sauropod biology, diversity and behaviour, see… Anon. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z The sauropod’s neck became what the hook-and-ladder is to a firefighter: a means of extended reach that could be critical. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z "Let's just leave it there and not ask the sauropods to raise their necks." How a Dinosaur Is Like a Vacuum Cleaner 2011-03-23T01:01:00Z In 1979, he helped prove that paleontologists had mounted the wrong head on a sauropod named Apatosaurus. Dinosaur-Hunting Hobbyist Makes Fresh Tracks for Paleontology 2011-02-28T21:22:34Z Still, one shouldn't rush to blame sauropods, he says. Dinosaur Munchies May Have Bulked Up Pine Cones 2011-02-23T16:58:53Z Necks for sex: sexual selection as an explanation for sauropod dinosaur neck elongation. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z In any event, sauropods could outcompete other plant eaters and over time, as one scientist wrote, “enter the niche of giants.” Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z What's interesting is that if it were a sauropod that could move particularly fast, you would expect to see very strong muscles on the back of the leg to pull it along. Move over T.rex - make way for 'thunder-thighs' 2011-02-23T02:32:12Z One idea: Mama sauropods buried their eggs immediately before the asteroid impact; months later, the youngsters hatched into a devastated world to found a new herd. Geologist claims a few dinosaurs survived extinction event 2011-01-29T23:06:02Z Until recently, the remains of intermediates closely related to the sauropods were extremely rare and fragmentary. How Giants Conquered the Earth 2011-01-26T22:20:33Z Unlike most tetrapods, the bony nostrils of most sauropods are dorsally located: in diplodocoids they’re located right up over the eyes in a region you might term the forehead. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z The heart of a mouse beats 700 times a minute; a human, 72; an elephant, 28; a sauropod, less than 10. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The team also believes the find is significant for its position in Earth history, in that it challenges the notion that sauropods began to disappear in the Early Cretaceous. Move over T.rex - make way for 'thunder-thighs' 2011-02-23T02:32:12Z After the sauropod died in what is now northern New Mexico, the calcium in its bones was eventually replaced by harder, longer-lasting minerals, including uranium. Geologist claims a few dinosaurs survived extinction event 2011-01-29T23:06:02Z Eodromaeus also resembles a dinosaur called Eoraptor in size and structure, but Eoraptor was most likely an early ancestor of sauropods, which included primarily long-necked herbivores. Observatory: Pet-Size Dinosaur Was Early Ancestor to T. Rex, Researchers Say 2011-01-13T22:53:01Z Like Coombs, Munns wondered if the dorsally located bony nostrils of sauropods might indicate the presence of a proboscis, and he went as far as providing the animal with a fairly long, elephant-like, tubular proboscis. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z If correct, he said in the interview, this and other evidence suggests that sauropods were warm-blooded to some extent. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z In the past 20 years, however, we are finding more sauropods from the Early Cretaceous period, and the picture is changing. Move over T.rex - make way for 'thunder-thighs' 2011-02-23T02:32:12Z Because Herrerasaurus was found near some early sauropods and ornithischians, the new finding strongly suggests that all three main lineages diverged early on. Observatory: Bones Show Early Divergence of Dinosaur Lineage 2009-12-15T19:58:00Z The dinosaur relatives were far less imposing than tyrannosaurs, triceratops and sauropods. Footprint Fossils Offer Earliest Evidence of Dinosaurs? Ancestors 2010-10-06T19:44:00Z One argument that gets consistently trotted out whenever the possibility of sauropod trunks is mentioned concerns the absence of facial muscles in sauropods, and in dinosaurs and reptiles in general. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z The fact that dinosaurs’ distant relative the crocodile has a respiratory system somewhat like a bird’s suggested to scientists that it might also have been true of sauropods. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The most famous is Brontosaurus, the genus name of the sauropod dinosaur. Taxonomy: Fly in the ointment 2010-04-29T11:22:00Z The bones found at Dinosaur National Monument belonged to a type of sauropod — long-necked plant-eaters that were said to be the largest animal ever to roam land. New Species of Dinosaur Found in Eastern Utah Rock 2010-02-24T19:39:00Z But these ancient plants were a favourite of huge sauropod dinosaurs that used to eat them in bulk. Meet a European woodmouse that eats like a dinosaur 2010-02-19T12:45:00Z A similar line of logic could be used for cranial musculature: might sauropods have somehow evolved totally novel musculature that ‘allowed’ the evolution of a trunk? Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z In time, however, sauropods seemed to feast on their enormous size. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z If snapshots tell anything at all, these told that Oswald was the father of a mammoth sauropod and had merely dug up the baby in a fossil bed somewhere. Ma Pettengill The discovery included two complete skulls from other types of sauropods — an extremely rare find, scientists said. New Species of Dinosaur Found in Eastern Utah Rock 2010-02-24T19:39:00Z Structure and evolution of a sauropod tooth battery. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z They are entirely absent in the skulls of sauropods. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z But this does not necessarily mean, he said, that sauropods were fully warm-blooded. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The Rutland Cetiosaurus: the anatomy and relationships of a Middle Jurassic British sauropod dinosaur. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z Of the 120 or so known species of sauropods, complete skulls have been found for just eight. New Species of Dinosaur Found in Eastern Utah Rock 2010-02-24T19:39:00Z Still, he said, the sauropod “is an incredible animal, one of the best land animals that’s been invented.” Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Well, ok, but remember that we can only infer structures – particularly super-controversial and counter-intuitive structures like sauropod trunks – when we have strong positive evidence. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z In the team’s book, Dr. Clauss conceded that there was debate on the metabolic rates and a lack of consensus on the nature of the sauropod cardiovascular system. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Nothing in the dinosaur world was quite like the sauropods. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The skulls — including one that's complete and intact and another that's complete but in pieces — offer new clues about how sauropods ate their food. New Species of Dinosaur Found in Eastern Utah Rock 2010-02-24T19:39:00Z “We actually have been re-engineering a sauropod,” said P. Martin Sander, a paleontologist at the University of Bonn and leader of the research team. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z As mentioned above, the sauropod trunk hypothesis mostly came about because most sauropods have dorsally located bony nostrils. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z He noted that among many scientists a direct link between the sauropod respiratory system and gigantism “is not yet compelling.” Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z This was seemingly the only efficient way for sauropods to satisfy their appetites and to diversify into some 120 genera, beginning more than 200 million years ago. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z An early and not especially large sauropod, it lived 160 million years ago, laid eggs and possibly lived in a herd. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The model focuses attention on the animal’s 30-foot neck and small skull and jaws to illustrate the remarkable biology and behavior of sauropods. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z This is why newer illustrations of sauropods show them with nostrils that are more anteriorly located than those in older illustrations. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z The research, Dr. Dodson added, raises the related question of why mammals have never approached in size the larger sauropods. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Early in their investigations, material scientists in the German-Swiss group proposed that sauropod bone had superior mechanical properties compared with large mammal bone, which would have given these dinosaurs stronger skeletons to support heftier bodies. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The hypothesis was tossed aside after tests showed that sauropod and cow bone tissue had the same strength. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Then the investigators found no evidence that availability of food and the physical and chemical conditions in the Mesozoic era were sufficiently different to have accounted for sauropod gigantism. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z The osteological evidence for fleshy nostril position in sauropods is flatly incompatible with the trunk hypothesis. Junk in the trunk: why sauropod dinosaurs did not possess trunks (redux, 2012) 2012-11-20T14:15:00.200Z “They were to mammals what sauropods were to dinosaurs,” he said. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z “What makes a sauropod a sauropod is its most conspicuous feature, its enormously long neck,” he said. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Dr. Sander and his colleagues think that two of the sauropod’s primitive inheritances probably account for this. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z A small head, of course, took a load off the sauropod neck, presumably allowing it to grow longer. Giants Who Scarfed Down Fast-Food Feasts 2011-04-11T19:38:35Z Not cranes or masts, but beams: the biomechanics of sauropod necks.
