Here's What We Used to Think Dinosaurs Looked Like 2017-09-02T04:00:00Z The two halves of North America in the Cretaceous, Laramidia in the West, and Appalachia in the East, remained apart for millions of years, only knitting together completely around 60m years ago. A glimpse of when Canada's badlands were a lush dinosaur forest by the sea | Elsa Panciroli 2017-09-27T04:00:00Z This would've made Morturneria the Cretaceous equivalent of a gray whale, a reptile who was sifting the seas before the ancestors of cetaceans even began to enter the oceans. Paleo Profile: The Sieve-Toothed Plesiosaur 2017-09-10T04:00:00Z “We aren't running out of new types of feathered Jurassic and Cretaceous dinosaurs and can look forward to continued new discoveries,” he says. New Feathered Dinosaur Had Four Wings but Couldn't Fly 2017-08-28T04:00:00Z Patagotitan, which lived about 100 million years ago during the late Cretaceous Period, is considered a titanosaur, a diverse lineage of plant-eating, long-necked dinosaurs with long tails that walked on four legs. Which dinosaur is the biggest? There’s a new contender — and it’s alarmingly large. 2017-08-09T04:00:00Z Their extinction rates did not increase at the end of the Cretaceous; rather, origination of new species plummeted, and so diversity dropped. Evolution: Parallel lives : Nature : Nature Research 2017-08-08T04:00:00Z I asked him what kind of life lived in Cretaceous Alberta. A glimpse of when Canada's badlands were a lush dinosaur forest by the sea | Elsa Panciroli 2017-09-27T04:00:00Z That's the conclusion of the first scientific description of an especially large titanosaur, which lumbered across what is now Argentina during the Cretaceous.

Underground magma triggered Earth’s worst mass extinction with greenhouse gases | Howard Lee 2017-08-01T04:00:00Z 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 When thinking of Cretaceous animal faunas, we tend to imagine the dinosaurs, pterosaurs, plesiosaurs and other big beasts. J.Lo and Other Araripemydid Pleurodires 2017-08-05T04:00:00Z Just as importantly, they lived in environments quite different from those of the Cretaceous. Evolution: Parallel lives : Nature : Nature Research 2017-08-08T04:00:00Z Unable to break into a sprint, it must have stepped its way through the Cretaceous Period. Tyrannosaurus rex couldn’t run, but it was a speedy walker 2017-07-19T04:00:00Z As Sellers says in the study, T. rex was not one of the more “athletic” dinosaurs on the Cretaceous landscape—and that’s not a huge surprise to most paleontologists.

Baby Bird from Time of Dinosaurs Found Fossilized in Amber 2017-06-07T04:00:00Z This is why bird paleontologists are looking with great interests at the period beyond the Cretaceous – Paleogene extinction, because this is where the ancestors of all our modern birds are to be found. Happy feet: why a 61m-year-old penguin foot has researchers dancing for joy 2017-04-05T04:00:00Z The tooth was obviously from some sort of herbivorous Cretaceous dinosaur, but what kind? When Horned Dinosaurs Traveled East 2017-06-25T04:00:00Z Whether the immense carnivores courted like oversized albatrosses, offered gifts of semi-rotted triceratops meat, or simply got down to business without pretence is a vignette lost to Cretaceous time. Bloodthirsty chomp-monster or sensitive lover? Time to rethink Tyrannosaurus rex | Brian Switek 2017-04-03T04:00:00Z The bipedal carnivores spanned the globe for 14 million years in the late Cretaceous era, and fossils from Mongolia to North America offer scientists today a wealth of data on their biomechanics, anatomy, and evolution. Tyrannosaur’s sensitive skin may have helped it capture prey 2017-03-30T04:00:00Z The work is also revealing the last chapters of the ichthyosaur story, which culminated with the animals’ extinction during the Upper Cretaceous, some 30 million years before dinosaurs disappeared. How giant marine reptiles terrorized the ancient seas 2017-03-28T04:00:00Z The finding of this new fossil penguin foot alongside more primitive species of penguins indicates that penguin diversity early after the Cretaceous - Palaeogene extinction event was larger than expected.

This cat-sized pterosaur looks like adorable origami 2016-08-30T04:00:00Z The pigmentation patterns on those Cretaceous marine reptiles followed a pattern called countershading, in which the animal’s back is dark and the belly is lighter. Dinosaur ‘wore’ forest camouflage to hide from predators 2016-09-14T04:00:00Z They suggest the existence of a species about 77 million years ago, during the late Cretaceous period, that was much smaller than the giant pterosaurs thought to dominate then.
