Velociraptors Didn't Turn Down Free Meals
2012-03-07 07:43:28

Scientists have found evidence that specialized predators, such as the velociraptor, may not have been willing to turn down a free meal. A bone from a pterosaur (or “Pterodactyl”) has reportedly been found in the gut of a velociraptor that lived in the Gobi desert of Magnolia more than 75 million years ago. The scientists published their findings online in Palaeogeography, Palaeoclimatology, and Palaeoecology. This discovery suggests that the velociraptor may not have only...

First record of a sauropod dinosaur in Antarctica suggests more widespread distribution of this species than previously thought For the first time, the presence of large bodied herbivorous dinosaurs in Antarctica has been recorded. Until now, remains of sauropoda - one of the most diverse and geographically widespread species of herbivorous dinosaurs - had been recovered from all continental landmasses, except Antarctica. Dr. Ignacio Alejandro Cerda, from CONICET in Argentina, and his...

New Evidence Says Three Dinosaurs Are Actually One
2011-12-15 13:41:51

Researchers report that they have found further evidence that genera of the Triceratops actually represent different individuals that all belong to the Triceratops genus. The three genera, Triceratops, Torosaurus, and Nedoceratops, were thought at one time or another thought to be distinct. However, the work by John Scanella of Montana State University and colleagues shows that these dinosaurs are actually the result of maturity.  They focused on a single skull that has been the...

Image 1 - Nest Of Dinosaurs Discovered In Mongolia
2011-11-21 14:43:24

Archaeologists have discovered a nest containing 15 fossilized juvenile Protoceratops andrewsi dinosaurs in Mongolia. The discovery is the first nest of this genus ever found and the first indication that Protoceratops juveniles remained in the nest for an extended period. David Fastovsky, URI professor of geosciences with the University of Rhode Island, said the nest was 2.3 feet in diameter and his team discovered it in the Djadochta Formation at Tugrikinshire, Mongolia. "Finding...

Researchers have discovered that an evolutionary change from 65 million years ago may have set the pace for the rapid growth rate of present-day flowering plants. Taylor Feild, associate professor of ecology and evolutionary biology at the University of Tennessee, Knoxville, in collaboration with a group of other researchers from around the world, have determined the precise dates that angiosperms, or flowering plants, experienced two surges in growth during the Cretaceous period. Their...

Persistence paid off for a University of Alberta paleontology researcher, who after months of pondering the origins of a fossilized jaw bone, finally identified it as a new species of pterosaur, a flying reptile that lived 70 million years ago. Victoria Arbour says she was stumped when the small piece of jaw bone was first pulled out of of a fossil storage cabinet in the U of A's paleontology department. "It could have been from a dinosaur, a fish or a marine reptile," said Arbour. " Arbour,...

Tyrannosaurs are more than large carnivores at the top of the food chain We've all heard this story: the Late Cretaceous of Asia and North America"”about 65 million years ago"”was dominated by several large-headed, bipedal predatory dinosaurs like Tyrannosaurus rex and Tarbosaurus that had tiny arms. But a decade of new fossil discoveries that have more than doubled the number of known tyrannosaur species has changed this tale. Older and smaller tyrannosaurs have made the...

Othniel Charles Marsh
2013-10-14 09:50:48

Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American paleontologist, specializing primarily in vertebrates. He is highly renowned as one of the most prominent scientists of his time, having discovered and described dozens of new species. Marsh is also credited with developing what is currently the most widely accepted theory of the origin of birds. Marsh was born in Lockport, New York, to a family of moderate means. Thanks to the generosity of his uncle, George...

Styracosaurus
2013-04-29 14:54:48

Styracosaurus, meaning “spiked lizard” from the Ancient Greek styrax “spike at the butt-end of a spear-shaft” and sauros “lizard” was a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period, about 76.5 to 75 million years ago. It had four to six long horns, stretching from its neck frill, a smaller horn on each cheek, and a single horn jutting out from its nose, which may have been up to 2 feet long and 6 inches wide. The function/functions of these horns and frills...

Thescelosaurus

Thescelosaurus, meaning “godlike”, “wondrous”, or “marvelous” and “lizard” was a genus of small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. It was a member of the last dinosaurian fauna before the Cretaceous-Paleogene extinction event around 65.5 million years ago. The completeness and preservation of many of its specimens illustrate that it might have preferred to live near streams. This bipedal ornithopod is known from...

Daspletosaurus

Daspletosaurus, meaning “frightful lizard” is a genus of tyrannosaurid theropod dinosaur that resided in western North America between 77 and 74 million years ago, during the Late Cretaceous Period. Fossils of the only named species were found in Alberta, although other possible species from Alberta and Montana wait for description. Daspletosaurus is closely related to the much larger and more current Tyrannosaurus. Like most of the known tyrannosaurids, it was a multi-ton bipedal...

Megalaosaurus, meaning “Great Lizard”, from Greek megalo, meaning ‘big’ or ‘tall’ and sauros, meaning “lizard”, is a genus of large and meat-eating theropod dinosaurs of the Middle Jurassic period of Europe. It’s significant as the first genus of dinosaur, outside of birds, to be described and named. Megalosaurus might have been the first dinosaur to be described in scientific literature. Part of a bone was recovered from a limestone quarry at Cornwell by Chipping Norton,...
