Tyrannosaurus packs
2014-07-26 04:30:36

redOrbit Staff & Wire Reports - Your Universe Online Three sets of tyrannosaur tracks discovered in northeastern British Columbia reveal the bipedal carnivores likely traveled in packs, according to new research published in Wednesday’s edition of the journal PLOS ONE. According to Emily Chung of CBC News, this marks the first time that more than a single tyrannosaur print has ever been found in one place. That alone made the find interesting enough, since it allows...

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...

Carnivorous but smaller T. rex relative shared environment with larger cousins Now, just a few weeks after tiny, early Raptorex kriegsteini was unveiled, a new wrench has been thrown into the family tree of the tyrannosaurs. The new Alioramus altai"”a horned, long-snouted, gracile cousin of Tyrannosaurus rex"”shared the same environment with larger, predatory relatives. A paper published this week in the Proceedings of the National Academy of Sciences describes this exceptionally...

Remains of Cretaceous 'anteater' found during Albertosaurus dig reveal new species of tiny dino An unusual breed of dinosaur that was the size of a chicken, ran on two legs and scoured the ancient forest floor for termites is the smallest dinosaur species found in North America, according to a University of Calgary researcher who analyzed bones found during the excavation of an ancient bone bed near Red Deer, Alberta. "These are bizarre animals. They have long and slender legs, stumpy arms...

New study on hadrosaur bones shows fast growth, reproduction rates With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that it had at least one advantage: It grew to adulthood much faster than its predators, giving it superiority in size. In a study published online today in the Proceedings of the Royal Society of London B: Biological Sciences, scientists...

WASHINGTON -- Even the powerful tyrannosaurs seem to have encountered a midlife crisis. Once they made it to about age 2 they could take on just about any other predator and had very little mortality until they reached sexual maturity in their teens, researchers report in Friday's issue of the journal Science. "Survivorship stabilized at between two and four percent per year until midlife at which point they went through an honest-to-God midlife crisis," Gregory M. Erickson, who teaches...

Barnum Brown (February 12, 1873 – February 5, 1963) was an American Paleontologist best known for his contributions to the American Museum of Natural History, and his discovery of the first documented Tyrannosaurus rex remains. Brown was known less as a published paleontologist and more often as an energetic excavator, perhaps the greatest fossil collector of all time. Barnum Brown was born in Carbondale, Kansas, and was named after P.T. Barnum – of traveling circus fame, but no...

Daspletosaurus
2013-04-28 18:27:18

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...

Gorgosaurus, meaning "fierce lizard", is a genus of tyrannosaurid theropod dinosaur from the Late Cretaceous Period (77 to 74 million years ago) that lived in what is now western North America. It has been discovered in Alberta, Canada and possibly Montana, USA. Only one type species is known, G. libratus. Gorgosaurus was first described by Lawrence Lambe in 1914. Several specimens have been discovered, the first by Charles M. Sternberg in 1913. It was also the first tyrannosaurid dinosaur to...

Dryptosaurus, meaning "tearing lizard", is a genus of primitive tyrannosaur dinosaur from the Late Cretaceous Period (Maastrichtian Age) and lived in what is now eastern North America. It was discovered in New Jersey by workers in a quarry. It was described by E.D. Cope and subsequently named it Laelaps (meaning "storm wind", named after a dog in Greek mythology that never failed to catch what it was hunting). It became one of the first dinosaurs to be described from North America. It was...

This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
