Latest Albertosaurus Stories
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.
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.
Tyrannosaurs are more than large carnivores at the top of the food chain.
Carnivorous but smaller T. rex relative shared environment with larger cousins.
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
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.
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.
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, 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...
