The most common ichnogenus in the Peace River Canyon is Amblydactylus, a large bipedal herbivore. The morphology of the hand and footprints suggest that the tracks and trackways were made by hadrosaurs, and the ichnites might represent the earliest record of these dinosaurs. Amblydactylus tracks...

Cranial material of Sinraptor dongi (Upper Jurassic, Xinjiang, China), Gorgosaurus libratus, Daspletosaurus torosus (Upper Cretaceous, Alberta, Canada), and other large theropod dinosaurs exhibit similar paleopathological anomalies indicative of aggressive intra- or interspecific biting. Tooth...

A new microvertebrate site (≈72 Ma) in the Horseshoe Canyon Formation, south-central Alberta, is a deflational lag in interbedded silty shales. The site represents deposition on a waterlogged coastal plain ≈100 km to the west of the Bearpaw Sea. Approximately two-thirds (n=224) of the 388...

We describe a small dromaeosaurid dinosaur. Bambiraptor feinbergi n. gen. and n. sp., based upon a nearly complete fossil skeleton from the Two Medicine Formation (Upper Cretaceous) of Montana. Widely known as Bambi, this skeleton is a well-preserved subadult that is about 75 percent adult size....

The Gobi Desert is famous for providing one of the worlds best preserved Cretaceous terrestrial faunas, including dinosaurs and mammals. Beginning with the Central Asiatic Expeditions in the 1920s, through the Polish-Mongolian Expeditions in the 1960s-1970s, Soviet-Mongolian Expeditions in 1970s,...

Tyrannosauridae can be subdivided into two distinct subfamilies-the Albertosaurinae and the Tyrannosaurinae. Previously recognized subdivisions Aublysodontinae and Shanshanosaurinae are rejected because they are based on insufficient material and juvenile specimens. Our results are based upon a...

Beautifully preserved, nearly complete theropod skeletons from Alberta (Canada) allow re-evaluation of the taxonomic status of North American tyrannosaurids. It is concluded that the most parsimonious interpretation of relationships leads to the separation of the two species of Albertosaurus...

Samman, T., Hills, L. V., Powell, G. L., Currie, P. J.
Gross tooth morphology and serration morphology were examined to determine a quantifiable method for classifying tyrannosaurid tooth crowns from western North America From the examination of teeth in jaws, tyrannosaurid teeth could be qualitatively assigned to one of five types based on the...

Variation in premaxillary tooth count and a developmental abnormality in a tyrannosaurid dinosaur

Tanke, D. H., Currie, P. J., Miyashita, T.
Premaxillary tooth count tends to be stable amongst toothed dinosaurs, and most theropods have four teeth in each premaxilla. Only one case of bilaterally asymmetric variation is known in theropod premaxillary dentition, and there is no record of ontogenetic or individual variation in...
