Diversity and variation of theropod dinosaur teeth from the uppermost Santonian Milk River Formation (Upper Cretaceous), Alberta: a quantitative method supporting identification of the oldest dinosaur tooth assemblage in Canada
TL;DR: The Santonian Deadhorse Coulee Member of the Milk River Formation preserves the oldest dinosaur body fossils found in Alberta as mentioned in this paper, however, vertebrate remains consist almost exclusively of isolated ele...
Journal ArticleDOI
Dental Disparity and Ecological Stability in Bird-like Dinosaurs prior to the End-Cretaceous Mass Extinction.
TL;DR: The data provide strong support that extinction within this group occurred suddenly after a prolonged period of ecological stability and propose that diet may have been an extinction filter and suggest that granivory associated with an edentulous beak was a key ecological trait in the survival of some lineages.
Journal ArticleDOI
Quantifying tooth variation within a single population of Albertosaurus sarcophagus (Theropoda: Tyrannosauridae) and implications for identifying isolated teeth of tyrannosauridsThis article is one of a series of papers published in this Special Issue on the theme Albertosaurus.
TL;DR: In this paper, the authors documented the variation within 140 disassociated and seven in situ tyrannosaur teeth from the Upper Cretaceous (lower Maastrichtian) monodominant Albertosaurus sarcophagus (Theropoda: Tyrannosauridae) bonebed.
Journal ArticleDOI
Tooth counts through growth in diapsid reptiles: implications for interpreting individual and size-related variation in the fossil record
Caleb M. Brown,Collin S. VanBuren,Derek W. Larson,Kirstin S. Brink,Nicolás E. Campione,Matthew J. Vavrek,David C. Evans,David C. Evans +7 more
TL;DR: The hypothesis that variation in tooth count is driven primarily by growth is rejected and growth trajectories of smaller reptilian taxa show increases in tooth counts and, although current samples are small, suggest potential correlates between tooth count trajectories and adult size.
Journal ArticleDOI
A new species of troodontid theropod (Dinosauria, Maniraptora) from the Horseshoe Canyon Formation (Maastrichtian) of Alberta, Canada
TL;DR: A new taxon is erected, Albertavenator curriei gen. et sp.
