Explore the fascinating world of theropod tooth morphology in this 46-minute Royal Tyrrell Museum Speaker Series talk. Delve into Derek Larson's research on non-avian theropod teeth from the Late Cretaceous in Alberta. Learn how tooth morphology can reveal patterns of evolution within a single formation and across multiple formations over time. Discover the use of discriminant function analysis and principal component analysis in studying theropod tooth disparity. Examine the relationships between various theropod groups, including dromaeosaurs, troodontids, and modern birds. Investigate new raptor species and their place in theropod evolution. Gain insights into morphological shifts across rock units and their implications for understanding theropod diversity. Conclude with an overview of future research directions in this field of paleontology.
