The dentition of megalosaurid theropods

摘要: Theropod teeth are particularly abundant in the fossil record and frequently reported literature. Yet, dentition of many theropods has not been described comprehensively, omitting details on denticle shape, crown ornamentations enamel texture. This paucity information striking basal clades, thus making identification isolated difficult, taxonomic assignments uncertain. We here provide a detailed description Megalosauridae, comparison to distinction from superficially similar all major theropod clades. Megalosaurid dinosaurs characterized by mesial carina facing mesiolabially teeth, centrally positioned carinae both lateral crowns, terminating above cervix, short well-developed interdenticular sulci between distal denticles. A discriminant analysis performed dataset numerical data collected 62 taxa reveals that megalosau...
