Abstract. An important parameter in studying the macroevolutionary history of a clade is the variation of its body size. However, the analysis of this parameter in archosauromorphs has been restricted to Archosauria, and the disparity in body size has not been exhaustively explored. In the present work, we study the variation in body size of more t...

The oldest archosauromorphs (dinosaurs, birds, crocodiles, and their stem-taxa) are recorded in middle−upper Permian rocks, but it was not after the Permo−Triassic mass extinction that the group shows a substantially high taxonomic richness and ecomorphological disparity. The early evolutionary history of the Archosauromorpha during the Early and M...
