On Trophic Adaptations of Ornithosuchids (Archosauria)
摘要
Abstract
Ornithosuchidae differ from other carnivorous archosaurs in the unique morphology of the jaw apparatus and postcranial skeleton. Various, often opposite, points of view have been expressed regarding their trophic adaptations—from carnivory and scavenging to piscivory. The most reasonable hypothesis seems to be that ornithosuchids were medium sized hyperanisodont carnivorous macrophages. Moreover, there are some analogies between ornithosuchids and saber-toothed therapsids and mammals.
