A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorph) and other “prororosaurs” and its implications for the early evolution of stem archosaurs
The historical clade “Protorosauria” represents an important group of archosauromorph reptiles that had a wide geographic distribution between the Late Permian and Late Triassic. “Protorosaurs” are characterized by their long necks, which are epitomized in the genus Tanystropheus and in Dinocephalosaurus orientalis. Recent phylogenetic analyses have indicated that “Protorosauria” is a polyphyletic clade,...Spiekman, Stefan N F ; Fraser, Nicholas C ; Scheyer, Torsten M
