Thecodont now considered an obsolete term, was formerly used to describe a diverse range of early archosaurs that first appeared in the Latest Permian and flourished until the end of the Triassic period. The group includes the ancestors of dinosaurs , and ancestors of pterosaurs, and crocodilians, as well as a number of extinct forms that did not give rise to any descendants. Thecodonts are defined by certain shared primitive features, such as the suborbital fenestra and teeth in sockets. The name thecodont" is Greek for "socket-tooth," referring to the fact that thecodont teeth were set in sockets in the jawbones an archosaurian characteristic that was inherited by the dinosaurs."
