Procolophonomorpha

Procolophonomorpha is an order or clade containing most parareptiles. Many papers have applied various definitions to the name, though most of these definitions have since been considered synonymous with modern parareptile clades such as Ankyramorpha and Procolophonia. The current definition of Procolophonomorpha, as defined by Modesto, Scott, & Reisz (2009), is that of as a stem-based group containing Procolophon and all taxa more closely related to it than to Milleretta. It constitutes a diverse assemblage that includes a number of lizard-like forms, as well as more diverse types such as the pareiasaurs. Lee 1995, 1996, 1997 argues that turtles evolved from pareiasaurs, but this view is no longer considered likely. Rieppel and deBraga 1996 and deBraga and Rieppel, 1997 argue that turtles evolved from sauropterygians, and there is both molecular and fossil (Pappochelys) evidence for the origin of turtles among diapsid reptiles.

gollark: Modems (requires a VLA like Anavrins' to be up to receive) and chat boxes.
gollark: Skynet is just a communications system. The relay handles interaction with a few ingame devices.
gollark: Yes, that would be your problem.
gollark: You'll have to do everything but the communication yourself, obviously.
gollark: I mean, in theory skynet - no relay needed - can be used to *send messages to and from* turtles.
