A late Permian captorhinid from Rhodesia. American Museum novitates ; no. 2688

Abstract

"Two partial skulls from the late Permian Madumabisa Mudstone in the Middle Zambezi Basin of Rhodesia belong to the captorhinid genus Protocaptorhinus. Heretofore, Protocaptorhinus has been known only from the early Permian of Texas, whereas Africa has yielded only one other captorhinid, Moradisaurus, from Niger. The Captorhinidae is a monophyletic group (possibly including turtles) with these derived characters: downturned premaxilla, ectopterygoid and tabular absent, medial process of jugal. Protocaptorhinus differs from Romeria in having a shallow median parietal embayment and differs from remaining captorhinids in lacking a retroarticular process"--P. [1].
