Two New Pelycosaurs from the Lower Permian of Oklahoma Produced by Chris Curnow, Woodie4, Joseph Cooper and the Online Distributed Proofreading Team at https://www.pgdp.net "Two New Pelycosaurs from the Lower Permian of Oklahoma" by Richard C. Fox is a scientific publication written in the early 1960s. The work focuses on paleontological findings related to two newly identified genera of pelycosaurs discovered in early Permian fissure deposits in Oklahoma. This book presents a detailed examination and classification of these prehistoric reptiles, contributing to the understanding of their evolution and relationships to other families within the broader context of reptilian history. In the main body of the text, Fox describes two new genera: Delorhynchus priscus and Thrausmosaurus serratidens. He provides specific details about the morphology and fossilized remains of these organisms, including their teeth and maxillary traits. The author discusses the structural similarities and distinctions between these new genera and other known families of pelycosaurs, such as the Nitosauridae and Sphenacodontidae. Additionally, Fox offers insights into the geological context of the Fort Sill locality, proposing that the accumulation of skeletal remains within fissures likely resulted from transportation by water rather than being solely the result of predation. Overall, the publication enhances the scientific understanding of pelycosaur diversity and their ecological dynamics during the early Permian period. (This is an automatically generated summary.)
