Two New Pelycosaurs from the Lower Permian of Oklahoma

"Two New Pelycosaurs from the Lower Permian of Oklahoma" by Richard C. Fox is a scientific exploration into the discovery and classification of two previously unknown pelycosaur genera from the early Permian period in Oklahoma. The publication details the identification of *Delorhynchus priscus* and *Thrausmosaurus serratidens*, focusing on their physical characteristics as derived from fossilized remains, particularly their teeth and jaw structures. These observations further provide insight into how these creatures relate to other pelycosaur groups, like the Nitosauridae and Sphenacodontidae families. Moreover, the work contemplates the geological factors of the Fort Sill site, suggesting how water transport may have played a role in concentrating the fossilized bones within fissures.
