Title: A new varanopid synapsid from the early Permian of Oklahoma and the evolutionary stasis in this clade

General summary: My first paper on an unequivocal crown amniote! I've gone to the dark side... But fear not, the temnospondyls will be back in short order and in force over the next few months! I tagged onto this project that Sigi Maho, our current M.Sc. student, former undergrad, and future med student (sorry if you were looking for a potential Ph.D. student) completed for her undergraduate thesis this past academic year (2018-2019). We described a new species of varanopid synapsid from Richards Spur that's been lying on the back-burner for some time now. For the uninitiated, varanopids are one family of 'pelycosaurs,' a grade of early synapsids that span the late Carboniferous to the middle Permian, and synapsids are the group that gives rise to mammals like us. Don't think that pelycosaurs looked like us though - they include the charismatic, sail-backed Dimetrodon (and the slightly less charismatic but similarly sail-backed Edaphosaurus), the herbivorous caseids (which have stupidly sized head-to-body proportions), and the small, carnivorous eothyridids. You would probably be more inclined to closely associated varanopids with reptiles if you saw one running around today (which is an ongoing debate but not the point of this paper).
