The Permian-Triassic Extinction event of 252 Million Years (caused by massive volcanic eruptions in what is now Siberia) was one of the biggest mass extinctions in Earth's history (killing 75% of all land genera and 95% of all marine genera). The event marked the end of the Paleozoic and the beginning of the Mesozoic. Famous survivors of the extinction event include the Dicynodont Lystrosaurus, the Therocephalians Moschorhinus, Promoschorhynchus, and the Cynodont Thrinaxodon. One surprising group of terrestrial survivors of the extinction event sometimes overlooked are the Parareptilia, also known as the Parareptiles. The Parareptiles were an ancient group of sauropsids that emerged during the Pennsylvanian stage of the Carboniferous 306 Million Years ago and are a sister taxon to Eureptilia. The Parareptiles reached their ecological zenith during the Permian with some becoming small aquatic predators while others like the Pareiasaurs became 9 foot long, 2,200 lbs herbivores. The Permian-Triassic Extinction Event decimated the group's initial diversity, but a few smaller and more generalist parareptiles survived the event and briefly diversified again before becoming extinct 201.3 Million Years ago at the end of the Triassic. Here’s a list of all currently known Parareptile genera and families that survived the Permian-Triassic Extinction Event. If I forget any examples, please let me know and I'll add the examples to the list promptly.

Hi y'all, I was thinking again about some Permian reptile teeth, I've seen them referred to online as 'parareptile,' but would like collective and/or professional insight. They are pretty distinctive, with a smooth labial face, and a striated lingual face. These are all from Waurika, OK (Wellington fm, Lower Permian). I have several examples, but they're not much different from these two. @jdp @dinodigger 3.5 mm tall: 2 mm tall: They vaguely remind me of a Caseid tooth, which has the same character of the striations/no striations (or I at least think this one is Caseid...). ^ Reisz (2019)
