Place of discovery: Russia, Samara region, Sok river.

i found this along the coast of gerringong along with some spiriferida fossils, i have absolutely no idea what it is and also sorry for the bad photos my phone cannot do any better

Howdy! I'm looking to purchase these plates of Discosauriscus from the Permian of Moravia, Czech Republic. They are from the limnic deposits. There is supposedly no repair or restoration. Thank you.

Hello, I was hoping someone could let me know if these fossils are genuine Dimetrodon from Archer County, TX Nocona Formation. Thanks!

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. But one group of terrestrial survivors of the extinction event which would have a massive ecological impact in the Mesozoic are the Diapsida or the Diapsid reptiles. The Diapsids emerged during the Pennsylvanian stage of the Carboniferous era 302 Million Years ago and includes the Archosaurs. This resilient group not only survived the extinction event but experienced a rapid period of diversification during the Triassic and gave rise to the non-avian dinosaurs, the crocodilians, and eventually the avian dinosaurs the birds. Luckily for all of us, this remarkable group continues to thrive today. Here’s a list of all currently known Diapsid reptile 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.

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.

Now this will really sadden me if it's fake. It's a Permian Period Captorhinus reptile from Lawson, Oklahoma. Please give me some good news.

Found digging in luther, oklahoma known area for Permian concreations and horn coral fossils. Item found was cemented in sandstone after soaking for 6 months and powerwashing with 3300psi this is results.
