While at a local Barnes & Noble the other day, I saw a book I had heard about last year (published in September). It's "Beasts before Us: The Untold Story of Mammal Origins and Evolution (Bloomsbury Sigma, 2021). I leafed through it and it looks like a good read if you're into the evolution of terrestrial land vertebrates and specifically, synapsids.

Identification: This tooth was found in processed microfossil matrix from Waurika, OK, USA. Reptile remains in general are very uncommon, so if you think you've found many pieces of Dimetrodon teeth, you're likely mistaking many Orthacanth shark cusps. Orthacanth shark enamel is smooth, and the serrations are quite prominent compared to those on Dimetrodon which are finer. Dimetrodon enamel is not smooth, as seen on this one. Dimetrodon crowns are also broader. Shark cusps broken at the foot of the crown also flare out, where reptile teeth do not. Were this crown complete, you would also not

From the album: Permian
Dimetrodon sp. Wellington/Ryan Fm., Waurika, OK, USA Post-canine/posterior tooth This tooth is likely from D. limbatus, given the locality and presence of serrations: https://www.nature.com/articles/ncomms4269 The same paper also rules out other serrated Sphenacodonts by the enamel ornamentation. Its smaller size could indicate that it's from a juvenile. It differs from the comparatively abundant broken Orthacanth shark tooth cusps in the microfossil matrix (what most people are likely to confuse with): the enamel texture is not smooth, the c -

I can't find any pictures that focus on Edaphosaurus claws, and I can't zoom in enough on pictures to get a clear visual of any claws, so I can't see any differences between Dimetrodon and Edaphosaurus claws are. They're both really small compared to the bodies, so it's hard to see from full body/skeleton pictures, and they wouldn't be from enough angles to be sure. Someone who has dealt with lots of them, including on articulated specimens, has said that they're almost the same, and as far as he knows, but isn't 100% sure about it, the biggest difference, the only one he is aware of, is that

Hey everyone, this is for anything Sphenacodont--dimetrodon, or otherwise. Collections/pictures/discussions/whatever. This is the splinter thread off of the sphenacodont collections thread, so if anyone would like to bring over anything from the other thread, please feel free. I'm going to bring over some interesting posted info that covered different topics, and with links to interesting and useful info. *some discussions covering other things and animals in relation to sphenacodonts is perfectly fine. For instance, spinosaurus, Permian topics, apex predators, or whatever. As long

Hey gang here is a quick shot of a good day- finally getting Bonnie the Dimetrodon out of the quarry and into the museum. 8 months of digging and preparing for this big move. The weight is right at 6000 pounds. Next stage is getting her opened up and prepped. In the quarry we have 2 more skeletons to start on. Dang I love the Permian.
