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 -
Hi y'all. Found this in some Permian micromatrix from Waurika, OK. There's no way I'm this lucky, but is this a very tiny Dimetrodon claw? I've tried to get access to this paper, but still waiting to see if the authors will send the text. I'm fairly confident it's at least sphenacodontid, based on pictures I've seen on the forum. It's about 3 mm in length. @dinodigger@jdp

Extinct Gaits: How Did Pterosaurs and Synapsids Run?
Sightreader posted a topic in Questions & Answers
Howdy folks, me again with more silly beginner questions... I saw this video of a vampire bat running and wondered if pterosaurs - with their crutch-like folded wings - might have moved in a similar manner? Youtube: Vampire Bat on Treadmill I also saw this video of a Panda cub running. Might synapsids like Dinocephalians or Gorgonopsids - with those weird, “inturned” arms - have moved in a similar fashion? Youtube: Panda Bear Cub Running I’m guessing the answers to both of these questions is probably “no” - I would think that even a slight differ -
This little bone is around 2 cm long and I’d like to know if this specimen shows any indication towards a species. It was found in a set of micro matrix from the Wellington formation, Oklahoma

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

From the album: Permian era fossils
Yet unidentified Edaphosaurus pogonias bone from the Permian era Red Beds site in North Texas, with large unhealed tooth hole from what appears to be a large Dimetrodon's bite, from either the fatal attack, or post-death predation mark. -

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

I bought this a few years ago at a local show. It was mixed in with a bunch of small Otodus and sand tiger shark teeth. I don't remember if the vendor said where they came from and I didn't write it down, but I think Morocco is likely.
