Hello dear fellow forum members. I acquired an interesting fossil supposed to be an Intercentrum attributed to Dimetrodon. Sellers Info:Lower Permian, Wellington Fm. , Waurika, Oklahoma A forum member informed me that at least in adult Pelycosaurs there should not be a separate Intercentrum. So I am open to your Suggestions- Is it someone elses Intercentrum, is it something completely different? I hope that the structure of the fossil will lead to some ID. Fotos from the seller, because I cannot take better ones at the moment. Sorry for the absence of an exact scale, but you get a general impression of the size. Best Regards, J

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)

Hey all. I recently got back from a trip to the Wellington formation in Oklahoma, and I ended up with approximately 40 teeth. (Most of which were Xenacanthus teeth) I ended up with quite a few bits and pieces I couldn’t identify. To avoid overly cluttering one thread, I will post others later. These three are shown next to cm measurement, and are from the Wellington formation near Waurika Oklahoma. I will provide more photos as needed, it has been overcast and dark so the lighting has been more difficult. Thank you for your time!

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 notice a conical/round depression in the base. This is unlikely to be from another Sphenacodontid based on the locality, presence of serrations, and enamel ornamentation. https://www.nature.com/articles/ncomms4269 Notes: This tooth is a post-canine/posterior tooth, which is the tooth position one is more likely to find in micromatrix since they are smaller.

I've been poking around in some Wellington fm micro matrix, permian age, Jackson Co, OK & thought I found a small worn spiral shell, so I put it with the other items I had pulled out. Later, when looking at the items closer, I realized it wasn't a shell & that I had some slightly crappy matrix... literally. A small coprolite 6 mm in length by 4 mm wide & containing what I think are fish scales. So now I'm digging through the matrix again to see if there is any more. The pics are with a dino lite with no photo stacking software, so please bear with them. This is the one thing I never even considerd that I might find in micro matrix.

"digging" around in some micro matrix from the Wellington fm out of Jackson Co, Oklahoma (Permian age) & found this. Not sure if it's a shell, seed or alien life form. The shell or life form is what I'm hoping (they'll be keepers).. the seed.. probably not so much. Found all sorts of Xenacanthus shark teeth bits along with a few tiny whole ones. But this thing is different. It was sticking out of a bit of matrix that I had to break apart, so I'm hoping it's old & not just some fluke. Only 3 mm in size (ruler marks are in mm), it seems pretty ornamental. Anyhoo, without further delay, the pics.
