It's been a long time since I shared some finds- this is a really nice Dimetrodon caudal (tail) vertebra from a medium size ddon. The short, blade-like neural spine is the tell for position. Newest project for us is prepping a 12 foot by 6 foot block containing remains of at least 6 Dimetrodons. Hoping to get it into the lab by April... will start posting photos soon. Best, Chris

I’ve just found this tooth in some Permian micro matrix from the Wellington formation, it is serrated and around a centimeter long. I’m thinking It’s dimetrodon or some sort of other basal synapsid

Hi, I’m considering buying this “dimetrodon claw” and was wondering if it is really a dimetrodon claw. It was found in waurika, Oklahoma, Ryan formation and is from the Permian. I’m not sure how big it is but it looks pretty small. TIA
-
At 8mm, it seems small to me. Any thoughts? From the Texas Red Beds.

Here is a beautiful young Dimetrodon tibia- wonderful thick permian pond clay helps preserve wonderfully. Short back legs much like a horned toad. Watch a horn toad run and you will get the idea of how these guys ran. Fast, but short, bursts of speed for surprise attack.

Dimetrodon teeth have come up lately and I havent posted in a long time. This specimen is grandis species from the Arroyo formation. Older species are smaller and have interesting fluting, something we don't typically see in the later, more advanced guys who also have larger, more robust teeth with coarser serrations.

Dimetrodon tooth?
thelivingdead531 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I’ve been trying to research and go through previous posts all morning, but I still need help. Can this be confirmed as a Dimetrodon tooth or just as Sphenacodontidae? The seller states that it’s from the Ryan formation and found near Waurika, Oklahoma. It appears to be around 1/4 inch long. I know the photos aren’t the best, but all of the sellers photos are pretty terrible. I can definitely see serrations on the tooth. If anyone can help shed some light on this for me I would appreciate it. I know @Bobby Rico has a slight obsession with Dimetrodons, so maybe he can weigh in.

From the album: Permian era fossils
Basioccipital about .5" large vertebra about 3" small vertebra about 1.5" *more info to be posted -
Came across this in my morning twitter readings and my jaw dropped. Did you know that the name 'Bathygnathus' currently has priority over the name 'Dimetrodon' until an opinion on the reversal of precedence is published by International Commision on Zoological Nomenclature ( iczn.org/node/40573). The application is currently in front of ICZN and research is underway to support the proper taxonomic identity of specimens. From what I read its a very slow process but expected to support Dimetrodon. Anyway about all I know so if anyone would like to add to this please do. http://iczn.org/node/40573 The purpose of this application, under Article 23.9.3 of the Code, is to conserve the widely used generic name Dimetrodon Cope, 1878 (SPHENACODONTOIDEA, SPHENACODONTIDAE). The name Dimetrodon is threatened by its senior subjective synonym Bathygnathus Leidy, 1853. The name Dimetrodon has become widely accepted and is in prevailing usage. It is proposed that Dimetrodon be given precedence over Bathygnathus whenever these names are considered to be synonyms.

ID requested: lower permian vertebrate fauna from Texas red beds & Waurika
ziggycardon posted a topic in Fossil ID
Hi! I recently acquired a few new additions to my permian collection, but there are a few pieces of which I am not a 100 % whether they are ID'd correctly, simply because I am not yet knowlegdeable about the material. So I thought it might be a good idea to post the ones I am doubtfull about here, as I know there are a lot of people more knowlegdeable than me who probably could ID them. The first item is a small claw listed as "juvenile dimetrodon limbatus" from the Red Beds, Archer County, Texas, USA I was a bit doubtfull when they said "juvenile" dimetrodon claw, but I got it anyway because it's a very nice permian claw which was an okay price regardless the ID. The second item is a caudal vertebra that was listed as "Edaphosaurus" (from the Archer City Formation, Red Beds, Archer County, Texas, USA) which came as a set along with a piece of sail spine which without doubt belongs to Edaphosaurus. The last items were sold as a collection of "Eryops megacephalus" fossils from the Wellington garbar complex, Waurika, Okhlahoma. From left to right are a piece of skull plate, a toe bone, a piece of dermal armor and a tooth..jpg.55ea96495e8bec4c4e80bfd13ca0d545.jpg)

Hi, looking for some thoughts on identification of a fossil I bought a while ago. This is a fairly well preserved vertebra from an early reptile of some kind. Unfortunately I lost the original label for it so all I can say is that it’s from 300-250 mya, and from a formation in Oklahoma or Texas. I’m not very experienced with Permian stuff, so I’m not sure where to begin. Thanks for any help!

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 Dimetrodon claws are curved on the bottom, like raptor/general theropod claws, while Edaphosaurus claws, equally sharp, are mostly flat on the bottom, like spino toe claws. Is that the case? Does anyone happen to know?

Very small fragments of dimetrodons sail spines. From the lower Permian Texas Red Beds, Archer city formation in Archer county -
I’m definitely no expert on Dimetrodon or Triassic fossils, but Dimetrodon was one of my favorite critters as a kid and still think they’re pretty cool as a big kid. I found a nice claw that’s advertised as Dimetrodon and wanted to make sure it’s actually from that animal. The seller says this claw was found in Northern Texas in the Texas Red Beds formation. It’s 5/8” long. What do you folks think?

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 as it has some relation. Side-tracking is fine, just bring it back home before too long, please. Here's a link to the previous thread. It would be greatly appreciated if you post pictures of any dimetrodon/sphenacodont fossil material you have:)

Ok I also think it is time for us to see more of the members collections . So without further ado show us your Sphenacodontidae collection . is an extinct family of small to large, advanced, carnivorous, Late Pennsylvanian to middle Permian pelycosaurs. Sphenacodontid fossils are so far known only from North America and Europe and have one of the most ironic creature ever to have lived in there ranks, Dimetrodon. And a claw from the same location.

Hi all, I’m about to purchase this nice set of Dimetrodon vertebrae from the Texas Red Beds. Just wondering if they are in fact Dimetrodon verts? Thank you! Jojo

Heres a really wonderfully scary maxilla from a Dimetrodon grandis from a few days ago. Maxillary fang is killer... This one is nicknamed Annie. She's an isolated specimen. This is one maxillae of 6 were working on, the rest in the field currently.

Hi everyone- quick post of a massive Dimetrodon post canine. The root is attached which is really nice. Have a large ddon skull nearby with an empty socket that this may go to. size is 3 inches. Still have a little bit of matrix to remove.

Hey everyone, here is a really gorgeous axis vertebra from a Dimetrodon. The ultra wide neural spine holds incredible neck muscles.

Hey gang heres another beautiful specimen from this week- wonderful sub adult ddon humerus. Really great bone to show the incredible musculature these guys had on their limbs. very strong animals. Planning on attempting to finish up plastering a block tomorro that contains 3 ddon maxillae and 2 lower jaws, all of which appear to be separate individuals of varied age. cheers chris. and JP i promise not to bleed on any bones tomorro.
