  1. 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?
  2. Dimetrodon sail spine pieces

    From the album Permian era fossils

    Very small fragments of dimetrodons sail spines. From the lower Permian Texas Red Beds, Archer city formation in Archer county
  3. From the album Permian era fossils

    Reverse side of the unidentified Edaphosaurus pogonias bone with an apparent Dimetrodon tooth hole.
  4. Edaphosaurus with large predator bite

    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.
  5. 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:)
  6. Dimetrodon tiny teeth

    What is the deal with dimetrodon teeth??? I see them for sale regularly, but they're always MICRO! I even see some still teeny tiny labeled as "large" and "huge"? Even the super rare and expensive ones I've only ever seen a few of, are still less than an inch. Same with claws. I KNOW they have much bigger teeth, and claws, so why are practically dust particle size teeth&claws the only ones found? I know there's many dimetrodon species, but most of them are decent size. At LEAST big enough that even large juveniles should have notably larger parts. Ive never read anything that said that babies/newborns are almost all that's ever found. In fact(this just crossed my mind as im typing) I see sail sections regularly, that all clearly come from adult sized animals. I don't think Ive ever even SEEN small or baby sized sail fragments that come from animals anywhere near as small as all the teeth Ive ever seen. those smaller teeth in these pics may look small in those giant heads, and many pics make them appear smaller cause it's from a side view and the jaw obstructs the lower part of the back teeth from the side. The super rare and expensive teeth Ive seen only a few times ever, were comparable to the smallest teeth in those pictures. And the average size teeth and claws I see are literally fractions of a centimeter. The bottom picture is the average claw size that I see all the time--those dishes are 1.25"!!!!!! in fact, teeth and claws are in those vials of micro-fossils from sifted site debris. whats going on with my 'metros???

  8. fish/reptile jaw section?

    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.
