  1. From the album Permian era fossils

    Reverse side of the unidentified Edaphosaurus pogonias bone with an apparent Dimetrodon tooth hole.
  2. 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.
  3. 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.
