Hello helpful fossiliers, Help please. These fossils came from outside Moab close to the Colorado River, but on a high shelf. The river is not visible from this location. Roadside Geology of Utah identifies this area as Permian, as did a BLM paleontologist. They are from about 10-15 miles SW from Moab. The rocks are largely a red base (clay?) with a gray-er surface. These three pictures are actually 3 different locations on the rock, but I think (wonder if) they are the same life form. The first is about 2 mm long. The ruler shows a mm scale. You can see the cross section end of the item on the fossil closest to the ruler. The second is a round disc from elsewhere on the surface and the third is a connected series of round discs. My sense is that the disc and connect discs are crinoid segments. Is the first picture also a crinoid, or am I way off on all this? I can post additional pictures if anyone asks. Thanks. Tom

Seed-plant fossils Found in Late Permian strata of Jordan

This particular species had spines attached to the shell which is not all that common. There are four spines attached on the thumbnail brachiopod. The holes in the shells were where spines used to be attached. Found during this trip here:

Here is a hungry boy from the Permian that I drew.Not yet sure if I like the way I drew the sand clouds, and I think that using pen for the final product was definitely a mistake, but otherwise it is okay.

If anyone is familiar with Permian tracks, can anyone ID these? All I can tell is that they appear to be synapsid tracks, but not Dimetrodon. I'm assuming that means Edaphosaurus is out too, but that's all I can figure. the ONLY details still known are that they're Permian tracks from somewhere in Arizona. There's no more information available. There's 4 plates... 1-pic 1 2-pics 2,3,4 3-pics 5 4-pics 6,7

Taxonomy from Werneburg 2021. Diagnosis from Werneburg 2021, p. 36ff: "The combination of following characters differs from most other branchiosaurids: (1) Very short maxilla, without contact to short jugal (persisting gap between maxilla and cheek up to adult stage, shared with Schoenfelderpeton). 22 teeth of maxilla are only few more than of premaxilla (16). (2) Parietals elongated and very narrow, like the width of frontals (shared with Schoenfelderpeton, Melanerpeton pusillum, Leptorophus raischi). (3) Prefrontal and postfrontal in contact (shared with Branchiosaurus). (4) Small orbita (shared with Schoenfelderpeton). (5) Wide intraorbital region (IOw/Sl about 0.29-0.37, shared with Branchiosaurus commentryensis, Apateon caducus and A. flagrifer). (6) Tooth base is relatively wide in earliest stage (shared with eryopiformes). (7) Parasphenoid with elongated basal plate and narrow cultriform process in adult stage (shared with Branchiosaurus salamandroides, Schoenfelderpeton, Leptorophus raischi). (8) Choana very wide in adult stage (shared with adult Apateon caducus). (9) Dentary with pleurodont dentition. (10) Hyobranchial skeleton of kontheri-type (shared with Branchiosaurus commentryensis, Apateon kontheri and A. pedestris). (11) Early ossification of exoccipital starting with skull length of 7 mm. Exoccipital relatively high, with a wide shaft, especially wide anteromedial ends and sculpture of longitudinal ridges. (12) Small growing species (shared with both species of Branchiosaurus, Apateon pedestris, A. flagrifer, Melanerpeton pusillum, and M. arnhardti)."
