nathan.dugan Posted October 9, 2021 Share Posted October 9, 2021 Hello, Just purchased some Permian matrix bags from Richards Spur, OK and the Texas Red Beds. I have a few items I'm wondering if anyone can help me ID. I do have some guesses for a few of them. Using a dime for scale. Red Beds Going to guess Eryops skull fragment on this one. I think these might be fragments of Orthacanthus spines. Partial vert? This one is so small I really can't capture any distinct detail in the photo. Most small teeth fragments in this matrix were the broken tips of Orthacanthus teeth. However this is much rounder (although I can make out at least one edge), has no serration as far as I can tell, and under a very bright light I can see extremely fine vertical ridges (striae?) down the length of the tooth. It is also colored differently. Not hoping for much on this guy but my best guess would be some sort of amphibian. This one I'm fairly confident is an Archeria "jaw"; I understand they would have had some kind of palate plate to help grasp/swallow prey? More info on that would be awesome. It definitely matches what I've seen on Google. Richards Spur, OK Am very interested in this one in particular. Some kind of rooted tooth, it has this strange acorn shape to it. Not seen anything like it elsewhere. Thanks for having a look and my apologies for the poor photos; all I've got is a magnifying glass. I think I need to buy a book so I can try and identify this stuff on my own! Link to comment Share on other sites More sharing options...
Ludwigia Posted October 9, 2021 Share Posted October 9, 2021 I don't know anything about Permian fossils, but I just wanted to warn you that Coco is going to jump on you in a minute Greetings from the Lake of Constance.

Coco Posted October 9, 2021 Share Posted October 9, 2021 Your pictures are small, but maybe a Texan or someone who knows this sediment can help you. In addition to the origin and age of the terrain in which the fossils are found, size is also important for proper identification. Coins are not a good indication of the scale, only Americans know the size of your coin and we are a forum where many members live all over the world. I invite you to read my last link in my signature. If you don’t have a rule, print the document I made available and put your fossils on it before making your photos, making sure to leave a box with the apparent size (pedagogical message ) Coco ---------------------- OUTIL POUR MESURER VOS FOSSILES : ici Ma bibliothèque PDF 1 (Poissons et sélaciens récents & fossiles) : ici Ma bibliothèque PDF 2 (Animaux vivants - sans poissons ni sélaciens) : ici Mâchoires sélaciennes récentes : ici Hétérodontiques et sélaciens : ici Oeufs sélaciens récents : ici Otolithes de poissons récents ! ici Un Greg...

Titan Posted October 10, 2021 Share Posted October 10, 2021 Cool stuff! I’m more familiar with early Permian than late but I think you’re correct on number three, it looks like a partial archeria vert to me. The last tooth might be a Diadectes premolar? It’s a lot smaller than the ones I’ve seen but if so it’d be a nice find. Link to comment Share on other sites More sharing options...

More info on that would be awesome. It definitely matches what I've seen on Google. This is probably parareptile or Seymouria. Definitely not Archeria.
