JamieLynn Posted July 14, 2022 Share Posted July 14, 2022 I was supposed to go to a Permian site in Oklahoma when the Paleontological Society of Austin went a few months ago, but I came down with a cold instead! Yay..... So, my friend brought me back a bag of dirt! Because I love a good bag of dirt! My friend warned me that they didn't have a lot of surface finds, so I wasn't really expecting much, but I was happily surprised by the finds! The color on these fossils is my favorite part- gorgeous reds and purples! I know what most of the finds are, but there are a few unknowns, so if anyone can ID, I'd be thankful! Also, if I mis-ID's any thing.... All of these are about 3-6mm except the vertebra Amphibian Trimerorhachis insignis 1. 2. Amphibian Eryops 3. 4. not sure about this one. I don't think it's Eryops. 5. I'm not sure what this is - a claw? 6. a decent sized vertebra - 1/2 inch 7. Orthocanthus compresus 8. 9. 10. I think this is shark cartiledge 11. A bit of bone? 12. And I have no idea what this is....a denticle perhaps? 13. 5 www.fossil-quest.com Link to comment Share on other sites More sharing options...
siteseer Posted July 14, 2022 Share Posted July 14, 2022 I think #9 and 10 are pieces of xenacanth shark head spines. 1 Link to comment Share on other sites More sharing options...
JamieLynn Posted July 14, 2022 Author Share Posted July 14, 2022 @siteseer - Thanks! looks like I might have one of each. I wasn't aware of the difference till I looked it up just now and found this thread: www.fossil-quest.com Link to comment Share on other sites More sharing options...
ThePhysicist Posted July 14, 2022 Share Posted July 14, 2022 1,2. Fish teeth, there's a thread somewhere that discusses these 3. Amphibian, could be Eryops 4,5. Given the smooth enamel, could be Orthacanth cusps 6. I'm just seeing bone, is there a clear blood groove on each side? (compare:) 7. I've seen ones like these referred to Archeria, but can't say anything with confidence 8. O. platypternus - one cusp is significantly smaller than the other, and they have very flat roots ^ https://geojournals.pgi.gov.pl/agp/article/download/10334/8846 11. Agree, Orthacanth cartilage 12. bone 13. Is it flat? Looks like a fish scale 2 "Argumentation cannot suffice for the discovery of new work, since the subtlety of Nature is greater many times than the subtlety of argument." - Carl Sagan "I was born not knowing and have had only a little time to change that here and there." - Richard Feynman Collections: Hell Creek Microsite | Hell Creek/Lance | Dinosaurs | Sharks | Squamates | Post Oak Creek | North Sulphur River | Lee Creek | Aguja | Permian | Devonian | Triassic | Harding Sandstone Instagram: @thephysicist_tff Link to comment Share on other sites More sharing options...
JamieLynn Posted July 14, 2022 Author Share Posted July 14, 2022 @ThePhysicist Thanks for the help! No, I do not see a blood groove which made me wonder if it was indeed a claw. It literally looks just like the claw sheath that my cat sheds....like the husk of a claw. And yes, the fish scale is flat. That makes sense it being a scale. www.fossil-quest.com Link to comment Share on other sites More sharing options...
jdp Posted July 15, 2022 Share Posted July 15, 2022 I think 6 is a piece of scale. Might be a different element but the conchoidal fracture on the surface suggests it's dentine. 7 is an embolomere of some sort. Might be Archeria. Might not. What formation is this? 12 looks like it might might might be a partial diplocaulid vertebra. Would want to see it from other angles and with a scale bar. 2 Link to comment Share on other sites More sharing options...
