JamieLynn Posted May 25, 2021 Share Posted May 25, 2021 Hello all! A batch of new unknowns found in my micro matrix! Any help will be appreciated! Cretaceous Eagle Ford formation. 1. Interesting geometric pychnodont tooth? I know they can be rectangular, but this one is oddly shaped. Size 5mm 2. Strange "fat" tooth". It looks sharky but the width of the base is throwing me for a loop. Perhaps the cusplet of a bigger tooth? Size 5 mm 3. An odd striated tooth. Size 6 mm 4. A very pointy something. I thought it was a Scapanyorhynchus tooth at first, but it's not quite right. Seems more "fishy". Size 6mm 7. Not even sure what to make of this. It has bone texture, but also other stuff? Size 8mm 8. A weird little double pointy thing. Those two sticky up "stalks" are just strange. Size 2 mm 9. Thinking this might be turtle? Very small though. Size 12mm 10. Lastly, a little vertebra that might be snake Size 7mm 1 3 www.fossil-quest.com Link to comment Share on other sites More sharing options...

Bronzviking Posted May 25, 2021 Share Posted May 25, 2021 Nice micro collection! #1 looks like a drum fish tooth. Link to comment Share on other sites More sharing options...

And the unknown one has a weird "zig-zag" to it. www.fossil-quest.com Link to comment Share on other sites More sharing options...
gturner333 Posted May 26, 2021 Share Posted May 26, 2021 #1 looks like a pseudohypolophus ray tooth. Need to see a side view to be sure. 1 1 Link to comment Share on other sites More sharing options...
ThePhysicist Posted May 26, 2021 Share Posted May 26, 2021 1. Pseudohypolophus mcnultyi. Welton and Farish say this species is distinguished from other Texas rays by their hexagonal crowns. 2. I'm thinking this is a cusplet as well. Probably no way to say for sure from what, but its shape is reminiscent of goblin. 3. goblin symphyseal 4. goblin symphyseal - I haven't seen a rooted fish tooth like that 5. not seeing anything... 6. not seeing anything... 7. really rough Squalicorax sp. 8. Dunno, could be bryozoan covered in stuff, or just geologic 9. Not seeing any bone here, could be a rock... 10. Need more views.

JamieLynn Posted May 26, 2021 Author Share Posted May 26, 2021 hahahah!! My numbering is pretty sad.....completely skipped over 5 and 6. Ah well. Here are a few more views of vert. It is a bit roughed up.: www.fossil-quest.com Link to comment Share on other sites More sharing options...
ThePhysicist Posted May 26, 2021 Share Posted May 26, 2021 Not sure about the vert. @Harry Pristis "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...
jikohr Posted May 26, 2021 Share Posted May 26, 2021 I think the vertebrae is a Pleistocene snake/lizard vertebrae. Pleistocene stuff gets washed into post oak creek all the time. That would be my guess at least. 1 Link to comment Share on other sites More sharing options...

JamieLynn Posted May 27, 2021 Author Share Posted May 27, 2021 A question...could it be a coniasaur? I swear I saw a picture of a coniasaur vert online but now I can't find it anywhere. It looked very similar from what I remember (but that could just be because it is reptile). I found a coniasaur tooth and I know they have been found in the POC. www.fossil-quest.com Link to comment Share on other sites More sharing options...

Just a rough guess as I hadn't been studying bones yet. 1 Link to comment Share on other sites More sharing options...
