fossilsonwheels Posted March 1, 2021 Share Posted March 1, 2021 I’m not really sure I’ll be to get an ID given the condition, size and difficulty in photographing them but I thought I’d try. First tooth. Just over 1mm. This one is from Atco Formation micro mix. There was an Odontaspis on Elasmo that looked somewhat similar but I really don’t know.

fossilsonwheels Posted March 1, 2021 Author Share Posted March 1, 2021 Another tiny, incomplete Atco Formation tooth. No clue. I think it’s Carcharhiniformes but I could be wrong about that. Less than 1mm. Link to comment Share on other sites More sharing options...
fossilsonwheels Posted March 1, 2021 Author Share Posted March 1, 2021 This is one I can’t quite put an ID on from our Mesaverde micro matrix. I am pretty puzzled. I found a Columbusia on Elasmo that is the best match that I’ve so far. Open to any suggestions Link to comment Share on other sites More sharing options...

fossilsonwheels Posted March 7, 2021 Author Share Posted March 7, 2021 Another Atco Formation tooth that I’m not real sure of the right identification. In looking at Hamms paper, I thought perhaps Ginglymostoma but I’m not sure. I don’t think Chiloscyllium as I’ve seen quite a few of those and this just doesn’t look like one to me. Best I could do on the pics. About 2mm. Link to comment Share on other sites More sharing options...
