jpc Posted December 23, 2020 Share Posted December 23, 2020 I agree with this IDs. except... 5 looks like a sawfish tooth. 7, I also dont know, but I do not find these in the Lance or Hell Creek 8. need more views. Is this the one you showed in a separate post that I IDed as a mammal premolar? 9, yes these are the little cusps on the edge of the tooth 11... I think I see out of focus serration on this one. Cool strange tooth indeed. Fun stuff. 2 Link to comment Share on other sites More sharing options...

Guns Found a couple of pieces of small hadro teeth and small dino bone fragments, but no theropod. Still have some more stuff to look through (really fine matrix though). Probably will get more matrix eventually (got 4 lbs to start). There haven't been many complete descriptions of the fauna in Aguja, so the crocodilian teeth you have can be cf.
