ThePhysicist Posted December 17, 2020 Share Posted December 17, 2020 Hey y'all, found what I think may be a Cretaceous mammal incisor. I was hoping to find some mammal teeth when I got the Aguja matrix, but since I haven't found any before, need more experienced eyes. Could very well be a piece of something else. It's about 5mm in length.

digit Posted December 17, 2020 Share Posted December 17, 2020 The real help in identifying it would be a well-lit and well-focused image of the occlusal end (or what may remain of it if it is broken). That is the most diagnostic view for potential mammal teeth. Cheers. -Ken 2 Link to comment Share on other sites More sharing options...
ThePhysicist Posted December 17, 2020 Author Share Posted December 17, 2020 Not sure which is the occlusal end on this guy (guessing the left in the last pic), so captured both (top pic corresponds to left end in last pic of previous post) "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...
digit Posted December 17, 2020 Share Posted December 17, 2020 The rounded end is likely the root end and the flared end is likely the occlusal. That end appears to be broken off as it does not seem to be normal wear. Suspected Cretaceous mammal teeth are well out of my league--perhaps @jpc may have some input? Cheers. -Ken Link to comment Share on other sites More sharing options...
jpc Posted December 17, 2020 Share Posted December 17, 2020 I don't know what this is but it is not a multi incisor. There are too many things going on in it, such as that little sharp ridge I see on the left end of the last photo (first post). Multi incisors also have a definite distinction between where there is enamel and where there is no enamel. This seems to all have the same surface. I don't know how rare they are in the Aguja compared to the Lance/ Hell Creek, but keep looking. Link to comment Share on other sites More sharing options...
ThePhysicist Posted December 17, 2020 Author Share Posted December 17, 2020 Thanks, @jpc, will do!
