bobobob Posted December 13, 2017 Share Posted December 13, 2017 Here is a fossil carnivore (I assume) that I purchased with no information at an online auction. I know little about fossils but the double pair of incisors seems odd to me. Or maybe they are not incisors. I assumed this is a mammal but maybe not? Hopeful for an identification and any information; thanks. I can post more detailed photos if necessaary. Link to comment Share on other sites More sharing options...

Fossildude19 Posted December 13, 2017 Share Posted December 13, 2017 This looks like an oreodont skull, from the White River Formation. Could the "2" incisors actually be one that split?

jpc Posted December 13, 2017 Share Posted December 13, 2017 caterpillar is right, not a carnivore. And he should know. he has a few in his collection. This is an oreodont skull. Common plant eating mammal from the White River Formation (about 35 million years old) of South Dakota, Nebraska, Wyoming etc. I can't tell if the double 'canine tooth' is truly double is simply split down the middle which is common, even in modern animals after they die. I think it is split. you are correct, though; it is not a canine, but is often called that. It is the last incisor, which is greatly enlarged (=caniniform) in oreodonts. This is probably Merycoidodon culbertsoni edit: Looks like Tim and I were saying the same thing at the same time. Link to comment Share on other sites More sharing options...
Fruitbat Posted December 13, 2017 Share Posted December 13, 2017 bobobob... Welcome to The Fossil Forum! +1 in the oreodont skull camp. With a little work that looks like it might be a very nice specimen. -Joe Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
bobobob Posted December 13, 2017 Author Share Posted December 13, 2017 Thanks so much. This is really a great site. Glad I found it . I've had this oreodont for several years but it didn't occur to me it could be IDed online. Yes, the incisor is indeed split, since the other side is single. I should have looked at it more carefully; but even so I would not have guessed that the one had split. Here are photos of both sides. I've got a few other fossils around here that I will gradually post as well. Best regards to all, bobobob Link to comment Share on other sites More sharing options...
