I found these two last weekend in North Carolina. Found in Upper cretaceous, Black Creek Formation.
One is from a carnivore and the other from a herbivore. I haven't been able to get home from work for better photos taken outside, sorry. I also have all my scales and such packed away at the moment. The herbivore tooth is 3/4" including the root. The carivore tooth is just over 1/2". I have an idea one the herivore but will wait to see what more knowlegeable folks have to say.
If you need photos from other angles let me know. Thanks for looking!
