Hi all!
Got another tooth here I'm looking for help on ID with. Only unfortunate thing is the exact county is unknown. Bought from an older collection so all the seller knew for sure is Hell Creek Formation. Seller has been very cooperative and is also very interested if an ID can be found with that little caveat. It was labeled dakotaraptor from the old collection. Initial thought was R. gilmorei or nano but doesn't look to have the defined nano pinch. No mesial serrations visible or can be felt. Best picture he could get of the serrations is below as well. Appreciate any input! Thanks!
