fossils-uk Posted March 25, 2022 Share Posted March 25, 2022 Hey guys, I obtained this tooth at tucson this year direct from the finder. It is from the Judith river formation, hill county, montana. 2.2cm long. got a characteristic V shaped flattened area on each side of the tooth, which i have seen in nanotryannus but it can't be that ? as nano doesnt occur in the judith river.... or it's has been mislabelled? My question is tyrannosaurid or dromeosaurid? if so what could it be? thanks for your time. @Troodon 1 Link to comment Share on other sites More sharing options...

Troodon Posted March 25, 2022 Share Posted March 25, 2022 Thank you. My call on this tooth is that its from a juvie indeterminate Tyrannosaurid. Its a lower right anterior tooth. Also a bit large for a Dromaeosaurus tooth. Link to comment Share on other sites More sharing options...
