This is my first post, so please bear with me. I found this tooth this summer in the Rendonda formation in Quay county New Mexico. This should date it to the late Triassic, 202-204 mya. The area where it was found contains almost exclusively Phytosaur fossils, but I am 99% certain that this one is not. It measures about 2.5 cm in length and has one edge with fine serrations. Based on the general shape and serrations, I am guessing some sort of theropod, however I do not know enough about other crocodilian species such as Postosuchus to rule something like that out. Any help would be appreciated, and if you need more pictures/information, feel free to let me know!
