Ptychodus latissimus, DFW
Ptychodus latissimus is a rare species and is better known from Early Coniacian deposits like the Atco. However, they are not unheard of from the Middle Turonian. This fragment of a tooth is extremely low crowned and possesses few very yet thick transverse ridges. It also has a unique margin. I don't think there is any other Ptychodus species that can match this design better than P. latissimus. I've got a couple more potential Kamp Ranch sites circled so fingers crossed I can find a more complete specimen in the near future.
