Overview

An EXTRA LARGE, High Quality Ptychodus mortoni, an extinct durophagous (shell-crushing) shark, tooth from Dallas Co., Texas. An excellent example of this Upper Cretaceous Eagle Ford Fm. tooth. These teeth have a design that includes a high cusp with radiating occlusal ridges extending across the cusp face. Authenticity guaranteed. P. mortoni is a rare species in Texas, and when teeth get this large they are extremely rare! The last of my largest teeth.
