Cretodus crassidens
A LARGE, High Quality Cretodus crassidens, an extinct Mackerel shark, tooth from Dallas Co., Texas. An excellent example of this Lower Cretaceous Eagle Ford Fm. tooth. These massive teeth have a design that includes a large / heavy root with high root face, a narrow crown width, and broad side cusps. This is the big shark tooth in Texas Cretaceous deposits which can reach 2.6". This is an anterior tooth with perfect side cusps. Authenticity guaranteed. I don't see many of these teeth.
