Hexanchus griseus - Sixgill Cow shark

This catalog contains excellent shark teeth from the highly sought after Cow sharks, Notorhynchus primigenius, a Sevengill Cow shark and the ultra rare Hexanchus griseus, the Sixgill Cow shark. These Cow shark teeth exhibit wide rectangular root that is topped with a saw-like row of six cusps. The Cow shark family is fairly rare and exceptional specimens are hard to locate. The Notorynchus teeth are Miocene age found in the Pungo River Formation (15 million years old) from the Lee Creek mine in No. Carolina and are among the finest known Miocene Sevengill Cow shark examples. The Hexanchus teeth are Pliocene age from the Yorktown Formation. This is the best group of Cow shark teeth that I have seen in a long time!
