Serratolamna lerichei

An attractive Mackerel shark tooth with side cusp development. These teeth are very showy. Beautiful examples are included below. Eocene in age - approx. 55 million years ago. Teeth sold in a set of 2 teeth - except for the new extra large collector's teeth. Have a look at the new teeth. These are the largest S. lerichei teeth that I have ever seen. Extra large sized!
