Isurus escheri

This catalog contains exceptional teeth from a very rare and unique Mako shark - Isurus escheri. Isurus escheri is a late Miocene age shark that evolved from Isurus hastalis and added characteristic very fine serrations to the cutting edge. The serrations are much finer than those of the Great White transition teeth that are found in Chile and elsewhere. The Isurus escheri is a dead end lineage that disappeared early in the Pliocene. These teeth were collected in "De Kuilen" sand pit, Mill, The Netherlands. Age is late Miocene (approx. 6-8 million years ago). The teeth from the Mill come in varying quality. I have a small group of exceptional teeth to offer from this rare species that are complete and well preserved. This may be the best offering of Isurus escheri teeth that you will ever see. Authenticity guaranteed.
