Isurus escheri - Serrated Mako

Buried Treasure Fossils offers Isurus escheri teeth for sale, a very rare and unique serrated Mako shark tooth. Isurus escheri is a late Miocene age shark that evolved from Isurus hastalis and has the added characteristic of 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. Have a look.
