This catalog contains beautiful teeth from the narrow-tooth Mako shark - Isurus desori. These teeth are noted for their narrow, straight crown. The Sharktooth Hill site produces very nice I. desori teeth which occur in much less frequency than the I. hastalis or I. planus. We are offering some good quality I. desori teeth. This catalog contains a group of I. desori teeth with great color and preservation. Note - some of these teeth are from a very narrow form of Isurus hastalis and may not be the classic I. desori teeth - unique! Examples of Temblor and Olcese teeth included.
