This catalog contains exceptional upper jaw teeth from the king of the Makos - Isurus hastalis, the Big-tooth Mako shark. These teeth are noted for their wide triangular crown and heavy square roots. The Sharktooth Hill site produces extraordinary I. hastalis teeth. We are offering some the largest and highest quality teeth available with excellent color and preservation. Check out the colors!  

What’s in a name? For the fifty years, Isurus hastalis was known to me and others as the big Mako shark tooth that collectors sought from Miocene – Pliocene deposits. Everyone wanted to find a big Mako tooth. In 2001, Purdy (Smithsonsian) resurrected Isurus xiphodon for the broad-form Mako teeth at Lee Creek. It made sense, but now it is not considered a valid species. In 1964, Glikman proposed the Cosmopolitodus genus for the "hastalis" shark as Isurus hastalis was related to the Great White shark rather than the Mako. This convention was not adopted in the scientific community until the last decade; particularly with the naming of the Carcharodon hubbelli, the Great White transition tooth (late Miocene). There is also a push to rename the shark formerly known as Isurus hastalis to Carcharodon hastalis recognizing that it is an early form of the Great White shark. Ok, Isurus hastalis and Isurus xiphodon names going away, but the future name for "hastlis" appears to be unsettled. What do we call this shark if it is not a Mako? More to come in my Blog article.

Note - all teeth sizes are slant height unless otherwise noted.
