Cretoxyrhina mantelli

s catalog contains exceptional teeth from what is thought to be the earliest ancestor to the Mako and Great White sharks - Cretoxyrhina mantelli, the Ginsu shark (an early Lamnid shark). The Cretoxyrhina sharks were among the largest predators of their time and therefore ruled the Cretaceous seas. These teeth were found in the Niobara Chalk Fm. of Gove County, Kansas which was part of the great inland sea area of North America during the Cretaceous (80-90 million years ago). The Cretoxyrhina mantelli makes a great addition to the evolution of the Mako and Great White sharks collection. These teeth are high quality - extra nice condition and preservation. Our biggest and best selection ever of the scarce species!
