Ginsu Shark Teeth

Enter the “Western Interior Seaway” with our selection of authentic Ginsu Shark teeth. Formally known as Cretoxyrhina mantelli, this apex predator of the Late Cretaceous was the “Great White” of its time, reaching lengths of up to 25 feet. These fossils are instantly recognizable by their broad, smooth-edged crowns—which were so sharp they earned the shark its “Ginsu” moniker—and their robust, deeply bifurcated roots. Sourced primarily from the world-famous Niobrara Chalk of Kansas and the phosphate deposits of the Southeast, our Ginsu fossils are hand-picked for their elegant symmetry and glass-like enamel. Own a piece of the predator that dared to hunt the giant marine lizards of the prehistoric Midwest.
