Cretoxyrhina mantelli was a large shark that lived about 100 million years ago, during the late Cretaceous period. It is nicknamed the Ginsu shark in reference to the Ginsu knife, since it fed by slicing into its victims with its knife-sharp teeth. Cretoxyrhina was the largest shark in its time and was among the oceans top predators. Fossil records indicate that it preyed on a variety of marine animals including Mosasaurs, Plesiosaurs, bony fish like Xiphactinus, and large turtles like Archelon.
