12" Xiphactinus Jaw Section With 7 Teeth - Kansas

This is a fearsome jaw section of the huge, predatory fish, Xiphactinus audax. It's 12" long and was collected from the Smoky Hill Chalk of Gove County, Kansas. One can imagine how terrifying of a predator this fish must have been given is huge, dagger-like teeth.

There are 7 teeth still present in the jaw section with the largest being 1.35" long. There is are a few crack repairs but no restoration and the teeth are original.



Xiphactinus was a huge, predatory fish that lived during the Late Cretaceous. It would have been a veracious predator, growing 15-20 feet long. When alive, the fish would have resembled a gargantuan, fanged tarpon.

Xiphactinus has appeared in the BBC's Sea Monsters and National Geographic's Sea Monsters: A Prehistoric Adventure as well as being labelled a "Prehistoric Terror" in River Monsters.
