4.3" Fossil Xiphactinus Jaw Section - Smoky Hill Chalk, Kansas

This is a jaw section of the huge predatory fish, Xiphactinus audax. It's 4.3" long and was collected from the Smoky Hill Chalk of Gove County, Kansas. The teeth have broken away for the most part, with the mineralization of their interiors (pulp cavity) visible. One tooth can be observed where the bone has chipped away from the jaw.

It comes with an acrylic display stand.



Xiphactinus was a huge predatory fish that lived during the Late Cretaceous. It would have been a voracious predator, growing 15-20 feet long. When alive, the fish would have resembled a gargantuan fanged tarpon. It appeared in the BBC's Sea Monsters and National Geographic's Sea Monsters: A Prehistoric Adventure, and was labelled a "Prehistoric Terror" in the Animal Planet show River Monsters.
