4.1" Xiphactinus Pre-Maxillary Bone With Tooth - Kansas

This is an awe-inspiring, pre-maxillary bone from the "Terror fish of the Cretaceous seas", Xiphactinus audax. It was collected from the Late Cretaceous, Smoky Hill Chalk Member of the Niobrara Formation in Kansas. The pre-maxillary section of the jaw sits front and center on the upper jaw and contains three or more massive teeth. It is a really cool piece of the jaw that isn't often highlighted. The girth of this bone is astonishing. This specimen is extra awesome because it has a partial tooth protruding from the front of it.

Comes with an acrylic display stand.

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. It 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.

The Smoky Hill Chalk Member of the Niobrara Chalk formation is a Cretaceous conservation Lagerstätte, or fossil rich geological formation, known primarily for its exceptionally well-preserved marine reptiles. It outcrops in parts of northwest Kansas, its most famous localities for fossils, and in southeastern Nebraska. Large well-known fossils excavated from the Smoky Hill Chalk include marine reptiles such as plesiosaurs, large bony fish such as Xiphactinus, mosasaurs, pterosaurs, and turtles.
