Xiphactinus (Cretaceous Monster Fish) Vertebrae & Ribs - Kansas

This is a really cool fossil from the Smoky Hill Chalk in Gove County, Kansas. There a large vertebrae and several ribs of the prehistoric, monster fish Xiphactinus still partially embedded in it's original chalk matrix. It was collected in Gove County, Kansas and nicely prepared to expose the fossil bones.

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.

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.
