Fossil Fish (Mioplosus) With Knightia - Wyoming #161367

This is a large, 13.5" fossil fish (Mioplosus) from the Green River Formation near Kemmerer, Wyoming. This is one of the more uncommon species from the formation. There is also a small knightia associated with it on the slab of shale.

There are a few repaired cracks in the rock. This specimen includes an display stand. We can add a backing and wall hanger to the piece upon request.

Mioplosus is a genus of large extinct perciform fish that lived through the Eocene epoch. This genus is easily distinguished by an elongate fusiform body, double dorsal fins, and forked tail. Mioplosus was a solitary predator with large teeth: a few fossil specimens have been collected with other, smaller fish lodged in their throats. Most fossils of this genus are from the Tertiary-aged Green River Formation in Wyoming, though relatives of this genus are known to range throughout Asia and New Zealand. Mioplosus is also believed to be related to the modern pike-perch of the genus Sander (Stizostedion).
