13.1" Predatory Mioplosus Fossil Fish - Wyoming


This is an detailed, 13.1" long example of Mioplosus labracoides from the Green River Formation of Wyoming. It was collected this summer at the Fossil Lake Safari Quarry near Kemmerer. Very nice detail including fins, scales and bone structure with good preparation work

It's nicely centered on an unbroken, 16.6x10" slab of shale. We can back the slab and add a wall hanger at no additional charge 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).
