Fossil Fish Priscacara serrataDescription: This 50 million year old, Eocene-Era fossil fish comes from one of the world's famous Laggerstatten, the Green River Formation in Wyoming. A small portion of the fish fossils from Green River exhibits such fine preservation. The significant extent of soft-tissue preservation that makes the site famous is evident in this specimen.

Genus Priscacara is perhaps the most popular of the Green River fish fossils. A member of the Family Priscacaridae, the name Priscacara means "primitive head". Shaped rather like a sunfish, the genus sports sturdy, protective dorsal and anal spines. Among the two species, liops and serrata, serrata is the more uncommon. The species name comes from the diagnostic serrated preopercle. Liops is the smaller species, never exceeding 150 mm, whereas serrata have been found up to 375 mm. The genus went extinct at the end of the Miocene, and is thought by some to be related to the modern-day Cichildae.

Much time went into the preparation of this specimen, with the dorsal and anal spines presented in high relief, much like a fine sculpture, making this a truly stunning display piece
