Multiple Specimen Mortality Plate
A museum quality Priscacara, surrounded by a school of Knightia fish make this mortality plate a true showpiece. We were lucky enough to meet with the discoverer of this awesome specimen before anyone else and instantly purchased it. Several others were a bit envious, but hey, that's the way it goes! The freeform shape of the piece adds to its natural aesthetic composition. Also, the plate is already laminated with wood on the back to allow for a hanging cleat. However, we'll include a display stand, in case you'd like to set it on a shelf, table, etc.
Plate Measurements: ~19" long x 20" tall x 1-7/8" thick
Location: Green River Formation, Wyoming
Time Period: Eocene ~50 Million Years Old
The Green River Formation in the USA covers an area over 25,000 square miles and is more than 2,000 feet thick. This formation, dates back more than 50 million years. It is one of the largest documented accumulations of sedimentary rock in the world. At the time, the area was sub-tropical and many different species flourished. Today, the majority of Fossil Fish taken out of this limestone formation are from two separate layers. "The 18" layer and the split fish layer". The 18" layer is composed of laminated sheets of limestone, allowing for fossil fish specimens to be extracted whole.
Priscacara (common name perch) is a member of the Family Prisca Caridae. The name Priscacara means "primitive head." The two Priscacara species are liops and serrata. Priscacara liops is the more common and the smaller of the two. The genus became extinct at the end of the Miocene period, and is thought to be related to the modern-day Cichlidae.
