Detailed, 8.5" Priscacara Serrata - Green River Formation

This is a large, 8.5" long specimen of Priscacara serrata from the Green River Formation of Wyoming. It was collected from Warfield's Quarry near Kemmerer Wyoming this past summer. It comes with a display stand or we can add a backing and wall hanger to the piece for a small additional charge.

Priscacara is an extinct, genus of temperate bass that lived during the Eocene. It is an uncommon species in the Green River Formation, representing less than 1% of the total fish fossils. It is a favorite among fossil collectors, particularly those specimens with all of their dorsal spines pointing upwards. It can occasionally reach impressive sizes in excess of 16 inches in length. Priscacara has a large mouth and impressive array of teeth can often be seen in detail on larger, well-preserved specimens.

Priscacara is more frequently found in shoreline lake deposits and less frequently found in rocks deposited in the center of the lake. It's appearance is very similar to that of Cockerellites, a genus of schooling fish found in large numbers in the mid-lake quarries. Cockerellites maxed out in the 5 to 6 inch range, so specimens larger than that are assumed to be Priscacara. Cockerellites have more dorsal and anal fin rays than Priscacara and a significantly smaller mouth.
