The Fossil Record is the history of life on earth as documented by the remains or imprints of organisms preserved in sedimentary rock. In a few cases the original substance of the hard parts of the organism is preserved, but more often the original components have been replaced by minerals deposited from water seeping through the rock. Priscacara is an extinct genus of perch from the middle Eocene, characterized by a sunfish-like body and stout dorsal and anal spines. Mass deaths of Priscacara suggest it formed schools. This beautiful piece of prehistoric fossil art contains 3 Priscacara.
