The name Priscacara translates as ‘primitive head’ and is possibly the most common fish fossil found at Green River. The priscacara has two different species within, the liops and the serrata, although the serrata are less common. They are believed to have been extinct at the end of the Milocene period. The fine quality of the preservation of these fossils is thought to be due to the cold period which sank the dead fishes quicker and the depth of the lakes prevented other predators from swimming down and eating the carcasses.
