Priscacara fish fossil in walnut frame
(56-38 million years old)
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.
This fine specimen shows wonderful detail, including the impression of the scales from the reverse side of the body cavity. The dark body serves as a wonderful contrast to the light-coloured matrix.
