FISH PLATE GREEN RIVER
On offer is a beautiful multi-fish and palm plate, from the world famous Green River Formation, Wyoming, USA.
It dates from the Eocene Period, and is 50 million years old.
This is a large and extremely well preserved specimen with two fish, a Priscacara and a Diplomystus, plus the added bonus of an inclusion of Palm leaves.
Priscacara (meaning `primitive head') was shaped rather like a sunfish and had sturdy dorsal fins, probably to protect it from being swallowed from behind by predators.
It was a predatory fish, hunting the smaller Knightia.
The preservation, particularly on the dorsal fin of this piece, is superb.
This is one of the rarer fish from the Green River Formation
Diplomystus is distantly related to modern herrings, and was a surface feeder, as shown by their upturned mouths, and body shape.
They fed on smaller surface dwelling fish
50 million years ago a lake existed in what is now Wyoming, with a size of around 930 square miles. The unusual chemistry of the lake prevented decay and the scavenging of the dead organisms, while thin layers of alternating limestone and organic matter slowly accumulated.
The resulting limestone beds contain the highest concentration of fossillised fish in the world.
During the Eocene the region was sub tropical to temperate.
A piece of "Fossil Art" for display in the home, or office.
