Fossil palm & fish 2

Product description

This plate is from the Green River Formation, Wyoming, USA.


The palm and fish are Eocene, 50 million years old.


Although fish are common from this formation, palms are rarer, and as such command higher prices, particularly when fish are included.


The catastrophic event that overcame the fish and palm must have occurred extremely quickly (such as a mud slide), because you can still see the direction of the water flow (right to left) in the fronds of the palm


The fish are Diplomystus (hunter) and Knightia (prey)


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, such as the two Knightia displayed on the same plate.


The smaller fish, Knightia, were common, and were unfortunate enough to be the prey of most of the other fish that existed at that time.
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 fossilised fish in the world.
During the Eocene the region was sub tropical to temperate.
The size of this plate is 25" x 35" x 1.5" thick.
