DESCRIPTION:
This sale is for a great Knightia fossil fish in 50 million year old Green River Formation matrix! 
Fifty-million years ago an ancient lake existed in what is now Southwest Wyoming. The unusual chemistry of the lake created conditions that prevented decay and scavenging, while alternating layers of limestone and organic matter accumulated. The resulting laminated limestone contains the highest concentration of articulated fish fossils in the world. 
The photographs speak for themselves and you can see that the quality of preservation is absolutely superb. This fossil has not been enhanced, the shape of the fish has not been altered / painted / artificially made to stand out. It's completely natural, as it was found.

PLEASE note that a new display STAND is included FREE.

 

MORE INFORMATION ABOUT KNIGHTIA FOSSIL FISH spp:
Knightia Eocaena is the most common fish in Fossil Lake and may be the most common articulated vertebrate fossil in the world.  It is Wyoming's State Fossil.  Length:  up to 25 cm (10 in). Fifty million years ago ancient Fossil Lake existed in what is now southwest Wyoming.  Of its estimated maximum extent of 930 square miles, approximately 500 square miles of sediment remains.  The 230 square miles across the center of the ancient lake-bed contain exceptionally fossiliferous sediments and associated geologic features including deltas, beaches, springs, and rocks from the centre and nearshore environments.

The unusual chemistry of fossil lake prevented decay and scavenging of dead organisms while millimetre-thick layers of alternating limestone matter slowly accumulated.  The result is laminated limestones that contained the highest concentration of fossil fish in the world.  These fish, other aquatic organisms, and associated geologic features make Fossil Lake the world's best Paleogene record of the freshwater lake ecosystem.
