Larger 50 Million Year OLD! Diplomystus FISH Fossil on BIG Matrix Wyoming 1191gr

Hello, here is a Larger Diplomystus Dentatus Fish fossil in its BIG 50 Million Year Old Green River Formation Matrix! This fossil was quarried in an extinct lake that is known as Fossil Lake in Lincoln County, Wyoming and dates from the Eocene epoch a CRAZY 53.5 to 48.5 Million YEARS ago!
Here's More Info Long but Interesting....Fifty-million years ago an ancient Lake existed in what is now Southwest Wyoming, US. The unusual chemistry of the lake created conditions that prevented decay while alternating layers of limestone and organic matter accumulated. The resulting laminated limestone LAYERS contain the highest concentration of articulated fish fossils in the world....neat! 
The fish measures around 6 3/8" or 16.3cm and the overall piece or matrix measures a BIG 10.25" or 26.3cm at their biggest or from opposing side to side. Please note that a Display STAND is included.
