Fossilized “Green River” Fish (251119m)
Green River Formation Diplomystus Fossil Fish with Crocodile Coprolite
- Age: Eocene Epoch 53 million years
- Formation: Green River Formation
- Location: Kemmerer, Wyoming
Green River is the remains of an ancient lake bed that dried up millions of years ago. The lake contained hundreds of different species, ranging from the most common Knightia to gars, freshwater rays, and even crocodiles and bats, which flew overhead.
Diplomystus is a large fish similar to a trout in many ways though there are also several differences. This specimen comes from the 19inch layer were oils often turn the remains a very dark brown or even black coloration. This is completely natural and is unstained. The plate itself has been sealed and backed with wood to allow for durability and lets you mount the piece on a wall more easily if you wish.
The true star of this piece however is the large crocodile coprolite in the bottom left corner, while perhaps less impressive than the fish, the coprolite is a much rarer find. You can even make out the remains of crushed bones of other fish, perhaps even other diplomystus within to coprolite. This creates an excellent snapshot of life in Green River.
