Description

Green River- Diplomystus fish (260207f)

Species: Diplomystus sp.

Age: Eocene Epoch, 53 million years

Formation: Green River Formation

Location: Kemmerer, Wyoming

The Green River Formation is made up of the remains of an ancient lake bed crossing multiple states, which 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 are perhaps most similar to modern-day trout or tuna, quick with large mouths to eat knightia, or even other smaller diplomystus. This particular piece comes from the “18-inch” layer of the quarry, known for the darker coloration of the fossils produced there. This layer is also a bit more durable, allowing these larger specimens to be extracted usually in one piece.

•  Fish has been sealed and stabilized in the original matrix and has NOT been inlaid. The sealant used for this task appears to have darkened the fish slightly, but this is a normal procedure and will keep the fish from flaking away over time.
