Description AVERAGE SIZE: 147mm All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity! Name: Diplomystus sp. Species: Fish Age: Eocene Period Location Found: USA Diplomystus is a prehistoric genus of freshwater clupeomorph fish that was present in the Eocene period, around 56 to 33.9 million years ago. They are distantly related to modern-day extant herrings, alewives, and sardines, and like them their strongly upturned mouths suggest that they fed in open water rather than feeding off the bottom. Diplomystus are often found in association with other Eocene fish from the Green River Formation, particularly the genus Knightia. In fact fossil evidence suggests that Diplomystus preyed upon Knightia! SIMILAR TO SEEN: The image shows an example of the single specimen you will receive.
