Diplomystus dentatus was an extinct surface-feeding fish with a distinctive upturned mouth, adapted to feed on small fish like Knightia, often preserved in its stomach or mouth. This herring-like fish lived in Fossil Lake, located in present-day southwest Wyoming, around 50 million years ago.

Fossil Lake, once covering up to 930 square miles, preserves exceptionally fossil-rich laminated limestone, preventing decomposition and capturing a complete Paleogene freshwater ecosystem. Fossils include fish, amphibians, turtles, alligators, birds, mammals, plants, insects, and crustaceans. Terrestrial surroundings are represented by horses, snakes, lizards, bats, and over 325 plant species.

This Eocene fossil site offers the most comprehensive record of freshwater lake life, making Diplomystus dentatus and its ecosystem invaluable to science.

Please be aware of the nature of fossils:

Being buried underground for millions of years under immense pressure can be quite harsh. Rarely is a fossil found completely intact and perfect. Many fossils require some form of restoration, and some are even modified by humans to improve their appearance. These features are part of the fossil's natural charm and are not seen as flaws.
