Knightia

Knightia is an extinct genus of freshwater fish that lived in the lakes and rivers of North America and Asia during the Eocene epoch. It was discovered by David Starr Jordan in 1907. Knightia is Wyoming's state fossil, belonging to the same taxonomic family as herring and sardines. It likely fed on algae and diatoms, as well as smaller fish and insects.
