Knightia

Knightia is an extinct genus of clupeid clupeiform bony fish that lived in the fresh water lakes and rivers of North America during the Eocene epoch. The genus was erected by David Starr Jordan in 1907, in honor of the late University of Wyoming professor Wilbur Clinton Knight, "an indefatigable student of the paleontology of the Rocky Mountains." It is the state fossil of Wyoming, and the most commonly excavated fossil fish in the world.
