Here is a gorgeous display plate of a natural, non-dyed specimen from the Green River Formation. This piece is a little lighter than some of the more recent specimens we have added to our gallery. The dark and light difference between the two individual fish really adds to the uniqueness of this piece.
Knightia sp. is an extinct genus of freshwater bony fish that thrived in both North America and Asia during the Eocene Epoch (56 to 33.9 million years ago). This Epoch took place during the Paleogene Period. This genus was first described in 1907 and is closely related to herrings and sardines. This is the state fossil of Wyoming and is considered the most commonly excavated fossil in the world.
This fist had thick scales with conical teeth. Some of the largest specimens discovered have measured up to 10-inches long, but averages around 3 to 4 inches long. This genus was low on the food chain, often schooling and being preyed on by larger fish such as Diplomystus sp., Lepisosteus sp., Mioplosussp., and Phareodus sp.
