This small Diplomystus dentatus has good bone preservation in dark reddish brown, I found in the 12” or split fish layer of fossil lake. It is on matrix that is approximately 4-1/4” x 3” x 3/4” shipping and packaging is included in the price.
The second most common of fish fossils in the Fossil Lake representing approximately 25-30% of all fossil fish found. Diplomystus is one of the only Green River Formation species to spawn mid-lake and do most of their hunting nearshore on the fry of smaller fish species. They can often reach lengths of over a foot in length, maxing out around 2 feet long.
