Polished Fish Coprolite (Fossil Poo)
This is a rather unusual fossil, it is a coprolite (fossilized poop) from a large fish. These coprolites are Carboniferous (350 million years old) and possibly came from the prehistoric lobe-finned fish, Megalichthys. The coprolite has been cut in half and highly polished. Many of these show signs of the fishes meal such as fossilized scales when examined closely.
