Fish Coprolite #3
This is a piece of fish coprolite (fossil poop) from the Niobrara Chalk of Western Kansas (Cretaceous 70-80 MYA). Although coprolites are fairly common, nice specimens like this with bone present are not often found. This piece measures about 1 1/8" long and about 3/8" diameter. This piece contains several small fish bones. See pictures for details.
