Coprolite Fossil Collection | Three Pieces of Fossil Poop

This is a collection of three coprolites; fossilized poop from the Pleistocene age over 10,000 years ago. Exact ID of the animal which left them is unknown. These types of specimens often contain bone fragment such as snake vertebrae, fish vertebrae, gar fish scales, etc, which leads me to believe that these may often be from alligators.
