Fossilized animal excrement embedded in rock.
Coprolite - Fossilized excrement of vertebrates, a good source of information about the food sources of extinct animals.
This is the official name for fossilized dung, which is exactly what it looks like. Most of the coprolites are from alligators, but they may be from nearly any animal. Sometimes other small fossils, the remains of what the animal had eaten, are found inside the coprolite.
Preserved dung which allows researchers to learn about the diets of humans from ancient times.
Fossil dung or feces. Typically these are preserved in arid environments such as as dry caves or sand dunes.
Preserved poop. By examining coprolites under a microscope, scientists can see things such as seeds, pollen grains, pieces of bone, and parasite eggs. These things can tell archaeologists a lot about the diet and health of people and animals in the past.

Coprolite is the name given to the mineral that results when human or animal dung is fossilized. The name is derived from the Greek words κοπÏος/kopros meaning 'dung' and λιθος/lithos meaning 'stone'. It serves a valuable purpose in archaelogical and anthropological circles because it provides a picture of an early organism's diet and environment.
