Learn how archaeologists use poop to learn about ancient civilizations, in this episode of Gross Science from NOVA. Poop fossils are called coprolites; they are very rare because feces are difficult to preserve. When poop is fossilized, whatever else was in the poop is mineralized as well. The composition of coprolites can provide valuable information about ancient people, including what they ate, where they lived, or even how they died. This resource is part of the NOVA: Gross Science Collection.
