Coprolite is not classified as a mineral. It is actually the fossilized remains of animal feces, primarily from dinosaurs and other prehistoric animals. These fossils can provide valuable insights into the diets and behaviors of ancient organisms.
While minerals are defined as naturally occurring inorganic solids with a specific chemical composition and crystalline structure, coprolites are organic in origin. They form through a process of fossilization that preserves the shape and sometimes the content of the feces, allowing paleontologists to study them. Thus, they are considered fossils rather than minerals.
