Coprolite
What is Coprolite?
Coprolite is the fossilized feces of animals. It provides valuable insights into the diet and environment of extinct creatures. Coprolites vary in size, shape, and composition depending on the animal that produced them and the environment in which they were preserved. They are often found in sedimentary rocks and can contain undigested food remains, such as bones, scales, and plant matter. The study of coprolites, known as coprology, helps paleontologists understand the evolution of animal diets, the ecosystems of the past, and the behavior of ancient animals.
