Fossilized feces reveal insights into Earth’s early ecosystems and biodiversity

Why fossilized feces from ancestors of modern animals help us understand Earth’s early ecosystems

A study of fossilized feces, known as coprolites, from 540 million years ago found fecal matter likely played a significant role in an explosion of biodiversity in the early Cambrian period. Paleontologists say these fossils can tell us a lot about ancient animals and the ecosystems they inhabited.
