Fossils

Fossils are the time capsules of the Earth — preserved remains and traces of organisms that lived millions of years ago, unearthed from rock layers and sedimentary beds. In this section you’ll explore how fossils form, what they tell us about past life and environments, and how scientists use them to reconstruct Earth’s history.
