Fossil - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

A fossil is the preserved remains, imprint, or trace of a once-living organism that lived thousands or even millions of years ago. They are often found in rocks and can include bones, shells, or even the footprints of ancient animals and plants. Fossils give scientists clues about what life was like in the past, helping us understand how different species have evolved over time. By studying fossils, we can learn about extinct creatures, like dinosaurs, and see how the Earth's environment has changed throughout history.
