Fossils can present clues to how plants and animals lived in the past – what they appeared like, what they ate, what environments they lived in, and how they evolved and went extinct. For lots of of millions of years, the remains of organisms (as well as tracks, trails, and burrows – known as hint fossils) were nearly all of the clues left behind in Earth’s fossil report. A fossil could be studied to determine what sort of organism it represents, how the organism lived, and how it was preserved.
