The oldest fossils in the fossil record date from 3.5 billion years ago, however it wasn't until around 600 million years ago that complex, multi-cellular life began was first preserved in the fossil record. Body fossils provide more information because not only they tell us about their activity, but also about their anatomy and body function. A fossil that shows an intermediate state between an ancestral trait and that of its later descendants is said to bear a transitional feature.

A trace fossil, also ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity but not the preserved remains of the plant or animal itself.
