Any trace of an animal or plant that lived a very long time ago.
Any remnant of an animal or plant that lived in a past geological age. Fossils can be impressions in sediments that preserve the shape of ancient life, the mineralized remains of bones, or preserved whole organisms in ice or amber. The change and development of species revealed in the fossil record is key evidence for the evolution of life.
