fossil record

(redirected from fossil records)

fossil record

the remains of organisms, or traces of their existence (such as footprints), present in the rock strata and forming a history of the development of life from its origins on earth. The record is very largely incomplete due to the comparative rarity with which fossils are formed, but provides evidence of evolution having taken place, particularly where long series of a particular form, such as the horse, can be traced over an extended period of time.
