Fossils are a window into Earth ’ s history and the evolution of life. The term fossil literally means something that has been “ dug up, ” but its modern meaning is restricted to preserved evidence of past life.

Such evidence may take the form of. Petrified wood is the most well known result of this process. Petrification takes place in two related ways, replacement and permineralization Plant Fossils The fossilization of plants markedly differs from that of animals.

The leaves are frequently reduced.

Dating Fossils – How Are Fossils Dated?
