There are many secrets held in Earth's ancient rocks and scientists around the world are continually exposing the remains of past life preserved in the layers beneath the crust. They are called fossils and come in all forms and sizes providing scientists with evidence about the history of life on earth.

Fossils are the preserved remains of plants or animals or their tracks and traces which are preserved in sedimentary rock. For the remains to exist they had to be buried before they completely decomposed or were eaten. Over time more and more sediment covered the remains. In the right circumstances and conditions parts of the animal or plant then turned into fossils.
