All About Fossils

Fossil


Fossils are dead animals or plants.They are usually skeletons found embedded in rock.sometimes fossils are footprints or poop.


Small animals or insects get stuck in tree sap which hardens and traps them forever.Large animals can get stuck in ice or their carcass gets trapped in layers of rock.Over thousands of years,pressure builds up and the skeleton is dissolved by water under the ground.Next the mould left is filled with minerals that from rock.This rock shape is the fossil - an exact replica of the dinosaurs.This process tacks 10,000 years.Palaeontologists find fossils when the top layers of dirt washes away.
