WHAT IS A FOSSIL 4 A fossil is the remains or traces of a living thing This can be a plant insect or animal The remains are preserved in rock Fossils take thousands of years to form Some take millions Fossils are important They tell scientists about what life was like long ago Scientists can learn how plants and animals have changed Some fossils form through petrification This is when minerals enter the remains Conditions must be just right for petrification to occur PETRIFIED FOSSIL
FOSSILS IN AMBER 5 The remains need to be buried quickly Then minerals fill spaces in the remains The minerals harden the remains into a fossil Fossils can also be found in amber And some fossils are molds These are impressions from the preserved remains MOLD FOSSIL
