HOW ARE FOSSILS FORMED?

Most fossils are formed when a plant or animal dies in a watery environment and then is rapidly buried in mud and silt. The soft parts of the plants and animals break down leaving the hard bones or shells behind. Over time, small particles called sediment build up over the top and harden into rock.  These clues of the remains of these animals and plants are preserved for scientists to find thousands of years later.  These type of fossils are called body fossils. Sometimes only the activity of the plants and animals are left behind.  These types of fossil are called trace fossils.  Think about footprints, burrows, trails, food remains etc. ALSO CHECK OUT: Salt Dough Dinosaur Fossils Some other ways fossilization can happen is through rapid freezing, being preserved in amber (the resin of trees), drying, cast and molds and being compacted.
