Clues from Fossils Fossils give us information about living things in the past.
What Can you learn from fossils? Scientists use clues from fossils to learn about the past.
How Fossils Form When a plant or animal dies, the soft parts quickly decay. Hard parts are left behind. teeth bones shells
Sedimentary Rocks Most fossils are found in sedimentary rocks. The remains are quickly buried by the sediments.
Imprints Sometimes a shallow print or impression is the only evidence that a animal or plant ever existed.
Molds Shells often leave behind fossils known as molds. It is a hollow form with a particular shape.
Molds A mold forms when water seeps into the rocks where a shell is buried. The water dissolves the shell, which leaves a hollow space where the shell once was.
Cast A cast is formed or shaped in a mold when minerals slowly accumulate in a mold. They take the shape of the original shell and form a copy.
