Cast fossils are created by the hollow spaces of a mold that is later filled with mineral matter. A fossil is the remains of an animal that existed millions of years ago in a specific type of rock. A fossil record is a timeline or history that is composed of by fossils. The law of superposition says each layer of rock is older than the one after or above it, so the further down into the rock layer you go, the older the layers become. A mold fossil is dissolved by underground water and it has no internal structure.
