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. absolute dating is the numeric age of a layer or rocks of fossils A mold fossil is dissolved by underground water and it has no internal structure. The type of rock that most fossils are found in A fossil is the remains of an animal that existed millions of years ago in a specific type of rock. When an animal or a larger species dies out. Cast fossils are created by the hollow spaces of a mold that is later filled with mineral matter. a paleontologist finds fossils or studies fossils and where they came from, what animal they were, etc. radiometric dating is getting an age for geologic materials or measuring the age of geologic materials. relative dating is the age of the rock layer compared to other layers A fossil record is a timeline or history that is composed of by fossils.
