The type of rock that most fossils are found in absolute dating is the numeric age of a layer or rocks of fossils A fossil is the remains of an animal that existed millions of years ago in a specific type of rock. A mold fossil is dissolved by underground water and it has no internal structure. 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. The Law of Uniformitarianism is used to explain the history of past events on Earth because it's the idea that the same physical laws of today have always existed. A fossil record is a timeline or history that is composed of by fossils. When an animal or a larger species dies out.
