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