Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past. This fossil record shows that many kinds of extinct organisms were very different in form from any now living. It also shows successions of organisms through time see faunal succession, law of ; geochronology: Determining the relationships of fossils with rock strata , manifesting their transition from one form to another. When an organism dies, it is usually destroyed by other forms of life and by weathering processes. On rare occasions some body parts—particularly hard ones such as shells, teeth, or bones—are preserved by being buried in mud or protected in some other way from predators and weather. Eventually, they may become petrified and preserved indefinitely with the rocks in which they are embedded.

Uncertain ages

Timothy Clarey, with a Ph. Since the middle of the 20th century, secular scientists have claimed to be able to make determinations of absolute time using radioactive isotopes of certain elements. Commonly used radioactive elements are isotopes of uranium, thorium, rubidium, strontium, argon, and potassium. Most of the time, only igneous rocks are analyzed. Sedimentary rocks may contain the proper radioactive elements, but they are usually mixtures of rock types from various locations and therefore give mixed ages if analyzed.
