The more fossilized remains available for study, the more information can be obtained and a more complete understanding achieved.

Scavenger and bacterial activity must be prevented so that decomposition is limited.

Fossils are found in a variety of rock, but most often in sedimentary rock, which forms from the accumulation of sediments.

The replacement of organic materials with inorganic materials is not always complete, as DNA is sometimes preserved within the fossil.

When information derived from two outcrops is integrated, the time interval they represent is probably greater than that of each alone.

Presumably if all the world’s outcrops were integrated, sediments representing all of geologic time would be available for examination.

Response: Niels Stensen created the Law of Superposition, which is the foundation for relative dating methods.

This law states that the youngest objects or layers are on the top, while the older objects and layers are deeper.The DNA can then be analyzed to learn more about the organism.Any living organism can become fossilized, including bacteria, plants, and animals.Radiometric methods, such as radiocarbon dating and radiopotassium dating utilize the regular radioactive decay of isotopes from one form to another.Measuring the ratio of the two forms provides date information.Other relative methods include chemical dating, biostratigraphic or faunal dating, and cultural dating.
