Carbon dating is used to determine the age of biological artifacts up to 50, years old. Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. Correlation is, as mentioned earlier, the technique of piecing together the informational content of separated outcrops. Lake Turkana has a geologic history that favored the preservation of fossils.

There are two types of age determinations.
Radiometric datingradioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbonin which trace radioactive impurities were selectively incorporated when they were formed. Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The most widely known form of radiometric dating is carbon dating. Archaeological finds worldwide have helped researchers to fill out the story of human evolution and migration. What are the two methods of dating rocks and fossils And the persians probably used to estimate dinosaur weight.
