Compare techniques for dating fossils. These processes also exposed the fossils buried within those layers of layers of volcanic rock are extremely important to reconstructing the history of the turkana basin because they allow scientists to calculate the age of hominin fossils found in the region.
It is impossible to give an evolutionary sequence to the human fossils because there is a coverage gap involving the dating methods which evolutionists believe are the most reliable—radiocarbon and potassium-argon (K-Ar). This gap is from about 40,000 ya (years ago) to about 200,000 ya on the evolutionist's time scale.

At this stage, you will be starting to see that the dating of human fossils has quite a few limitations. Now add to this the fact that many of the fossils that we currently have were excavated or discovered at a time long before we developed careful excavation processes that include not only the recovery of the fossil but also the collection and cataloguing of corresponding site materials.Learn More
Suppose you find a fossil at one place that cannot be dated using absolute methods. That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age. Some of the most useful fossils for dating purposes are very small ones.Learn More
