How Do Scientists Date Fossils?
Dating fossils using radioisotopes is the modern method for estimating the age of ancient things. As a recent Public Broadcasting Service PBS program illustrates, there are good reasons to question any age dating theory, including date estimates using radioisotopes. While the practice of dating fossils has long been popular, the methods and results have historically been controversial.
Morris ( ) talks about methods used to date fossils. He claims that “... fossils are not dated by the rocks in which they are found; rather, the rocks are.

Figure 1. Paleoanthropology , a subdiscipline of anthropology, is the study of extinct primates. While the majority of researchers doing this kind of work are anthropologists, paleontologists within the discipline of geology may also study fossil primates. The primary method used by paleoanthropologists is the analysis of fossil remains. However, they increasingly rely on other scientific disciplines to gain a better understanding of the environmental forces that played a role in our evolution, as well as the formation of the fossil record.
Though still heavily used, relative dating is now augmented by several Radiocarbon dating involves determining the age of an ancient fossil or antler or one of many other carbonates may be dated using this technique.

Dating Fossils in the Rocks
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
They then use that absolute date to establish a relative age for fossils and artifacts in relation to that layer. For example, New Zealand’s massive.
Potassium-argon dating , method of determining the time of origin of rocks by measuring the ratio of radioactive argon to radioactive potassium in the rock. This dating method is based upon the decay of radioactive potassium to radioactive argon in minerals and rocks; potassium also decays to calcium Thus, the ratio of argon and potassium and radiogenic calcium to potassium in a mineral or rock is a measure of the age of the sample.
The calcium-potassium age method is seldom used, however, because of the great abundance of nonradiogenic calcium in minerals or rocks, which masks the presence of radiogenic calcium. On the other hand, the abundance of argon in the Earth is relatively small because of its escape to the atmosphere during processes associated with volcanism.
The potassium-argon dating method has been used to measure a wide variety of ages.
