It can only be used to types of dating methods fossils younger than about 75,000 years. So, often layers of meyhods rocks above and below the layers containing fossils can be dated to provide a date range for the fossil containing rocks. Scientists can use certain types of fossils referred to as to assist in relative dating via correlation. Since the rock formation contains both types of fossils the ago of the rock formation must be in the overlapping date range of 415 to 420 million years. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it. Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. Typically commonly occurring fossils that had a widespread geographic distribution types of dating methods as brachiopods, trilobites, and ammonites work best as index fossils. If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil. This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time. metjods In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between 410 and 420 million years. The same rock formation also contains a type of trilobite that was known to live 415 to 425 million years ago. For example if you have a and it was found in the Wheeler Formation. This uses radioactive minerals that occur in rocks and fossils almost like a geological clock. The atoms in some chemical elements have different forms, called isotopes. In this relative dating method, terms and are usually used to indicate both the oldest and the most recent possible moments when an event occurred or an artifact was ttypes in a.
