Absolute dating can provide a more precise date than relative dating, but it can be expensive and time-consuming, while relative dating is more cost-effective and efficient.By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as “bracketing” the age of the sedimentary layer in which the fossils occur. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.

First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon-14 isotope. Radiocarbon dating has been used for ...Researchers can first apply an absolute dating method to the layer. 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 Taupo volcano erupted in A.D. 232. Anything below the Taupo tephra is earlier than 232; anything above it is later.
