Radiometric dating

Absolute dating relies on the known rate of decay of radioactive elements present in the rock to arrive at a fairly precise age. For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating. This evaluation of the rocks and fossils in relative dating is known as the biostratigraphy. Relative dating is achieved by determining the position of rock in strata, and the appearance of certain index fossils.
