Chronometric methods include radiocarbon, potassium-argon, fission-track, and thermoluminescence. The most commonly used chronometic method is radiocarbon analysis. It measures the decay of radioactive carbon (14C) that has been absorbed from the atmosphere by a plant or animal prior to its death.

What dating technique is used by paleontologists?

What is one technique that scientists use to date the fossils they find? Potassium-argon dating is a form of isotopic dating commonly used in paleontology. Scientists use the known natural decay rates for isotopes of potassium and argon to find the date of the rocks.
