Absolute Dating Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods. This light can be measured to determine the last time the item was heated. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization. The Wheeler Formation has been previously dated to approximately million year old, so we know the trilobite is also about million years old. The amount of luminescence released is used to calculate the equivalent dose De that the sediment has acquired since deposition, which can be used in combination with the dose rate Dr to calculate the age. Each ring represents one year; the outside rings, near the bark, are the youngest.
