Palaeontological dating definition

, in which figures in solar years (often with some necessary margin of error) can be applied to a particular event.

Unless tied to historical records, dating by archaeological methods can only be relative -- such as stratigraphy, typology, , fluorine and nitrogen test, and radiometric assay.

The 14C decays to the nitrogen isotope 14N with a half-life of 5730 years.

Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its agea technique for determining the age of minerals based on the occurrence in natural rubidium of a fixed amount of the radioisotope 87Rb which decays to the stable strontium isotope 87Sr with a half-life of 5 x 1011 years.

Most of these techniques produce results with a techniques do not.This term refers to the relation of one stratigraphical unit to another, by petrological, osteological, lithographic, cultural, chronological, or palaeontological means.For example, stratigraphic units may be correlated using palaeontological criteria, methods, and position relative to the glacial-interglacial cycle by examining physical and biological attributes.Other methods include: coin dating, seriation, and amino-acid racemization.The methods have varying applications, accuracy, range, and cost.
