Methods of dating fossils

More information
When a new fossil is discovered, geologists assign a date for when they think the plant or animal lived. They normally use radiometric dating methods to date the fossil, and many promote these methods as being accurate. Yet when you look into the technical papers on these discoveries, you find that these dates are often questionable and are sometimes clearly in error. Several types of radiometric dating methods are used today. One of the best known is carbon 14 C

Slideshows Videos Audio. Here of some of the well-tested methods of dating used in the study of early humans: Potassium-argon dating , Argon-argon dating , Carbon or Radiocarbon , and Uranium series. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. Thermo-luminescence , Optically stimulated luminescence , and Electron spin resonance. All of these methods measure the amount of electrons that get absorbed and trapped inside a rock or tooth over time.

Geologic Dating Methods: Are They Always Accurate?

Two major dating methods applied to artifacts and fossils are stratagraphic dating based upon the particular layer of rock of sediment in which the object is found or radiometric dating which is based on the decay rates of certain radioactive isotopes. The type of radiometric dating used depends greatly on the approximate time period you are studying and so varies depending on if the material you are studying is an artifact or a fossil. The method most commonly used in archaeology is carbon dating. Carbon dating is only effective for time periods less than 70, years. This excludes all the major index fossils, and is a very short geologic time span.

Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.
