The rejection of dating by religious fundamentalists is easier for them to make but harder for them to demonstrate the fossils occur in regular sequences time after time radioactive decay happens and repeated cross testing of radiometric dates confirms their validity.

Figure 2 how relative dating of events and radiometric numeric dates are combined to produce a calibrated geological time scale in this example the data demonstrates that fossil b time was somewhere between 151 and 140 million years ago and that fossil a.

Before more precise absolute dating tools were possible researchers used a variety of comparative approaches called relative dating these methods some of which are still used today provide only an approximate spot within a previously established sequence think of it as ordering rather than dating.

radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.

Carbon dating is used to determine the age of biological artifacts up to 50000 years old this technique is widely used on recent artifacts but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.
