Carbon 13 isotope dating

Radioactive dating is often illustrated with an hour glass.

The sand grains at the top of the sealed glass are like the atoms of the parent isotope in the rock, and those at the bottom like the atoms of the daughter.

Normally a good scientist will be curious about the ages of important fossil bones,” Mr Miller told Ancient Origins in an email.

The unstable potassium isotope is called the parent while the argon product is called the daughter.

There are a couple of different radioactive forms of uranium that decay into lead.

The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.

The Museum, which has since 2005 been in cooperation with the Paleochronology Group, a team of consultants in geology, paleontology, chemistry, engineering, and education, sent a sample of the outer portion of the Triceratops brow horn to Head of the Paleochronology Group Hugh Miller, at his request, in order to carry out Carbon-14 dating.

There are many different radioactive isotopes that are used for radiometric dating.

For example, there is a radioactive form of potassium (potassium-40) that decays into argon (argon-40).Each element comes in different forms, called isotopes, most of which are stable and do not change.Some isotopes, however, are unstable and decay radioactively into other elements.There is a radioactive form of thorium that also decays into lead.There is an isotope of samarium that decays into neodymium, and one of rubidium that decays into strontium.Scientists never considered it worthwhile to run the test since it is generally believed that dinosaurs have been extinct for 65 million years, based on radiometric dating of the volcanic layers above or below fossils, a method which the Paleochronology Group states has “serious problems and gross assumptions must be made”.
