But really, how do scientists figure out how old their dinosaur bones are?And, what about other findings like fossil fish, plants and insects?Absolute dating relies on the properties of various elements in rocks that over time decompose and may even transform into another element.Also called the “clocks in rocks”, the radioactive isotopes of elements or “parent isotopes” are atoms that decay into new isotopes or “daughter isotopes” where the “parent isotopes” may have varying numbers of neutrons but have the same number of electrons (earthsci.org, 2008).As a member, you'll also get unlimited access to over 55,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Recently, he appeared on the evening news to talk about a new dinosaur he just discovered. Paul says he can tell from the fossils that superus awesomus lived on Earth about 175 million years ago.Paul is super awesome, so I'm going to take him at his word.

I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.

Absolute Dating/Numerical Age Method and How It Is Used to Evaluate Geologic Time The absolute dating or numerical age method approximates the number of years of a given rock, say 200 million years, as compared to relative dating which compares two rocks and merely determines if one is older or younger than the other (earthsci.org, 2008).

The geologic time scale was originally based on relative dating methods but with the development of radioactive dating technology, numerical ages further enhanced the scale.

his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.

It is not about the theory behind radiometric dating methods, it is about their , and it therefore assumes the reader has some familiarity with the technique already (refer to "Other Sources" for more information).
