Today, scientists use a variety of techniques to date rocks and fossils precisely . Most often, they measure the amounts of particular radioactive elements—often radiocarbon or potassium—present to determine when a rock was formed, or when an animal or plant died . Some techniques work best with materials millions or even billions of years old .
It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers . Therefore, some discovered fossils are able to be dated according to the strata, a distinct layer of rock , that they are found in . Another common way that fossils are dated, is through radiocarbon dating .
There are two main methods determining a fossils age, relative dating and absolute dating . Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages .
Unlike relative dating methods , absolute dating methods provide chronological estimates of the age of certain geological materials associated with fossils , and even direct age measurements of the fossil material itself . To establish the age of a rock or a fossil , researchers use some type of clock to determine the date it was formed .
Nowadays, several well-established techniques are available for dating biological remains, e .g . radiocarbon, dendrochronology, and amino acid racemization techniques for wooden structures or tools . . .
There are also other radiometric dating methods that are used to date strata and fossils . One of the most common is the potassium-argon dating method . This is used to date volcanic rock to the time the volcano erupted . If this rock is above a fossil , that fossil can be dated as "older" than the volcanic rock above it .
Methods of Dating Fossils . We have learnt how fossils are formed over geologic timescales . In this section we will learn how we determine the age of a fossil . There are two methods of dating fossils : Radiometric dating ; Relative Dating ; 1 . Radiometric Dating . In order to understand radiometric dating , it is necessary to revise our understanding of the atom .
Paleoanthropological methods : Dating fossils "Archaeologists will date any old thing" (Jim Moore, UCSD) Taphonomy: study of processes of fossilization (literally, "laws of burial"; study of diagenetic processes acting on a dead animal's remains) . Diagenesis: sum of the physical, chemical, and biological changes affecting a fossil -bearing sediment;
Example of Dating Assumptions Find a fossil with a measured ratio of 16 trillion to 1 (C12 to C14) This means 4 half-lives have expired giving a date of about 23,000 years 8 trillion to 1 : 1 half-life instead of 4 - age 5,000 What if the ratio started at: 2 trillion to 1 : 3 half-lives instead of 4 - age 17,000
Third, magnetism in rocks can be used to estimate the age of a fossil site . This method uses the orientation of the Earth's magnetic field, which has changed through time, to determine ages for fossils and rocks . Citation: Peppe, D . J . & Deino, A . L .
