Biostratigraphy type relative dating technique Web camera sex online without registration

Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists used this technique to determine ages of materials.

This allows the dating of much older and smaller samples but at a far higher cost.

For each dating or chronological method there is a link in the box at right to take you to that section of this page.

There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.

However, human beings love to see factual precision, and we want to know how old something is.

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.
