Absolute dating fossils

Rated 3.98/5 based on 921 customer reviews

Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.

The best examples are fossils of animals or plants that lived for a very short period of time and were found in a lot of places.There are some radioactive elements in rock that decay by giving off energy and turning into different, more stable elements.This radioactive decay takes place at a constant rate for each radioactive element.There are several reasons why, but the main reasons is that Carbon-14 is a naturally occurring isotope in all forms of life and its half-life is about 5730 years, so we are able to use it to date more "recent" forms of life relative to the geologic time scale.You would need to have access to scientific instruments at this point that could measure the amount of radioactivity in the sample, so off to the lab we go!
