Why dating of fossils is inaccurate

Rated 4.55/5 based on 708 customer reviews

Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.

Most scientists today believe that life has existed on the earth for billions of years.Despite the obvious significance of this site, poor dating techniques have prevented scientists from recreating the entire global evolutionary picture of ancient species.This is because the fossils have been dated using what is called “relative dating”, where fossil age is determined by comparing it to fossils and rocks that have already been dated.The age they came back with was only a few thousand years old. And kept their theory that dinosaurs lived "millions of years ago" instead. They then use potassium argon, or other methods, and date the fossils again.This date did not fit the preconceived notion that dinosaurs lived millions of years ago. They do this many times, using a different dating method each time.
