It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.
The most common relative dating method is stratigraphy.
The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly.
This principle presumes that the oldest layer of a stratigraphic sequence will be on the bottom and the most recent, or youngest, will be on the top.But, how can we determine how old a rock formation is, if it hasn’t previously been dated?Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks.
Scientists find out the age of a dinosaur fossil by dating not only the rocks in which it lies, but those below and above it.Index fossils are fossils that are known to only occur within a very specific age range.
