Relative dating of geological strata
However, relative methods are , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. However, geological strata are not always found to be in a neat chronological order.
Wind and water erode strata and some areas are uplifted or even tilted.
As a result, it was difficult to chronologically compare fossils from different parts of the world.It had been cleverly carved to fit the skull and stained to look ancient.In addition, the associated bones from extinct animals had much older fluorine and nitrogen ratios than either the jaw or the human skull.However, the assumption of contemporaneity may not always be correct.This is due to the fact that one or both of the objects may have been moved or redeposited into a different location.
