Accuracy of fossil dating methods
This method has the following restrictions: a) It cannot be used to date items many thousands of years old; b) it can only be used in non-organic materials; and c) the materials to be dated must have been heated to more than 350 degrees Celsius. All of the current dating methods are going through refinement.Archaeologists are seeking an accurate dating technique, but this method is yet to be found.Read More When the Nineteenth Dynasty Pharaoh Menmaatre Seti I drew up the famed King List at his mortuary temple in the holy city of Abydos, he was confident that he had struck the final nail in the coffin of...A team of archaeologists in Egypt have unearthed four ancient child graves at Gebel el-Silsila, the site of a former Egyptian quarry that dates back 3,500 years. A team of archaeologists has announced the discovery of over a thousand stone artifacts, with some of them being up to 1.76 million years old.
It is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between 300 to 10,000 years old.
This process frees energy in the form of light, which can be measured.
By making multiple measurements (you need at least two for a date estimate) we can find out how much radiation the item was exposed to over the years and can get dating estimates related to when the item was last heated.
The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.
The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.
