Dating skeletal remains
But if they are earlier than 1485, then they can’t be Richard’s remains.Radiocarbon dating is a commonly used technique which relies on the fact that, although 99% of carbon atoms have six protons and six neutrons (carbon-12), about 1% have an extra neutron (carbon-13) and about one atom in a trillion has two extra neutrons (carbon-14).Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects.
This applies the geological principle that under normal circumstances younger layers of sediment will be deposited on top of older layers.

Since the time of separation of the evolutionary lines of apes and humans about 5 million years ago, some fossil specimens of the skeletal remains of our earliest ancestors have been preserved and discovered.
Four main methods have been used in Willandra archaeology.
This well known method was the first technique that became available for accurate dating of old materials.
