The answer is that you use radioactive carbon dating to get the dates. But other methods have also been used to date the fossil record.The Fossils Sequence Record It was the study of rock layers in England near the beginning of the 19th century that lead to the study of paleontology and from there to the study of fossils.Early geologists, at the end of the 18th and early 19th century noticed how fossils appeared in certain sequences: some fossil assemblages were always found below other assemblages, not above.This meant that the ones below were older than the ones on top.Where are the dates coming from and how is the measurement occurring?How does the fossil record work with the geologic time scale.Sterkfontein has also yielded stone artefacts that are up to almost 2-million years old, and are the oldest dated stone tools in Southern Africa.Palaeontologist Dr Robert Broom began to recover fossils from lime mining activities at Sterkfontein in 1936.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content.

Love-hungry teenagers and archaeologists agree: dating is hard.

But while the difficulties of single life may be intractable, the challenge of determining the age of prehistoric artifacts and fossils is greatly aided by measuring certain radioactive isotopes.

Until this century, relative dating was the only technique for identifying the age of a truly ancient object.

By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
