These techniques both place assemblages of artefacts into relative order.Petrie used sequence dating to work back from the earliest historical phases of Egypt into pre-dynastic Neolithic times, using groups of contemporary artefacts deposited together at a single time in graves.Dr Green says in the past archaeologists had unrealistic expectations of how easily and precisely the scientists can date things, and are surprised when things don't go to plan.But she says that since she has been working side-by-side with them the mutual understanding has grown.
"There are important opportunities for archaeological science in Australia at the moment, where the field is not as highly developed as it is in some other parts of the world, particularly in Europe," says Professor Gleadow.
"If you haven't done the hard yards to really understand what that material is, and how it got there, how stable it is and all these other aspects, you are wasting your time.
Mr Finch has found that the charcoal used to date mud wasp nests is often already old before being added to the nest (up to 1000 years old), so any dates from these nests need to be adjusted using advanced statistical techniques to take this into account.
The transformation of archaeological dating that began around 1950 continues, but archaeologists may overlook the revolution in scientific dating that had already taken place in geology during the first half of the twentieth century; from this wider perspective, the emergence of radiocarbon dating may seem slightly less dramatic Accurate knowledge of the age of the Earth was of little direct help to archaeologists, but it emphasised the potential of scientific dating techniques.
The first half of the twentieth century witnessed similar progress that began with the dating of recent geological periods in which early hominids lived, and ended with the introduction of radiocarbon dating.
