The sites and the finds

It’s not just the finds that are unique. Every archaeological site has its own characteristics and challenges.

There are a vast number of archaeological sites throughout the world that we could have selected for this course. They are each intriguing in their own way and provide a different experience to the researchers who work at them.

We have selected three very different sites for you to consider – with vastly different landscapes, geological contexts and histories. We’ll visit a limestone outcrop in Morocco, a cave gouged out by a river in Indonesia, and a huge, shifting sand dune in Australia.

We’re looking at a range of ages as well, starting from the archaeologically older finds and ending at the younger. We’ll see that when it comes to dating human evolution – younger doesn’t necessarily mean easier.

  • We’ll consider work that was done in the 1960s, right up to studies that are currently being conducted.

  • We’ll consider finds that were made accidentally and finds that were made whilst looking for something else.

  • We’ll see fossils that were carefully documented and have detailed recordings of their locations when found – and fossils for which we have little or no idea of where they came from on the site.

  • We’ll see evidence consisting of skulls, bone fragments, and nearly-complete skeletons. But we’ll also mention stone tools, animal bones and fire hearths.

Our aim here is to show you that archaeological research is carried out in a very broad context indeed. The principles and science that we have considered are applied to a huge range of evidence and environments – each bringing with it their own set of considerations. The amount of work that is carried out today from the very first site surveys right up to the published research paper (and subsequent debates) is not only meticulous in detail, but enormous in volume.

And the work doesn’t end there. New advances in technology and new discoveries in the field then send us back to re-examine old evidence and sites to see what new knowledge we can gain. New tests are conducted, new results and theories are published, and new debates are begun.

It’s a remarkable journey.
