Radicarbon dating samples

Was able to escape the thrills of writing about pigs diets and isotopes, as I was just dragged off to advise on, and select samples for radiocarbon dating from the Banjo enclosure at North Down, Dorset. This is a large Bournemouth University dig, which had a team of up to 160 excavators and specialists. The 2011 season finished only a couple of weeks ago and post-ex is now in full swing. As for the samples, there wasn’t a lot to choose from. It’s crucial to pick a bone (or whatever else) that you can be confident has not been kicking about for long periods prior to ending up in the deposit you want to date. You don’t want to waste your money dating something that was dug out of a much earlier pit before finding its way into your deposit. One bone, a cattle radius, was about three quarters complete and although it had evidence of weathering showing it could have been on the surface for some time I’m confident it will provide a good date for the ditch from which it came.
