I spent the longest day deep in the storage facilities of the archaeology department on a day when thousands of people had spent a short night waiting for sunrise at hundreds of prehistoric sites across the country. Where they were welcoming new light I was stuck inside dark rooms poking about racks and drawers of seeds and bones from the bioarchaeology reference collection. Here are totems from the present kept to compare the remains of plants and animals excavated from the past. I also spent some time talking to Dr Mike Charles and photographing some of his studies of carbonised plant remains from the Neolithic site of Catalhuyok, Turkey.
I will put some of the results online on Friday.
