PhD Research project
Dating hominin exploitation of Paleo- and Mesolithic coastal sites using amino acid racemisation
The project attempts to develop a method of dating shells from marine and coastal sites in an effort to improve a dating of sites which are important to the early habitation of hominins. Shells are biominerals, in which an organic (mainly proteic) matrix is deeply embedded in a calcium carbonate skeleton. The idea behind this project is to isolate a closed system in which proteins will decay under predictable conditions. Because the rate of decay is improved strongly by temperature it is hoped that these data can show climate changes occurred in the past. The plan is to analyze a number of coastal sites from around the world including the earliest modern humans in Britain, the last Neanderthal in Gibraltar and the earliest humans in South-East Asia.
Coastal Archaeology & Chronology
