Kirsty to improve upon the egg-timer

Kirsty has been funded by NERC to develop an improved egg-timer, but one which runs for slightly more than three minutes; more like three hundred thousand years....  
She and her team drawn from Archaeology and Chemistry at York, the University of Bradford, the University of Aberystwyth and Arizona State University plan to explore the reaction pathways in ostrich eggshell fragments, the ultimate “egg-timer”.   By using a combination of model systems and shell fragments they will explore how eggshell proteins decay. The then hope to put together a model of the decay pathway  and apply this model to estimate the age of eggshell fragments found in a rich archaeological sequence at Pinnacle Point, South Africa.
