During excavation of an 800-year-old trash dump in Lyon, France, scientists discovered the archaeological equivalent of golden shoe soles: A trove of leather soles of shoes, which is helping scientists understand how leather stays preserved in wet, oxygen-free environments. That knowledge could aid restoration of other leather artifacts, according to a report on analysis of the old soles scheduled for the current issue of ACS' semi-monthly journal Analytical Chemistry.

In the article, Michel Bardet and colleagues point out that leather consists of collagen, a tough protein that can remain intact hundreds of thousands of years under ideal conditions. The French soles were buried in mud in the absence of oxygen good conditions for preservation.
