In the early 1990's David Grattan's laboratory at the Canadian Conservation Institute in Ottawa, Ontario experimented with the stabilization of botanical materials from arctic Axel Heiberg Island, a 45 million year old frozen desert. He did some work with sublimating parylene C onto the material to hold the leaf litter mats in place.
