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.
