There is peer-reviewed research being published, as well as ongoing
research being performed, on the materials used to adhere/cohere,
consolidate and coat fossils. I'd be a lot happier to see people
going to or citing an authoritative source on this specific subject.
The issues with fossils, ivory and other related materials are
significantly different from those associated with artifacts. The
best contact in this country Is Chris Collins, who ran the Cambridge
program post-graduate diploma program  in geological conservation
and is now at the American Museum of Natural History.

In particular, please check the following publication posted in .pdf
format at the Society for the Preservation of Natural History
Collections site. It summarizes most or all of these issues from a
standpoint best calculated to answer the needs of geological and
paleontological research collections: <URL:>
