[NHCOLL-L:1573] fragmenting fossils

Tue Apr 23 16:35:55 EDT 2002

Hello, 

I was wondering if anyone could give me some advise regarding the
crystallization and fragmentation of fossils. A few of our fossils are
growing white crystals which results in the specimen crumbling. There is
also an acidic smell to the specimens. Is there a way to stop this reaction?

Also, I noticed that rusty-brown dust is appearing on some of the specimens.
Possibly iron? Is there a way to stop this?

Thank you, Larkin
