Removing of cypsum-crystals from fossil bone

["Mikko K. Haaramo" <mikko.haaramo@helsinki.fi>]

Hi,

What is the safest method of removing outgrowth of cypsym-crystals from a
bone-surface?

I'm trying to slightly prepare the specimen of which I put a identification
question to vrtpaleo last week.
[http://www.helsinki.fi/geology/mystery_fish.html]

The answers so far indicate that the speciemen and the label are mixed, so
disrecard the label.
Also the outer structure and preservation seems to indicate that this is a
frontal-parietale with crushed braincase.

The most resonable suggestion so far has been that this is a large, prob.
North African, catfish.
Which corresponds nicely since we have some other catfish material in our
collection (finspine with associated cleithrum).


Cheers!
