Hi!  I recently found some large nacreous bivalves, which are embedded in concretion-like cobbles.  The matrix is very easy to remove, but the nacre starts flaking as soon as it is exposed to air.  Is there a product to stabilize these without future discoloration?  Thanks! (Also if anyone can identify, that would be cool--they come from near Scenic, SD)

I agree - it is some specie of Inoceramid. 

You could coat them with paraloid. 

Do a search of the Forum for paraloid - many topics and answers already posted in the Fossil Preparation sub-forum.  :)

As stated above, Paraloid B-72. Use a 1:20 solution or thinner and apply an even coat with a foam brush.
