like just about any organic material, dry slowly in a moderately low humidity environment until mostly dry, then store in a low humidity environment until dry and stable.
i don't know about sealing it, so if you got it too dry and moved a piece into a higher humidity area/application i would expect to see some movement anyway, but that's where i'd have to wait for somebody with more experience to chime in.
i would count it a plus that bone is generally a pretty low moisture material to begin with.
