We buried this ram skull a while ago and forgot about it until this week. It seems to be in fairly good condition and I'm looking for advice on preservation. The outer layer of the horn is chipping off at the base and there is an area at the back of the left upper jaw where the bone has disintegrated. I'm pretty new to this and could use some tips. I also removed a few teeth that were very loose and kept them to put back when we're done cleaning.
