Gerspee - What are the dimensions on the "hand" and what reason (s) do you have for thinking it may be from the Arctic? My reason for asking is that while my son was stationed in Alaska he sent me as a gift a small section of a fossilized mastadon tusk with the suggestion I have grips made from it for one of my guns. The color of this appears very close to your pictures. This piece was about 7" long and 2.5" wide and 1.5" thick, not large enough for a full size "hand" but maybe a miniaturized one. I didn't follow thru on his suggestion in that grips made from this material are brittle and notorious for shattering under the recoil of the gun. I'm looking for suggestions as to what to do with it.
