Hehehe I see.

Well you know how I get crazy when strange and exotic materials are even hinted at..
Thought you were either talking about some rare and endangered bark from a tree only found on your island, once growing in great numbers all over Canada but now down to a dozen trees one of which just so happens to be in your backyard. This particular tree supplied the unique oil that candy canes were once flavored with but the ravenous appetites of Victorian Era children created a market second to none and the trees vanished in short order.
That tree in your backyard could save Christmas Shaun!
Either that, or I figured you meant mammoth tusk bark.
Bone is cool too though! Any chance it's the bone from the elusive and endangered pygmy mammoth squirrel also last seen on your island?
