A friend found what looks like a jointed claw on the sea shore in Arichat, Cape Breton, Nova Scotia, Canada recently. She took it to the local museum in Halifax where the experts there could not id the item. It looks like bone but could be stone or wood but it could also be something carved. At a lost as to where to go to further id it, or what could be done to it to narrow down the list of possibilities. Any suggestions appreciated.
