I recently recieved the bleached skull of a Baboon I shot in Namibia in 2005. Unfortunatly the jaw has been broken. Any thoughts on an unobtrusive glue to repair broken bone?

try mixing elmers white glue with plaster into a paste and when it dries it can sanded smooth to perfection to match the skulls surface at the crack. The only drawback is that until it dries it will not hold very well. If its possible drill a few aligning holes into each side of the break and use small snips of wire as dowells then use the glue mix. www.jamesmarsico.com

There is an adhesive called Paleobond, it is for glueing bones that they did up for museums, do a googel on it.

Great ideas, thanks for your help.
