Hi, Among the many delights I've encountered since starting at Bolton was a partial plesiosaur skeleton, cast into a hard yellow-orange resin. It's been used as a handling object by our education department for many years now. Well, I've now found the rest of the skeleton and come to two conclusions. 1.It's an Icthyosaur. The resin cast "head" was among the pieces I found. It's basically the tip of an Icthyosaurs jaws. The rest of the skull is missing. This didn't stop the intrepid caster however, who attached the jaws to the last of the vertebrae and then sculpted the outline of a head around the whole mess! 2.I'd really like to get it out of the resin, giving me the opportunity of displaying what would probably be a pretty decent specimen. So, the actual point of all this. Has anybody any idea how to safely remove the fossil from the resin? anybody encountered this before? I'm guessing some form of heat treatment is my best option, but any advice/offers/suggestions are most welcome.
