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.
Cheers,
David
