Re: breaking up hard rocks
Is this Triplehorn fellow interested in Triceratops by any chance?

Basically, Triplehorn says that warm DMSO (dimethyl sulfoxide) works
extremely well on many types of sandstones as well as limestones -
even as quickly as overnight. The fossils he worked with (teeth and
bones) were phosphatic, but carbonate shells came through the
disaggregation process well. He states that the product is available
at feed and pet stores or on the internet. The only negative he
mentions is that it is easily absorbed through the skin and large
quantities may be fatal, so use caution if you decide to try it.
