serious question about prepping problem

[Newbie_1971]

So I am setting outside having some adult beverages and whittling away at this rock. Have exposed a few, but there is a good sized partial of a trilobite that it's bottom is exposed on top. How would one go about this? I would really like to have it right-side up if at all possible without damage. Is it possible to fill the bottom (exposed) and work from the other side of the rock to expose it?

Just about anything is possible if you have the right tools. The question is, is it worth the effort in the end?

I would suggest cleaning the bottom area well to remove any dust or oils, then apply a thin epoxy putty over it.  You want to make sure its got good contact over the whole of the base, so you don't end up with gaps or pockets.  Then start working down from the top side.  The good thing about epoxies is that you can color match, texture and paint them so they look like part of the natural matrix (if you want to go to that much trouble).
