Is trying to split this crappy brittle star fossil worth it?
idiot posted a topic in Fossil PreparationI found this worn piece of Berea Sandstone that seems to have once hosted a bunch of brittle stars on the face. How would you calculate the risk:reward ratio wrt splitting it to see if there are pristine brittle star fossils inside, and if so, what's the best method to expose potential fossils without an air scribe and without jeopardizing the brittle stars that are exposed? It's about an inch thick and has a very, very, very slight hint of a fissure near the face. Sorry for the poor pics.
