Side A out of the vinegar. I began the mechanical prep and…. OMG!!! I’m doing a bit from Illinois!! Small but mighty! It’s covered, actually a conglomerate rock of gastropods (curly-Q and spiral shells) many are open exposing the lovely chambers filled with calcite (clear spiky sparkly) crystals! It’s going to be STUNNING. plus, it has not just crinoid beads on it — it has THE most sought after, rarest crinoid on it — STARS!! Tiny stars scattered here and there.
