Two pieces filled (by inner CaCo3 crystallization) that look like: either two vertebrae or a calcite filling of karst veins. Can you give your opinion on these two forms of fossil or mineral?
Dear Smaine, these look like typical karst morphology features. O would say a broken piece of solution flute or similar. I don't see anything that would suggest fossilized remains inside.
