You often see Jura Yellow limestone, which was fomred in the Jurassic, used as flooring in shopping centres, but I was really pleased to see that our local hospital is clad in it. The big difference for me is that in flooring, it is polished and often a bit worn, and that a lot of the detail is lost. This unpolished slab has a good few cephalopods in it, including this #ammonite; the detail visible - chambers, keel - is superb (and I love the calcite infilling).
JY comes from just near Solnofen in Germany, but it is older than the famous Solnhofen Plattenkalk. It has ammonites, belemnites, nautiloids, sponges, trace fossils (burrows etc) - a really good record of a marine ecosystem in a warm, shallow sea.
