My girlfriend is wine tasting her way through Italy for a few weeks. Tough gig huh? Anyways, today she’s in Tuscany and the winery she was at had a display and story of how the soil was very fossiliferous. No listing of geological age and the server there didn’t know much more either. She wasn’t sure which area of Tuscany she was in and the geologic maps I looked up seemed to run anywhere from upper cretaceous on. She managed to talk them out of one of their display pieces for me, with a fairly good sized wine order no doubt! She only sent this one photo, and they packed it with her wine to ship, so I don’t have a lot to go by until I have it in hand. It’s an interesting rock and kind of has the look of some Schist like formations I’ve seen her in the states. I can kind of imagine possible shell imprints in a few places but not sure. Or could the whole piece be fossil? Not sure. Any guesses or illumination would be appreciated. Thanks!
