mbarco Posted July 4, 2022 Share Posted July 4, 2022 Decalcified specimen from the Upper Ordovician of Italy. Scale bar: 5mm. It's possible to define at least the Order of this Mollusca, or it's pretentious to think so? It might belong to Gastropoda, Nautiloidea (i.e. Tarphycerida...),...? The attached image is formed by three pictures, the two on the left show the external mould, while the one on the right shows the internal mould.
