I would like information on the geology of the Republic of S. Marino, a geological map of the same Republic; and news on any papers on the ichnology of invertebrates of that Republic. In a recent visit to S. Marino on 24.01.2023 I saw Burrows and large trails of invertebrates on the stone slabs of the road pavement of that capital of the Serenissima Republic of S. Marino. Any paper or map on this topic?
