Name and quarry location: | Lumachella nera, locality unknown |
Geological description: | Fossiliferous biosparite limestone with articulate brachiopods (pentamerids?, some wholly or partially spar-infilled), solitary corals, and crinoid debris. It is of Upper Palaeozoic age. |
Comments: | This black limestone, with its delicate thin-shelled brachiopods, was probably not used in ancient times, and the location of the quarry is not known. Raniero Gnoli suggested it was first used in the 17th century, and it was employed sparingly in furniture and stone collections sold to the 'grand tourists visiting Rome in the 18th and 19th centuries. |
