Lithology and environment
| Primary lithology: | black unlithified claystone |
| Environment: | offshore |
| Geology comments: Most of the gastropods studied in this monograph come from clayey facies of more or less open sea environments (Wawal: The faunal assemblage suggest shallow water conditions near the photic zone in the lower and upper parts of the section and a deeper water conditions in the middle part). | |

| Size of fossils: | mesofossils,microfossils |
| Preservation of anatomical detail: | excellent |
