Lithology and environment
| Primary lithology: | massive,glauconitic,shelly/skeletal,white packstone |
| Includes fossils? | Y |
| Lithology description: "massive, whitish...marine limestones" glauconite is allochthonous. "Thin sections of the layer embedding the bones (Fig. 1J) show bioclastic packstone and grainstone, with abundant and sometimes large fragments of crinoids, echinoids, ostracods, brachiopods, bivalves, gastropods, and benthic foraminifers (F. Berra, 2018, personal observation). The skeletal grains are often rounded and sometimes micritized, which indicates the presence of continuous reworking bottom currents." | |
| Environment: | open shallow subtidal |
| Geology comments: "a proximal slope or ramp, that is, an open subtidal zone reached by the effects of storm waves and with constant bottom currents, where re-sedimentation phenomena were frequent" | |

| Size of fossils: | macrofossils,mesofossils |
| Preservation of anatomical detail: | medium |
| Fragmentation: | extreme |
| Spatial resolution: | allochthonous |
