Lithology and environment
| Primary lithology: | "siliciclastic" |
| Lithology description: In general description of this community: "Shells occur in a largely disarticulated condition, either as coquinas or scatttered valves, in fine-grained sandstone to mudstone-siltstone..." | |
| Environment: | transition zone/lower shoreface |
| Geology comments: "Geographic and stratigraphic relations with associated communities are consistent with BA 2. The environement was commonly turbulent enough to disarticulate the valves..."
