Lithology and environment
| Primary lithology: | bioturbation,concretionary,gray cherty/siliceous lime mudstone |
| Lithology description: Grey-weathering nodular limestone beds have characteristic undulating and knobby surfaces spaced from cm to dm apart, and consist mainly of filament- and radiolarian-microsparites (mudstone-wackestone), often strongly bioturbated. Silicification may be diffuse or nodular. Often mixed with fine ash- and crystal-tuffs. | |

| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | surface (in situ),field collection |
