Lithology and environment
| Primary lithology: | lithified grainstone |
| Secondary lithology: | flat-pebble lithified conglomerate |
| Includes fossils? | Y |
| Lithology description: Calcisiltite, medium gray, thin bedded, intraformational conglomerate in thin beds, very fossiliferous. | |
| Environment: | deep subtidal ramp |
| Geology comments: Multiple sources indicate that this was a carbonate dominated ramp, with substauntial siliciclastic input, below normal wave base, above storm wave base. | |

| Modes of preservation: | replaced with silica |
Collection methods and comments
| Collection excludes: | some macrofossils,some microfossils |
| Collection methods: | field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Taxonomic list comments:The faunal lists in Hintze 1952 are updated versions of those in Hintze 1951 and, so, are used here. | |
