| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The Langmoos Member is only present in basal part in the left (northeastern) part of the quarry, where it is 1.5 m thick | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal,green,red or brown lithified calcareous "limestone" |
| Includes fossils? | Y |
| Lithology description: red, grey and greenish limestone bioclastic limestones with brachiopods, crinoids, sponge spicules | |
| Environment: | deep subtidal ramp |
| Glacial or sequence phase: | transgressive systems tract |
| Geology comments: At the boundary of Calliphyllum (Planorbis) and Liasicus Zone, late LST and transgresive system tract conditions are supposed. Onlap of the Schnoll Formation at the slope as a lowstand edge. Poorly oxygenated, nutrient-rich bottom waters fostered dense sponge populations. | |

Collection methods and comments
| Collection excludes: | all microfossils,some macrofossils,difficult macrofossils |
| Collection methods: | bulk,mechanical,field collection |
| Reason for describing collection: | taxonomic analysis |
