Stratigraphy
| Formation: | Arnager Greensand | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: 'Inocermid fauna of the basal part of the greensand... the Arnager Greensand s. str. can be referred to the lower Middle Cenomanian on ammonite and inoceramid bivalve evidences... on foraminiferal evidence, the basal 5 m of the greensand is from the Lower Cenomanian' | |||||
Lithology and environment
| Primary lithology: | bioturbation,glauconitic poorly lithified sandstone |
| Lithology description: 'poorly sorted, glauconitic quartz sand... the greensand is unconsolidated except for a few cemented beds in the basal part and is heavily bioturbated.' | |
| Environment: | shoreface |
| Geology comments: classification based on high bioturbation | |

| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | field collection,survey of museum collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Museum repositories: MGUH, GM, MMH and MM | |
| Taxonomic list comments:fragments are not included in abundace data of belemnites | |
