Stratigraphy
| Formation: | Arnager Greensand | ||||
| Stratigraphic resolution: | bed | ||||
| 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'; the inocermids where derived from an 'indurated bed in the basal part of the Arnagar Greensand' | |||||
Lithology and environment
| Primary lithology: | bioturbation,glauconitic 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 | |

| Collection methods: | field collection |
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Museum repositories: MGUH and GM | |
| Taxonomic list comments:Focus on inoceramids. | |
