Stratigraphy
Formation:Bavnodde Greensand
Stratigraphic resolution:group of beds
Stratigraphy comments: 'the Greensand at Jydegard is lowest Santonian and possibly highest Coniacian'
Lithology and environment
Primary lithology: lithified marl
Lithology description: 'the formation consists of poorly sorted, calcareous, glauconitic, fine-grained, silty quartz sand. Several layers of nodular greensand, quartzitic beds, and marly beds are included in the greensand, which is strongly bioturbated. In the Nyker fault block the formation consists of greensands and marls'; specimens were derived from marl
Environment:shoreface
Geology comments: classification based on high bioturbation
Taphonomy

Collection methods and comments
Collection methods:field collection
Reason for describing collection:biostratigraphic analysis
Collection method comments: Museum repositories: MGUH and GM
