Bavnodde Greensand Formation, Jydegard, Bornholm (Cretaceous to of Denmark)

Where: Denmark (55.1° N, 14.8° E: paleocoordinates 45.1° N, 14.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Bavnodde Greensand Formation, Late/Upper Coniacian to Late/Upper Coniacian (89.3 - 83.5 Ma)

• 'the Greensand at Jydegard is lowest Santonian and possibly highest Coniacian'

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; lithified marl

• classification based on high bioturbation
• '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

Size class: macrofossils

Preservation: mold/impression
