Sundkrogen 1a-b (Paleocene of Denmark)

Where: Denmark (55.7° N, 12.6° E: paleocoordinates 49.9° N, 9.3° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Lellinge Greensand Formation, Selandian (61.6 - 59.2 Ma)

• In Copenhagen the lower part of the Lellinge Greensand contains nannofossils of lower NP5 (Stouge et al., 2000) and planktonic foraminifera of subzone P3a or older. In the dark clay at a higher level, planktonic foraminifera indicate zone P3. Together, suggests an early Selandian age.

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, glauconitic, green, argillaceous sandstone

• The Lellinge Greensand was deposited in shallow water depths under relatively high energy conditions as indicated by the presence of cross bedding, phosphate nodules, and rolled fossils (Gry 1935, Heilmann-Clausen 1995, Claus Heilmann-Clausen pers. com. in Clause & Huuse 2002). The lithological description from Sundkrogen seems lower-energy due to the clayey nature of the units, but overall the Lellinge Greensand is the onshore equivalent to the offshore North Sea Marl, so an offshore-transition environment is assigned.
• 3.5 m green, clayey glauconitic sand, with increasing grain size upwards. The clay content is distinctly lower in the lower part.

Size class: macrofossils

Collection methods: bulk, mechanical,
