Where: Greenland (70.2° N, 22.1° W: paleocoordinates 67.8° N, 13.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Kap Dalton Group, Early/Lower Oligocene (33.9 - 28.4 Ma)

• STRATIGRAPHIC RELATIONS: From the "Coeloma beds" of the Kap Dalton series, which overlies the Kap Dalton series (Paleogene) AGE: Paleogene, on the basis of crude biostratigraphy; reassigned on the basis of known age ranges from more recent literature; assigned by enterer to Early Oligocene on the basis of age range for Aporrhais speciosa. STRATIGRAPHIC POSITION: From the 36 m thick Coeloma bed.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified, gray sandstone

• ENVIRONMENT: Shallow marine siliciclastic.
• SPECIFIC LITHOLOGY: Grey sandstones and marls, with thin bands of hard sandstone. LITHIFICATION: Lithified on the basis of figured specimens.

Size class: macrofossils

Collection methods: surface (in situ),

• COLLECTORS: Multiple collectors from the 1951 Danish Expedition to East Greenland, including L. Koch, D. Mackney, and F. Sherrell (University of Bristol). REPOSITORY: MMC?
