Alianaitsúnguaq, Nugssuaq (Cretaceous of Greenland)

Where: Greenland (70.4° N, 53.7° W: paleocoordinates 58.2° N, 16.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Scaphites ventricosus ammonoid zone, Middle Coniacian (89.3 - 85.8 Ma)

• all specimens are collected from horizon 20

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, concretionary, calcareous shale

• 'horizon 20 which consists of dark, bituminous shales with subordinate, light coloured sandy intercalations and yellowish concretionary layers. Calcareous concretions at this level contain ammonites, other marine fossils and plant remains.'

Size class: macrofossils

Preservation: mold/impression

Collection methods: 'Most of the material described in this paper was collected during the Nugssuaq Expeditions in 1938-1939 and during the current geological mapping of Svartenhuk and Nugssuaq under the auspices of the Geological Survey of Greenland. Both were carried out under the leadership of Professor A. Rosenkrantz.' The author himself joined two of the expeditions.
