“…The upper part of the Atane Formation, the Qilakitsoq Member, is known from outcrops at Tunoqqu and Kangersooq up to 700 m a.s.l and from boreholes in the Agatdalen valley (Dam et al 2000). In the Agatdalen area the Atane Formation is dominated by marine delta front and shoreface deposits of late Santonian age (Dam et al 2000). The Qilakitsoq Member is unconformably overlain by deep-water marine sediments of the Aaffarsuaq Member of the Itilli Formation (Dam et al 2000(Dam et al , 2009.…”

“…In the Agatdalen area the Kangilia Formation is known from small outcrops, which include the erosive boundary to the overlying Agatdal Formation (Figs 2 and 4). The Oyster-Ammonite Conglomerate Bed in Agatdalen comprises reworked Danian fossils (1974) and Dam et al (2000Dam et al ( , 2009. Outcrops are mostly found in river sections.…”

“…The detailed logs from localities 1, 2, and 4 are from Dam et al (2009). The simplified logs from localities 3 and 5-7 are based on the descriptions in Koch (1963) and Dam et al (2000Dam et al ( , 2009 (Dam et al 2009). It is therefore younger than the Maastrichtian Annertuneq Conglomerate Member (Nøhr-Hansen & Dam 1997, Dam et al 2009) and has been included in the Kangilia Formation.…”

ABSTRACT. The Cretaceous and Palaeogene floras of western Greenland that were initially described as part of the classical work "Flora fossilis arctica" by Oswald Heer in the 19 th century are currently under revision. The Nuussuaq Basin has repeatedly been investigated by geologists and marine invertebrate palaeontologists. These studies provide a modern stratigraphic framework and a basis for revisions of various Cretaceous to Eocene floras from this region, and the correlation of fossil material to stratigraphic units and formal formations. This paper is the first in a series of papers that (i) correlate macrofossil (museum) material and fossil-rich localities with the modern lithostratigraphic framework, (ii) describe new pollen, spores, and other marine/freshwater palynomorphs, and (iii) revise the macrofossil remains from the Agatdalen area (particularly the Danian Agatdal Formation). Since the work of B. Eske Koch in the 1960s and 70s, questions emerged about the correlation of plant fossiliferous outcrops and whether the so-called Agatdalen flora, referred to the Agatdal Formation, originates from a single sedimentary unit or not. In this paper, we summarise the stratigraphy of the Agatdalen area and correlate the fossil plant-bearing outcrops described by Koch to the current lithostratigraphy. We establish which plant fossils belong to the Agatdal Formation and re-assign a great number of other plant fossils to their correct formations. New palynological material is briefly described and correlated to the macrofossil localities and the Agatdal Formation. Previous accounts on the macrofossils (leaves, fruits, seeds) are briefly discussed and directions for future revisions are outlined.
