Campanian and Maastrichtian ammonites from East and North-East Greenland

Newly collected ammonites from Campanian and Maastrichtian strata in East and North-East Greenland are described. An early early Campanian fauna from Hold with Hope includes Neophylloceras, Pseudophyllites, Gaudryceras (Gaudryceras) mite (Hauer 1866) and Baculites. A latest early Campanian fauna from Geographical Society Ø comprises Pseudophyllites latus (Marshall 1926), Hoploscaphites cobbani (Birkelund 1965), and Baculites sp. Late Campanian assemblages from Geographical Society Ø and Traill Ø include Hoploscaphites greenlandicus (Donovan 1953) and Hoploscaphites compressus (Roemer 1841). In the Kangerlussuaq Basin, East Greenland, an early early Maastrichtian fauna contains Acanthoscaphites (Acanthoscaphites) tridens (Kner 1848), together with Anagaudryceras politissimum (Kossmat 1895) and other taxa. A later fauna is characterised by Discoscaphites angmartussutensis Birkelund (1965). Generally, early Maastrichtian faunas of the Kangerlussuaq Basin are dominated by Diplomoceras cylindraceum (Defrance 1816), and also contain Anagaudryceras, Saghalinites, and Baculites, together with the nautiloid Eutrephoceras. Maastrichtian faunas also occur reworked into the Paleocene. Most of these taxa are reported for the first time from eastern Greenland in this study, and their occurrence supports the existing stratigraphy.
