| Summary: | Systematic investigations of the marine beds in the Cretaceous-Tertiary sedimentary basin of West Greenland began in 1938 when the first of a long series of expeditions to this area took place. The presence of several stages not known before 1938, viz. Cenomanian?, Upper Turonian, Coniacian, Lower Santonian, Maas-trichtian and Danian, has been demonstrated by the charactej- of the marine faunas. The ages of Heer's classic fossil floras have been fixed more exactly with the exception of the Kome flora [and the interbasaltic Ivssorigsoq flora which, however, on phytopalaeon-tological evidence are probably respectively of Barrémian-Aptian and not younger than Eocene age. | The marine fauna from the beds throughout the succession is summarised, and the palaeogeographic implications are discussed. A few fossils of particular interest have been figured and pro-vided with a preliminary diagnosis, viz. a remarkable cirriped |
