| Abstract |
Berthella arctata nov. sp. and Berthella pristina nov. sp. are described from Danian (Paléocène) of Vigny (Val d'Oise, France) and Berthella jodiae nov. sp. is described from Marinesian (Bartonian, Middle Eocene) of Le Quoniam, Haravilliers (Val d'Oise, France). No species of the genus Berthella de Blainville, 1824 is known from paleogene fauna of the Paris Basin, whereas one species is known from the Chattian (Upper Oligocene) of Aquitaine Basin. Very little, mostly questionable information is known on fossil species of the genus. The present report at Danian is the first unequivocal fossil record of Berthella, allowing the stratigraphic and biogeographic range of the genus to be extended to the Paleocene. |
