La faune danienne de Vigny (Val-d’Oise, France) : importance pour l’étude de la diversification des mollusques au début du Tertiaire

Comptes Rendus de l Académie des Sciences - Series IIA - Earth and Planetary Science 06/2000; 330(12):867-873. DOI: 10.1016/S1251-8050(00)00226-3

ABSTRACT The Danian fauna of mollusca from Vigny increases from 55 to 171 species distributed in 130 genera. Extended stratigraphic ranges are given for 22 genera. The Cenozoic character of the fauna relies on the 57 exclusively Tertiary genera as opposed to only 9 genera of Maastrichtian and Danian distribution, and by a species assemblage closely similar to that of the Belgian Middle Danian.

    • "apports continentaux (faune lagunaire et abondance de galets de silex) bien représentés, indiquent le voisinage d'une communauté médiolittorale inféodée à un substrat dur (Dolin & Pacaud, 2000) adossé au Pays de Bray (qui fournissait en outre le disthène). Balayée par de fort courants, cette communauté, où régnait une vie abondante et variée avec prédominance d'espèces de petite taille, s'est déposées en accumulations de coquilles sous forme de cordons littoraux, recouverts par de nombreux nouveaux apports sableux, d'où la formation de lentilles fossilifères.

    ABSTRACT: Berthella arctata nov. sp. and Berthella pristina nov. sp. are described from Danian (Paleocene) 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.

    • "Chez les Gastéropodes, l'extinction de la fin du Crétacé est marquée à l'échelle spécifique, mais reste limitée à l'échelle des familles en Europe (PaCaud et al. 2000). Ainsi, à partir d'espèces survivantes, certaines familles vont connaître un nouvel essor. "

    ABSTRACT: A new species, belonging to the genus Hippochrenes, was recognized in the Middle Eocene (Lutetian) of the Paris basin. Hippochrenes boucheri nov. sp. has been confused up to now with Hippochrenes fissura (Coquebert de Montbret & Brongniart, 1793), the type material of which we have just rediscovered as well as the original manuscript of 1791, giving its description. This new species is discussed and compared with the Lutetian species, H. fissura and H. murchisoni (Deshayes, 1865).

    • "Th e genus Angaria has been reported sporadically in Eurasia, E. Africa and Australia within shallow warm-water faunas from Middle Jurassic to Recent, with a significant radiation since the Eocene to early Miocene (Piccoli 1984). Known Palaeogene occurrences of Angaria within the Tethys-Mediterranean region (Palaeocene–Early Oligocene) are summarized graphically in Figure 5, based on Cossmann (1915), Martin (1931), Eames (1952), Moisescu (1972), Llompart (1977), Piccoli & Savazzi (1983), Baldi (1986), Bonci et al. (2000), Pacaud et al. (2000), Harzhauser & Mandic (2001) and Harzhauser (2004). Th ese works focus mainly on Old World Cenozoic Angaria species. "

    ABSTRACT: A new trochoidean species, Angaria calvii n. sp., from the early Th anetian of the Kırkkavak Formation (Haymana-Polatlı Basin, Palaeocene) in central Anatolia, is described and placed in the family Turbinidae. Previously, the oldest Cenozoic Angaria was recorded from the Early Palaeocene (Danian) in France (Paris Basin). In this paper, we report the second discovery of the oldest angariid specimens from the Th anetian sediments of the Tethys realm, a stratigraphic position which is supported by the foraminiferal-red alga assemblages at this locality.
