Faunal evidence of a holocene pluvial phase in southern Arabia with remarks on the morphological variability of Helenina anderseni

Gennari, Giordana ; Rosenberg, Thomas ; Spezzaferri, Silvia ; Berger, Jean-Pierre ; Fleitmann, Dominik ; Preusser, Frank ; Al-Shanti, Mahmoud ; Matter, Albert

In: The Journal of Foraminiferal Research, 2011, vol. 41, no. 3, p. 248-259

Although foraminifera have been found living in inland saline lakes isolated from the sea, this phenomenon has rarely been recognized in the fossil record. This study documents the occurrence of benthic foraminifera in Holocene lake sediments located nearly 500 km inland from the Red Sea, in the Al-Mundafan region of southern Saudi Arabia. The lake formed during a regional pluvial period,...

Iberomeryx minor (Mammalia, Artiodactyla) from the Early Oligocene of Soulce (Canton Jura, NW Switzerland): systematics and palaeodiet

Mennecart, Bastien ; Becker, Damien ; Berger, Jean-Pierre

In: Swiss Journal of Geosciences, 2011, vol. 104, no. Suppl. 1, p. 115-132

The primitive ruminant genus Iberomeryx is poorly documented, as it is essentially only known from rare occurrences of dental remains. Therefore, the phylogeny and palaeobiology of Iberomeryx remain rather enigmatic. Only two species have been described: the type species I. parvus from the Benara locality in Georgia, and the Western European species I. minor reported from France, Spain, and...

Large mammals from Rickenbach (Switzerland, reference locality MP29, Late Oligocene): biostratigraphic and palaeoenvironmental implications

Mennecart, Bastien ; Scherler, Laureline ; Hiard, Florent ; Becker, Damien ; Berger, Jean-Pierre

In: Swiss Journal of Palaeontology, 2012, vol. 131, no. 1, p. 161-181

Since the first exploitation of the Huppersandstones quarry of Rickenbach (Canton Solothurn, Switzerland) in 1898, many fossils of plants, molluscs, and vertebrates have been discovered. The study of the small mammals brought this locality to international recognition as the type locality for the European mammalian reference level MP29 (latest Oligocene). Our study reviews the terrestrial...

Sédimentologie et paléontologie des paléoenvironnements côtiers rupéliens de la Molasse marine rhénane dans le Jura suisse

Picot, Laurent ; Becker, Damien ; Cavin, Lionel ; Pirkenseer, Claudius ; Lapaire, Frédéric ; Rauber, Gaëtan ; Hochuli, Peter A. ; Spezzaferri, Silvia ; Berger, Jean-Pierre

In: Swiss Journal of Geosciences, 2008, vol. 101, no. 2, p. 483-513

Les dépôts oligocènes marins, situés dans la partie distale du bassin molassique suisse et dans le prolongement sud du fossé rhénan, sont constitués par les groupes stratigraphiques suivants: les Conglomérats de Porrentruy, le Septarienton et le Meeressand. Cette série sédimentaire a fait l’objet d’études stratigraphiques, sédimentologiques et paléontologiques détaillées. Trois...
