Les scléractiniaires du Barrémien-Aptien inférieur de Provence (SE de la France)

In the Urgonian limestones from Provence of Barremian-Early Aptian age, 29 scleractinian speciesare described, belonging to 14 families and five suborders: Amphiastreina, Rhipidogyrina, Archaeocoeniina, Stylinina et Astreoina. The suborder Stylinina Alloiteau, 1952, is emended. Twenty genera are recognized among with two new: Saltocyathus and Rhipidomeandra (Rhipidogyrina). Among the 29 species identified, six are new: Donacosmilia massaliensis, Paraclausastrea valclusensis, P. pulchra, Diploastraea crassicostata. Two species belong to the new genera (Saltocyathus urgonensis, Rhipidomeandra bugrovae). On a european scale this fauna tends to characterize the Barremian-Early Aptian interval and shows a strong affinity with the Carpathian fauna even if some of the species are also found in other regions.

Les Scléractiniaires hydnophoroïdes du Crétacé inférieur (Barrémien-Aptien inférieur) de Provence (S.E. de la France). Systématique, stratigraphie et paléobiogéographie

From the Barremian-Early Aptian platform carbonates (Urgonian facies s.l.) from Provence, seven species of hydnophoroid Scleractinia are described. They belong to genera Eohydnophora and Felixigyra (Faviidae) and Hydnophoromeandraraea (Microsolenidae). Two species are new. These taxa are original features of the Provence fauna. Hydnophoromeandraraea shows a restricted palaeobiogeographic distribution, the Felixigyra-Eohydnophora group has a wider one (Eurasia-East Africa and America).
