Abstract

Larger foraminifera and associated fauna from the Maastrichtian of the southern valencian Prebaetic sector (E Iberian Peninsula)
The benthic foraminiferal assemblage and the associated fauna found in the Upper Cretaceous deposits of the Serra de la Solana, Valencia (Spain) have been revised. The study has allowed us to confirm the presence of the foraminiferal species Hellenocyclina beotica Reichel, Siderolites aff. calcitrapoides Lamarck, Orbitoides apiculata Schlumberger, Orbitoides gensacicus (Leymerie) and Omphalocyclus macroporus (Lamarck), as stated by previous authors. In addition, the revision has permitted to identify some other species, never cited before in Serra de la Solana and neighbour regions in Iberian Peninsula, such as Fissoelphidium operculiferum Smout and Selimina cf. spinalis Inan and two different morphotypes of rotaliids that we have left in open nomenclature, namely, Rotaliidae indet. sp. 1 and Rotaliidae indet. sp. 2. The rudists and echinoid found associated to these benthic foraminifera have been also revised. The rudist species found are Hippurites radiosus Des Moulins, Hippurites cornucopiae Defrance, Hippurites cf. lamarcki Douvillé, and Apricardia sp., the two latter cited in Serra de la Solana for the first time. The echinoid assemblage is composed of the species Pygopyrina darderi (Lambert), Linthia payeni (Coquand) and Hemipneustes striatoradiatus (Leske). The whole assemblage, typical of shallow-water platform environments, is Upper Maastrichtian in age and shows some differences in respect other contemporaneous asseblages from other paleogeographical areas.
