Particularidades de los macroforaminiferos del Cenomaniense de la Cordillera Ibérica: implicaciones paleobiogeográficas

The distribution of Larger Foraminifera in the Iberian Range during the Cenomanian is being studied. The occurrence of Ovalveolina maccagnoae, Sellialveolina viallii and Pseudedomia drorimensis on the shelves of the lower depositional cycle (Upper Albian-Middle Cenomanian) implies a Tethysian origin...

Sumario:The distribution of Larger Foraminifera in the Iberian Range during the Cenomanian is being studied. The occurrence of Ovalveolina maccagnoae, Sellialveolina viallii and Pseudedomia drorimensis on the shelves of the lower depositional cycle (Upper Albian-Middle Cenomanian) implies a Tethysian origin of the sediments. In contrast, during the upper depositional cycle (Upper Cenomanian) the Larger Foraminifera assemblages are related to the Pyrenean Culf with the exception of Cisalveolina. Us occurrence in the north-eastern part of the Iberian Range, however, indicates a communication with the Tethys realm. The Cenomanian age attributed to the uppermost shallow platform facies implies that carbonate sedimentation stopped before the deposition of Middle Turonian hemipelagic sediments
