Edad de los términos basales del Cretácico Superior de la Depresión Intermedia (Pirineos occidentales, Nafarroa)

The age of Upper Cretaceous basal sediments of the Central Depression (Western Pyrenees) has been considered to range from Cenomanian to Santonian according to previous authors. Newly studied samples show 3 planktonic foraminifera associations corresponding to M. schneegansi Zone, D. concavata Zone...
