Nuevas aportaciones al conocimiento estratigráfico del Paleoceno continental del Pirineo catalán (España)

Abstract

New contributions to the stratigraphical knowledge of the continental Palaeocene of the Catalonian Pyrenees (Spain)

The study of new charophyte-bearing localities allows deepening in the chronostratigraphic knowledge of the Palaeocene continental sediments of the Ager – Meià – Peguera – Valicebre basin (Catalan South-Pyrenean units). As a result the intra- or pre-Thanetian age of the continental bulimoid Vidaliella gerundensis (Vidal) Wenz, 1940 is proved. A locality in the Pyrenean basin of Tremp (Lleida province) where this gastropod occurs is described for the first time.

Several historical and bibliographic details related with the so-called “garumnian” materials (auctorum) are given aside of the stratigraphical analysis of the continental levels forming the Cretaceous / Tertiary transition.
