Abstract

The Late Cretaceous in the westernmost sector of the External Sierras (Sto. Domingo range) is poorly represented but displays transitional facies where remains of continental and marine fossil vertebrates (Osteichthyes, Chondrichthyes and Dinosauria) were recently discovered. This paper introduces the preliminary magnetostratigraphic results carried out in 4 small sections. The characteristic magnetization of these rocks is stable, primary and shows two polarities of the magnetic field. A tentative correlation considering our local sequence of polarities and the chronostratigraphy of vertebrates from the Graus-Tremp basin relates the fossil locality with the chron C32n (Campanian) and the Garum facies with C29r, C29n and C28r (Maastrichtian and Danian). This correlation implies a hiatus during the Maastrichtian that should be confirmed in future sedimentological studies.
