Albian-Cenomanian and Campanian-Maastrichtian biostratigraphy of southeast Spain

Abstract

The Upper Cretaceous in southeast Spain, which crops out at the southeastern end of the Iberian Range and on the easternmost border of the Betic Range, contains rich and biostratigraphically significant macrofaunas. The upper Albian is recognized by its inoceramid and ammonite content in the Internal Prebetic, the base of the Cenomanian on the basis of ammonites, and the lower Cenomanian by inoceramids, ammonites, brachiopods and echinoids. The upper Campanian has rudists in the shallow marine facies of the Iberian Domain and inoceramids in the External Prebetic, while in the Internal Prebetic it contains inoceramids, ammonites and echinoids. The lower Maastrichtian is characterized in the Internal Prebetic by inoceramids, ammonites and echinoids and in the Intermediate Units by inoceramids, brachiopods and echinoids. All taxa recorded from the Albian-Cenomanian and Campanian-Maastrichtian intervals are plotted against a reference section for each of the palaeogeographic domains distinguished.
