RT Journal Article T1 Lower Bathonian ammonites of Serra de la Creu(Tivissa, Catalan Basin, Spain) A1 Fernández López, Sixto Rafael AB The study of ammonites of the Bajocian/Bathonian boundary from Serra de la Creu (Tivissa, province of Tarragona), a locality of theCatalan Basin, allows to recognize several bio- and chronostratigraphic units commonly missing in the Iberian Basin. The ParkinsoniZone (Upper Bajocian) and the lowermost Zigzag Zone (Lower Bathonian) established for NW Europe areas can be identified in theCatalan and Iberian basins (Spain), although the ammonite fossil assemblages are composed by Submediterranean taxa.
