Correlation diagram of Cenomanian to Santonian sections from the Iberian shallow margin to the basin, on a north-south transect from Àger to El Pont de Suert. This diagram incorporates three outcrop sections examined in this study and three sections from Drzewiecki and Simó (2002) (La Serra, Llastari and Sopeira; locations in Fig. 1). Correlations are based on biostratigraphy (benthic and planktonic foraminifera) and 11 recognized stratigraphic cycles (LC0 to LC10) delimited by maximum regressive surfaces (Ce0 to Sa2).
