Abstract: Nine sections have been measured and sampled in the Coniacian and Santonian strata, well exposed along a 15 km E-W oriented continuous outcrop, at the Riu de Carreu valley and Prats de Carreu in South-central Pyrenees. They have been interpreted as representing the transition from carbonate platform to upper talus and deep shelf. The Coniacian/Santonian boundary, indicated by the first occurrence of the inoceramid Platyceramus undulatoplicatus, can be followed along the whole area, showing that its presence is relatively facies independent. The abundance of macrofauna allowed the zonation of the strata using the distribution of inoceramids and ammonites but not of echinoids. Correlation between both zonations is discused.
