AB The palaeogeography and facies distribution of the Catalan Basin during the Middle Jurassic are reconstructed, on the basis of outcropsand logs data. A new lithostratigraphic classification valid for the Catalan Basin is defined and its equivalence with the correlativeunits in the lberian Basin and Majorca is discussed. A system of arched, listric-shaped faults dipping towards the Mediterraneansea was a major factor determining the differentiation of the subsident Platform of Tortosa. From a palaeobiogeographical pointof view, the ammonite and brachiopod recorded associations from the Platform of Tortosa are taxonornically similar to the associationsof the epicontinental European basins. The Catalan Basin and Majorca were two geographically separate areas, maintainingseparate biogeographical and taphonomic dispersal ways in the Middle Jurassic. Yet in the Catalan Basin expanded, outer shelf sectionswere developed during the Garantiana Biochron (Upper Bajocian). During this episode the basin reached the maximum bathymetricvalues and acted as a biogeographical dispersal area for some taxonomic groups characteristic of the West-Tethys.
