%X Bulk sampling of upper Campanian to lower–middle Maastrichtian coastal and lagoonal deposits in fivesections of the Tremp Formation in the south-central Pyreneesyielded numerous neoselachian teeth. The fauna comprisesnine taxa of which three species and one genus are new:Hemiscyllium sp., Lamniformes indet., Paratrygonorrhinaamblysoda gen. et sp. nov., Coupatezia trempina sp. nov.,Coupatezia sp., Coupatezia? sp., Rhombodus ibericus sp. nov.and Igdabatis indicus. The neoselachian fauna is dominatedby small nectobenthic rays. This composition resemblesassemblages known from the marine Upper Cretaceous, butdiffers from nearby localities of the Basque-Cantabrian regionand continental selachian associations of the French Pyrenees.The results indicate that Rhombodus might not be a reliablebiostratigraphic marker for the Maastrichtian. The faunalcomposition suggests a shallow trans-Tethyan connectionbetween Eurasia and India at the end of the Cretaceous Period.
