72 specimens of ammonites and the nautilidEutrephoceras, collected from the upper Cretaceous Parras Shale at Saucedas in southern Coahuila, Mexico, are here assigned to twelve genera and fourteen species. The assemblage represents three to four upper Campanian biozones reaching from the Western Interior lower upper CampanianExiteloceras jenneyito the uppermost Campanian TethyanNostoceras hyattibiozone.Eutrephoceras irritilasiandTrachyscaphitessp. are endemic taxa, whileBaculites taylorensisis restricted to the northern Gulf of Mexico Coast andE. jenneyi,Oxybeloceras crassumandSolenoceras elegansare Western Interior Seaway elements.Didymoceras donezianumis a southern Euramerican species, whileBostrychoceras polyplocumandN. hyattioccur throughout lower and middle latitudes.Diplomoceras cylindraceumandPhyllopachyceras forbesianumare cosmopolitan taxa with their main occurrences in the Maastrichtian; their record at Saucedas is the oldest of these species in North America. A clear paleobiogeographic signal is identified in the upper Campanian ammonite assemblages at Saucedas by a change from restricted towards geographically widespread faunas. This suggests gradual disappearence of faunal barriers which separated the Gulf Coast from the rest of the world.
