Here we present the first record of the belemnite Duvalia ex. gr. lata (Cephalopoda, Coleoidea) from Mexico. The unique individual, a well-preserved rostrum, was discovered in Early Cretaceous strata of the Sierra de Parras close to Viesca in southwestern Coahuila. Duvalia ex. gr. lata was previously known from the Mediterranean Tethys. Our report extends the paleogeographic distribution of Duvalia to the western hemisphere and supports the hypothesis that the Hispanic Corridor was open during the Early Cretaceous, allowing for marine faunal exchange and migration between the Gulf of Mexico and the European Tethys.
