First record of Duvalia ex. gr. lata (Cephalopoda, Coleoidea) from Mexico

Resumen

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.
