Restos mandibulares de un cocodrilo marino (Thalattosuchia, Metriorhynchidae) del Llano Yosobé, en Tlaxiaco, Oaxaca, México

La familia Metriorhynchidae (Crocodylomorpha) agrupa a cocodrilos marinos altamente especializados, habitantes permanentes de mar abierto y depredadores exitosos en los mares tropicales del Jurásico. Los metriorrínquidos cuentan con un amplio registro fósil en Europa y América del Sur mientras que en América del Norte sus restos son muy escasos con un par de especies descritas en el Norte y centro de México. Otros ejemplares de metriorrínquidos de afinidad incierta se han encontrado en Cuba. En este trabajo se presenta un nuevo ejemplar de metriorrínquido del Jurásico de la Formación Sabinal (Kimmeridgiano), identificado como un Metriorhynchinae indeterminado con base en algunos rasgos dentales. Este ejemplar se suma a la diversidad y alta riqueza de ejemplares que ofrece la localidad del Jurásico Superior conocida como Llano Yosobé al sur de México.
