New Echinoid (Spatangoida: Toxasterinidae) from the Campanian of Coahuila, Northeastern Mexico
ABSTRACT Three specimens corresponding to a new echinoid species from the Upper Cretaceous (Lower Campanian) from Austin Formation in the northeastern of Mexico are reported here. The morphology of the specimens (test with a cordiform aboral region) as well as the sedimentary environment reported a...

| description | ABSTRACT
Three specimens corresponding to a new echinoid species from the Upper Cretaceous (Lower Campanian) from Austin Formation in the northeastern of Mexico are reported here. The morphology of the specimens (test with a cordiform aboral region) as well as the sedimentary environment reported at the Austin Formation, suggests that this species represents an infaunal and detritivorous dweller living in a shallow water environment within the continental shelf. This is consistent with the more actual knowledge for other species of Diplodetus Keywords: Echinoids, Diplodetus, Upper Cretaceous, Campanian, Austin Formation, NE Mexico.
RESUMEN
Se reportan tres especímenes de Diplodetus brisenoi, una nueva especie de equinoideo del Campaniano Inferior (Cretácico Superior) de la Formación Austin, en Jiménez, Coahuila, noreste de México. Tanto su morfología (testa con ámbito cordiforme) como el ambiente de depósito reportado para la Formación Austin sugieren que esta especie representa un elemento de la infauna con hábitos detritívoros en ambientes de plataforma, lo cual es consistente con lo reportado para otras especiesdel género Diplodetus.
