| dc.description.abstract | The Tithonian rock succession (Vaca Muerta Fm.) of Portada Covunco consists of a lower part of little more than 100 m of shales and shaly limestones with ammonites of the genera “Lithacoceras”, Choicensisphinctes and Pseudolissoceras of the Mendozanus and Zitteli zones; the middle part consists of about 160 m of limestones and marly limestones with ammonites of the genera Aspidoceras and Catutosphinctes of the Proximus? and Internispinosum zones; ending with some 45 m of unfossiliferous mudstones and shaly marls. Catutosphinctes Leanza & Zeiss (Ataxioceratidae: Torquatisphinctinae), a genus widely distributed through all the Tithonian of the southern Neuquén-Mendoza Basin, occurs through the more calcareous upper part of the section, mainly the type species Catutosphinctes rafaeli Leanza & Zeiss. | en_US |

Vaca Muerta) de Portada Covunco consiste de una parte inferior de poco mas que 100 m de pizarras y calizas o margas pizarrosas con amonites de los géneros “Lithacoceras”, Choicensisphinctes y Pseudolissoceras de las zonas Mendozanus y Zitteli; una parte media de unos 160 m de calizas y calizas margosas con amonites de los géneros Aspidoceras y Catutosphinctes de las zonas Proximus? e Internispinosum; culminando con unos 45 m de limolitas y margas pizarrosas sin fósiles. Catutosphinctes Leanza & Zeiss (Ataxioceratidae: Torquatisphinctinae), un género ampliamente distribuído en todo el Tithoniano de la cuenca, se presenta en todo el tramo calcáreo superior de la sección, principalmente su especie tipo Catutosphinctes rafaeli Leanza & Zeiss. | en_US |
