First occurrence of Cloudina carinata Cortijo et al., 2010 in South America, Tamengo Formation, Corumbá Group, upper Ediacaran of Midwestern

espanolSe documenta en este resumen la primera aparicion de Cloudina carinata Cortijo et al., 2010 en el continente americano. Esta nueva aparicion extiende la distribucion geografica de esta especie, hasta ahora restringida a Espana y Siberia. Se presenta por primera vez en la Formacion de Tamengo (Corumba, Estado de Mato Grosso do Sul, Brasil) la asociacion de metazoos mineralizados compuesta por Cloudina carinata, Cloudina lucianoi (Beurlen & Sommer, 1957) y Corumbella werneri Hahn et al., 1982. Esta asociacion podria ser util como marcador bioestratigrafico en las correlaciones internacionales del Ediacarico terminal, asi como para futuras reconstrucciones paleobiogeograficas y paleoecologicas. EnglishIt is herein presented the unprecedented occurrence of Cloudina carinata Cortijo et al., 2010 in the American continent. This new occurrence expanded the geographic distribution of this species, until now reported from sections in Spain and Siberia. The assembled biomineralizing metazoans Cloudina carinata, Cloudina lucianoi (Beurlen & Sommer, 1957) and Corumbella werneri Hahn et al., 1982 are presented for the first time from the Tamengo Formation, Corumba Group, Porto Figueiras section, Corumba Municipality, Mato Grosso do Sul State, Brazil. This new occurrence could be employed as an additional biostratigraphic tool for international correlation of the terminal Ediacaran, as well as for palaeobiogeographic and palaeoecologic reconstructions.
