Ordovician Echinoderms of Argentina

Authors: Aceñolaza, Guillermo F.; Gutiérrez-Marco, J. C.;

Ordovician Echinoderms of Argentina

Abstract

[ES] El registro de equinodermos ordovícicos en la República Argentina está limitado a los pelmatozoos, sin que se haya abordado aún el estudio detallado de los mismos. Los fósiles suelen aparecer fragmentariamente como placas tecales aisladas y segmentos columnares, siendo escasos los ejemplares completos. Entre los taxa reconocidos se cita a Macrocystella sp.; Macrocystella? durandi Aceñolaza y Lingulocystis cf. elongata Thoral. Complementando al conocimiento de los pelmatozoos ordovícicos, se figura material de algunas nuevas localidades fosilíferas de la Cordillera Oriental, así como del Sistema de Famatina y la Precordillera. En base a su registro cronoestratigráfico desde el Cámbrico Superior en las plataformas de la Cuenca Central Andina, se plantea una posible radiación temprana del grupo en la región, con una posterior migración hacia otros sectores en el margen Gondwánico.

[EN] The record of Ordovician echinoderms in Argentina is restricted to the Pelmatozoans, and has not been deeply studied yet. They commonly appear as fragmentary samples represented by isolated ossicles as thecal plates and columnals with the exception of a single locality with few complete specimens. Among the recognized taxa are: Macrocystella sp., Macrocystella? durandi Aceñolaza and Lingulocystis cf. elongata Thoral. In addition, a variety of unidentified stem and cup plates from six new localities of the Cordillera Oriental, the Famatina System and the Precordillera are illustrated. An early radiation of the group is inferred from the Central Andean Basin, with a posterior migration to other sectors of Gondwana.

This paper was finished thanks to the financial support of Fundación Antorchas and the Instituto Superior de Correlación Geológica (CONICET-UNT, Argentina), being also a contribution to the project “Dinámica faunística perigondwánica” of the current Scientific Cooperation Program between Spain and Argentina.
