Resumen:

At the moment, two freshwater bivalve species were described for the continental Jurassic of Patagonia: Diplodon simplex Morton and Diplodon matildensis Morton from La Matilde Formation of the Santa Cruz province. The Cañadón Asfalto Formation located in Chubut province exhibits a high diverse invertebrate fossil fauna preserved mainly in lacustrine facies, which includes clam shrimps, bivalves, gastropods, ostracods and insects. However, few studies have been carried out on freshwater bivalve of this geological unit. In this work, a morphological description of bivalve assemblage and paleoenvironment analysis from the Cañadón Asfalto Formation was performed. Forty samples were collected from three stratigraphic levels at the Cañadón Asfalto locality. These levels are ash fall tuffs rich in glass particles accumulated in a lacustrine system with development of microbial activity. Morphological analyzes of outline and sizes were performed at each level. Our results showing the smallest-sized association of unionids recorded for the Jurassic time with size ranging from 7.6-11.7 mm long and 5.2-7.6 mm high. The environmental influence of pyroclastic falls could have played an important role in the development of the sizes of populations and shells.


Actualmente se han descrito dos especies de bivalvos de agua dulce para el Jurásico continental de la Patagonia: Diplodon simplex Morton y Diplodon matildensis Morton de la Formación La Matilde en la provincia de Santa Cruz. La Formación Cañadón Asfalto ubicada en la provincia de Chubut exhibe una fauna fósil de invertebrados muy diversa conservada principalmente en facies lacustres, que incluyen “conchostracos”, bivalvos, gasterópodos, ostrácodos e insectos. Sin embargo, se han efectuado pocos estudios sobre los bivalvos representados de esta unidad geológica. En este trabajo se realizó una descripción morfológica de restos de conchillas de bivalvos y el análisis del paleoambiente de la Formación Cañadón Asfalto. Se recolectaron cuarenta muestras de tres niveles estratigráficos en la localidad de Cañadón Asfalto. Estos niveles son tobas de caída de ceniza, ricas en partículas de vidrio acumuladas en un sistema lacustre con desarrollo de actividad microbiana. Se hicieron análisis morfológicos de contorno y tamaños en cada nivel. Nuestros resultados muestran la asociación de uniónidos de menor tamaño registrada para el Jurásico, con tamaños que oscilan entre 7,6 y 11,7 mm de largo y entre 5,2 y 7,6 mm de alto. La influencia ambiental de la caída de material piroclástico podría haber jugado un papel importante en el desarrollo de los tamaños de las poblaciones y conchillas.
