Abstract

From deposits ascribed bivalves and gastropods "entrerrian transgression" are compared by mean of clustering analysis, diversity, trophic mode and mode of life. It is mainly concluded that Paraná-Colonia and Chuy-Cuenca de Pelotas are the areas more closeley related. Buenos Aires has certain affinities with Paraná Colonia, whilst the relationships of these to the northem Patagonia area are not clear. A stable shalow marine enviroment is inferred, except for the Chuy area where one involving higher energy level is suggested.
