Abstract

"The discovery of mammals from the Río Loro Formation, Early Tertiary of Tucumán Province, Argentina, is reported, along with a brief outline of the geology of this area. Some taphonomic characteristics are discussed. A preliminary description and discussion about Eoastrapostylops riolorense n.g. et. n.sp. is given. Its features suggest that it is a primitive member of Astrapotheria Order, probably representing a stock ancestral to both the Astrapotherioidea and the Trigonostylopoidea (as Suborder ): Eoastrapostulops is presented as the type of a new Family Eoastrapostylopidae. The Río Loro Formation is considered to be Paleocene in age, with its lower section tentatively correlated with the Mealla Formation (Santa Bárbara Subgroup).
