Abstract

"Eoastrapostylops riolorense Soria and Powell, 1982 is considered the most primitive astrapothere known. It was found in the lower section of the Río Loro Formation, referred tentatively to Middle Paleocene, at Tucumán Province, Northwestern Argentina. The recently Itaborain Land Mammal Age, recognized by Marshall (1985) is considered lacking of valid basis. A detailed description of type specimens is given. Careful comparisons with both Paleocene and Eocene Astrapotheria are made too. This first part constitute the basis for the second part, which will refer on affinities, origin, and early evolution of the Astrapotheria."
