• Resumen

  • Recent field work carried out to the west of Purmamarca (Jujuy province) focused the type area of the "Sepulturas limestones" (Harrington, 1957). Levels bearing Pliomeridius sulcatus Leanza and Baldis associated with Hoekaspis" schlagintweiti, molluscs, brachiopods, and trace fossil are located close to La Ciénaga locality. The collected material together with some previously registered fossils, as well as other recently described specimens from Cajas region (Aceñolaza and Aceñolaza, 2002) lead us to re–state some stratigraphic and chronological concepts that nowadays are confusing due to the poor knowledge of the strata croping out in the type–area of the Sepulturas Formation, nearby La Ciénaga locality, by the international route to Chile.
