Groeber and the triassic in Argentina

Pablo Groeber´s contributions to characterize the Triassic of Argentina and, in particular, the chapter about the System included in the book Geografía de la República Argentina, written in co-authorship with Pedro Stipanicic, are discussed. A binary division for the Argentine Triassic is originally...
