The Palaeozoic basins of western and north-western Argentina display thick sequences that bear witness to the evolution of the south-western margin of Gondwana during Late Palaeozoic times. One of the most singular characteristics of these sequences is their abundant biostratigraphic record that includes remains of plants, marine invertebrates and varied palynological associations. These materials allowed defining biostratigraphic schemes (for a discussion of this, see Archangelsky, 1996), many of which can be used to make continental scale correlations (Archangelsky and Cúneo, 1984; Césari and Gutiérrez, 2001). Nevertheless, the studies of Upper Palaeozoic fossil woods in Argentina are few and far between, with the exception of the anatomical studies carried out by Archangelsky (1960), Brea and Césari (1995) and Pujana and Césari (in press). Therefore, the anatomy of woody species from this part of Gondwana during Carboniferous and Permian times is not known in detail.
