Resumen:
Abstract. UPPER PALEOZOIC FROM ARGENTINA: A COMPLETE FOSSILIFEROUS RECORD IN WESTERN GONDWANA.
Thick Lower Carboniferous up to Permian sequences are recognized in the extensive Argentinian basins.
These strata contain varied and abundant fossiliferous assemblages that include marine and continental
invertebrates, plant remains, palynomorphs and ichnofossils, occasionally accompanied by fish scales and
estromatolites. The diversity of invertebrates and the usefulness of palynomorphs for stratigraphic correlations
is relevant at both, local and regional scale. Early Carboniferous assemblages are characterized by
herbaceous lycophytes and pteridosperms, together with marine invertebrates and palynological associations
characterized by taxa of biostratigraphic regional significance. Late Carboniferous sedimentation began
with glacigenic deposits followed by postglacial intervals showing the incoming of theUPPER PALEOZOIC FROM ARGENTINA: A COMPLETE FOSSILIFEROUS RECORD IN WESTERN GONDWANA.

characterized by taxa of biostratigraphic regional significance. Late Carboniferous sedimentation began
with glacigenic deposits followed by postglacial intervals showing the incoming of the
Nothorhacopteris-Botrychiopsis-Ginkgophyllum flora and monosaccate pollen in the palynological records.
Transgressive facies characterized the Late Carboniferous-Early Permian boundary where marine invertebrates
are usually found. Early Permian flora contains the first glossopterid leaves associated to abundant
conifers and ferns whereas marine environments were dominated by bivalves and brachiopods.
Palynological assemblages are characterized by taeniate pollen grains.flora and monosaccate pollen in the palynological records.
