ABSTRACT
Venezuela, due to having been located near the equator (0-10ºS) during the Late Pensylvanian, did not have the influence of the permo.carboniferam glaziation that affected to other more southern portions of the Gondwana paleocontinent. For this reason and due to having been one of the most close areas of the Gondwana to Laurasia’s paleocontinent, it is expected that the vegetation that developed during the interval between Late Carboniferous to the Early Permian was closely related to the paleofloras belonging to Laurasia known till now in the Euroamerican’s Provínce. After the study of the specimenes gathered in the Carache’s Formation Outcrop, located at kilometer 16 of the Carache-Agua de Obispo way, could be identified the following species: Sphenophyllum sp., Annularia cf. A. stellata (Schlotheim) Wood, Lobatopteris vestita (Lesquereux) Wagner, Neuropteris ovata Hoffmann y N. scheuchzeri Hoffmann; in addition to Protoblechnum sp., formerly gathered in the Quebrada Mucuchaché outcrop (Palmarito’s Formation of the Early Permian). All of them well known in other formations of the same periods in Europe and North America.
