| The Aquidauana Formation is a Permo-Carboniferous sedimentary unit, widely stratigraphicaly distributed in the northwestern and northern portions of the Paraná Basin. However, little paleontological data is available from this formation, preventing accurate biostratigraphic and paleoecological interpretations. An abundant, diversified and well preserved assemblage of palynomorphs was recognized from sampling conducted in an outcrop section in Cipolândia District of Aquidauana Municipality, state of Mato Grosso do Sul, Brazil. A total of 35 indigenous palynomorph taxa was recognized, comprising 6 species of spores (related to 5 genera), 28 species of pollen grains (14 genera) and 1 species of chlorophycean algae. Monosaccate pollen grains are exceptionally... |

| The analysis of early Kasimovian (Pennsylvanian) brachiopod assemblages from two fossiliferous localities of the Las Llacerias Formation (Ándara Massif, Picos de Europa, northern Spain) improve our knowledge of this fossil group in the Cantabrian Zone. At the Morra de Lechugales Peak (locality 1), marlstones and bioclastic limestones, accumulated in a low energy, subtidal, aphotic setting, characterize a soft muddy sea-floor affected by periodic intense bottom currents and provide a rich assemblage of brachiopods together with other macrofossils. Brachiopod specimens are characterized by their small size (<10 mm) and belong to 38 different taxa. The fossiliferous dark marly limestones at the Castillo del Grajal (locality 2) record a very shallow water,... |
