“…Within the Gondwanan Realm, Palaeomutela s.l. is known from the Capitanian of Parana Basin (Brazil) (Guerrini et al 2020), Falkland Islands (Simoes et al 2012 and Kilombero Rift Valley (Tanzania) (Cox 1932(Cox , 1936. During the Lopingian, it is widespread in the Ruhuhu Basin (Tanzania) (Cox 1932(Cox , 1936, the Zambezi Basin (Kenya) (Gregory 1921;Weir 1938), the Luangwa Basin (Malawi) (Jones 1890;Newton 1910), the mid-Zambezi Basin (Hind 1903;Bond 1946;Bond 1954), the Main Karoo Basin (Amalitzky 1895;Rilett 1975), and the Ohio Range of the Horlick Mountains (Antarctic Platform) (Bradshaw 1984).…”

Non-marine bivalves are key fossils in Permian continental stratigraphy and palaeogeography. Although known since the end of 19th century, the occurrences from the continental basins of the Southern Alps have never been extensively studied. The non-marine bivalves from the Lower Permian Collio Formation (Brescian pre-Alps) are herein revised, and those from the Guncina Formation (Athesian District) are described for the first time. These two units yielded non-marine bivalves belonging to the genus Palaeomutela sensu lato, which is widespread in the Permian continental successions of eastern Euramerica. Three Palaeomutela morphotypes have been herein described: oval-subtriangular, subtrapezoidal and elongated. The latter includes several specimens herein assigned to Palaeomutela (Palaeanodonta) berrutii sp. nov. and dominates the Collio Formation association. The Guncina Formation yielded also the genus Redikorella, for the first time co-occurring on the same stratigraphic horizon of Palaeomutela, herein assigned to Palaeomutela (Palaeanodonta) guncinaensis sp. nov. To-date, it was generally accepted that the first members of the genera Palaeomutela and Redikorella occurred during the Ufimian (late Kungurian of the global scale) in the non-marine basins of the Cis-Ural Foredeep and of Angara, respectively. Such new finds in the early-middle Kungurian of southwestern Europe, well constrained by radioisotopic dating, suggest new global first appearance (First Appearance Datum) and a possible new center of origin of these genera. This fact raises new questions on biostratigraphy, palaeobiogeography and palaeoecology, which will require further research. If we assume that the genera Palaeomutela and Redikorella had only one center of origin, we need to hypothesise possible migration routes from SW Europe to the continental basins of Eastern Europe and Angara. Apparently, such migration could be better supported by a Pangaea B palaeogeographic configuration.

“…The Serra Alta Formation represents its maximum marine influence, and the overlaid Teresina Formation registers pelites with tide influenced structures, which characterizes the inception of new ecological conditions (Milani et al, 2007). According to Simões et al (2017) and Guerrini et al (2020), these processes represent the establishment of a confined epeiric sea, followed by a trend of shallowing and continentalization in the basin. In marginal areas of this epeiric sea, several types of environments with variable salinity gradients might have been established (Ng et al, 2019), such as estuaries, bays, lakes, lakes with occasional marine influence, and lagoons as discussed by Bennett et al (2011).…”

New ostracod species are described for Middle to Upper Permian (Guadalupian) rocks of the Teresina Formation, Paraná Basin, from two localities in the São Paulo State, southwestern Brazil: Xavante Dam and Pau Preto Quarry. Paranacythere nigripallus gen. nov. and sp. nov., Velatomorpha xavante sp. nov., and Velatomorpha pseudoaltilis sp. nov. are herein described. The association Velatomorpha–Paranacythere is proposed as typical of Permian mixohaline environments of the Teresina Formation, and is the most abundant in the two studied localities. Paranacythere nigripallus gen. nov. and sp. nov. is proposed to accommodate a very abundant species with typically cytheroidean characteristics, and tentatively ascribed to the family Cytheruridae. Some ecological remarks are presented based on ostracod population age structure, biostratinomy and taxonomic composition of assemblages. The diagnosis of Velatomorpha Tibert & Dewey is emended. Keywords: evolution, marginal marine environments, paleoecology, Teresina Formation, taxonomy.
