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 carbonate nodules from Montañez et al., (2007) utilized in this study were collected from well-developed and drained paleosols from: 1) the Eastern Shelf of the Midland Basin (N.C. Texas), 2) Paradox Basin (S.E. Utah), 3) Pedregosa Basin (S.C. New Mexico), 4) Anadarko Basin (S.C. Oklahoma), and 5) the Grand Canyon Embayment (N.C. Arizona) (Fig. 1a; Richey et al., (2020)). The plant cuticle fossils come from localities in: 1) N.C. Texas (Lower Pease River [LPR], Lake Kemp Dam [LKD], Parkey's Oil Patch [POP], and Mitchell Creek [MC]; all representing localities that also provided carbonate nodules or plant organic matter [POM] for Montañez et al., (2007), 2) N.C. New Mexico (Kinney Brick Quarry [KB]), 3) S.E. Kansas (Hamilton Quarry [HQ]), 4) S.E. Illinois (Lake Sara Limestone [LSL]), and 5) S.W. Indiana (sub-Minshall [SM]) (Fig. 1a, S2-4; Richey et al., (2020)). These localities span a wide portion of the western equatorial portion of Euramerica during the latest Pennsylvanian through middle Permian (Fig. 1b). S2 Biostratigraphic Correlations and Age Model N.C. Texas stratigraphy and the position of pedogenic carbonate samples from Montañez et al., (2007) and cuticle were inferred from N.C. Texas conodont biostratigraphy and its relation to Permian global conodont biostratigraphy (Tabor and Montañez, 2004; Wardlaw, 2005; Henderson, 2018). The specific correlations used are (C. Henderson, personal communication, August 2019): (1) The Stockwether Limestone Member of the Pueblo Formation contains Idiognathodus isolatus, indicating that the Carboniferous-Permian boundary (298.9 Ma) and base of the Asselian resides in the Stockwether Limestone (Wardlaw, 2005). (2) The Gouldbusk Limestone Member of the Moran Formation contains a conodont that is likely in the I. whitei zone. This conodont is also found in the Neva Limestone of Kansas and indicates a mid-to late Asselian age (~295 Ma; Wardlaw, (2005)). (3) The Santa Anna Branch Shale and Coleman Junction Formations of the Cisco Gp contain Sweetognathus merrilli, indicating that these two formations span the range of occurrence of S.

Isolated capsule-like reproductive organs from the upper Permian of the Southern Alps, NE Italy, are described as Brinkia gen. nov. Two species have been distinguished, i.e. Brinkia kerpiana sp. nov. and B. cortianensis sp. nov. Brinkia capsules resemble in gross morphology single valves of the Leptostrobus-type, Mesozoic reproductive organs belonging to the Czekanowskiales. A czekanowskialean affinity is reinforced by the fact that the Brinkia remains are found associated with straplike leaves resembling those of Czekanowskia. This would expand the record of the Czekanowskiales to the Wuchiapingian (early Lopingian) and suggests that, during the arid late Permian climate, representatives of the order could occupy the more humid habitats within the deltaic floodplain formed during a sea-level rise.
