“…However, a critical taxonomic revision of all these taxa is urgently needed to clarify their status, prospective phylogenetic placement, and validity. Multiple fossil species recovered from the Pleistocene deposits 98 should be compared with recent representatives of the corresponding genera, as many of these nominal taxa may be synonyms of terminal species or their stem lineages 33,101,102 .…”

freshwater mussels are ecosystem engineers and keystone species in aquatic environments. Unfortunately, due to dramatic declines this fauna is among the most threatened globally. Here, we clarify the taxonomy and biogeography of Russian Unionidae species based on the most comprehensive multi-locus dataset sampled to date. We revise the distribution and assess the conservation status for each species. This fauna comprises 16 native species from 11 genera and 4 tribes: Anodonta, Pseudanodonta (Anodontini); Amuranodonta, Beringiana, Buldowskia, Cristaria, Sinanodonta (cristariini); Middendorffinaia, Nodularia, Unio (Unionini); and Lanceolaria (Lanceolariini). no countrylevel endemic species are known in Russia, except for Buldowskia suifunica that may also occur in china. Sinanodonta woodiana, a non-native species, was introduced from china. Russia comprises the northern parts of Western and Eastern Palearctic subregions. The first subregion with six species encompasses a huge area from the western boundary of Russia to the Lena Basin in Siberia. the second subregion with 10 species covers the Amur Basin, rivers east of the Lena Basin, coastal basins of the Japan Sea, and the North Pacific Islands. The fauna of Russia primarily includes widespread generalist species that are here considered Least concern (Lc). However, Buldowskia suifunica and Sinanodonta lauta have restricted distributions and are assessed here as Vulnerable (VU) and endangered (en), respectively. Freshwater mussels (order Unionida) are ecologically and economically important aquatic animals 1 that are sensitive to water pollution, habitat loss, climate changes, and other negative anthropogenic and natural impacts 2-4. These animals are widely distributed throughout Russia, representing keystone taxa in various water bodies of European Russia, Siberia, and the Russian Far East (mainland, Sakhalin, and Kurile Archipelago) 5. However, freshwater mussels are not known to occur in the Polar Urals, Yamal and Taymyr peninsulas, Arctic Ocean

“…Its larvae parasitize salmonids, the most suitable hosts for them being the brown trout and Atlantic salmon, and less suitable, the European taimen (see [83] and references therein). The extinct species M. arca Tshepalyga, 1964, which inhabited the Black Sea basin in the Upper Pliocene and Early Pleistocene, is considered to be the ancestor of M. margaritifera [84][85][86].…”

“…However, the spread of cold-water aquatic organisms into the Mediterranean from the area of the present-day Black Sea in the later period (Neogene-Quaternary) was, apparently, difficult or even impossible. Most likely, this is why neither European taimen nor margaritiferid mussels parasitizing salmonids migrated to the Mediterranean, although both groups, according to paleontological data, already lived in the area of the modern Black Sea basin at that time [80,[84][85][86]. Our study of the mitochondrial COI gene diversity has demonstrated that the brown trout populations of the Black and Caspian seas are characterized by different groups of haplotypes, whereas the Mediterranean populations of this species have the haplotypes found in the Caspian basin (or those directly originating from them).…”

Analysis of zoogeographic, paleogeographic, and molecular data has shown that the ancestors of many fresh- and brackish-water cold-tolerant hydrobionts of the Mediterranean region and the Danube River basin likely originated in East Asia or Central Asia. The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose. Some of the forms that originated in the Paratethys colonized the Mediterranean, and overwhelming data indicate that representatives of the genera Salmo, Caspiomyzon, and Ecrobia migrated during the Miocene from the region of the modern Caspian through the Araks Strait, which existed at that time. From the Ponto-Caspian and the Mediterranean regions, noble salmon, three-spined stickleback, European pearl mussel, seals, and mollusks of the genus Ecrobia spread to the Atlantic Ocean and colonized the Subarctic and Arctic regions of Europe and North America. Our study indicates that the area of the former Paratethys retains its significance as a center of origin of new species and genera and that it has been the starting point of migration “corridors” up to the present time.

“…The most common fluvial mussel, Pseudunio flabellatiformis, is well-known from the fluvial deposits of the Pannonian Basin throughout the entire late Miocene (as "Unio wetzleri" or "Margaritifera flabellatiformis" in the older literature; here we follow the revision of Lyubas et al 2019); thus, it does not constrain the age of FA5 and FA6 occurrences. In Derșida and in the lignite-bearing deltaic layers of Derna, however, Anancus arvernensis remains were found (Codrea and Margin 2009;Gasparik pers.…”

Sedimentary successions exposed at basin margins as a result of late-stage inversion, uplift and erosion usually represent only a limited portion of the entire basin fill; thus, they are highly incomplete records of basin evolution. Small satellite basins, however, might have the potential of recording more complete histories. The late Miocene sedimentary history of the Șimleu Basin, a north-eastern satellite of the vast Pannonian Basin, was investigated through the study of large outcrops and correlative well-logs. A full transgressive–regressive cycle is reconstructed, which formed within a ca. 1 million-year time frame (10.6–9.6 Ma). The transgressive phase is represented by coarse-grained deltas overlain by deep-water lacustrine marls. Onset of the regressive phase is indicated by sandy turbidite lobes and channels, followed by slope shales, and topped by stacked deltaic lobes and fluvial deposits. The deep- to shallow-water sedimentary facies are similar to those deposited in the central, deep part of the Pannonian Basin. The Șimleu Basin is thus a close and almost complete outcrop analogue of the Pannonian Basin’s lacustrine sedimentary record known mainly from subsurface data, such as well-logs, cores and seismic sections from the basin interior. This study demonstrates that deposits of small satellite basins may reflect the whole sequence of processes that shaped the major basin, although at a smaller spatial and temporal scale.
