“…As a group of south‐east Mediterranean origin, the ancestors of Alopia could have colonized the Carpathians via the land contact formed between the Southern Carpathians and the Balkan Mountains, disrupting the continuity of the receding Paratethys. This geological transformation took place around the Pliocene–Pleistocene boundary, dated to 2.6 Mya (Olteanu & Jipa, ; Andreescu et al ., ), suggesting that the appearance and expansion of Alopia must be more recent events. This assumption is in line with the lack of Alopia in the Early Pleistocene cave deposits of the Şprenghi Hill at Braşov (Soós, ), and also with the Late Pleistocene dating of fossil Mastus venerabilis (Pfeiffer, 1853), a species of the Enidae arriving at the Carpathians from the same direction, and preferring the same habitats as Alopia , found in loess samples of south‐eastern Hungary (Soós, ).…”

Whereas the vast majority of gastropods possess dextral shell and body organization, members of the Clausiliidae family are almost exclusively sinistral. Within this group a unique feature of the alpine genus Alopia is the comparable representation of sinistral and dextral taxa, and the existence of enantiomorph taxon pairs that appear to differ only in their chirality. We carried out a molecular phylogenetic study, using mitochondrial cytochrome c oxidase subunit I (COI) gene sequences, in order to find out whether chiral inversions are more frequent in this genus than in other genera of land snails. Our results revealed multiple independent inversions in the evolutionary history of Alopia and a close genetic relationship between members of the enantiomorph pairs. The inferred COI phylogeny also provided valuable clues for the taxonomic division and zoogeographical evaluation of Alopia species. The high number of inverse forms indicates unstable fixation of the coiling direction. This deficiency and the availability of enantiomorph pairs may make Alopia species attractive experimental models for genetic studies aimed at elucidating the molecular basis of chiral stability.

This paper studies the Porat Formation (Fm.), which was deposited along the NE margin of the Dacian Basin part of the East Carpathian foreland (ECF) during the Pliocene and Early Pleistocene. We use a review of stratigraphic data in combination with lithofacies and sedimentary architecture analysis to interpret the Porat Fm. as a large sandy alluvial basin infill with an aggradational structure, consisting of cyclic successions of shallow sandy high-energy braided rivers. Aggradation of the Porat Fan was governed by subsidence of the Dacian Basin, along with a northerly supply of water and sediment from the Carpathians. Along the southern margin of the area the fan entered the Reni–Izmail-Trough, which formed the periodically active gateway between the Black Sea and Dacian basins. Along this trough, the Porat Fm. is developed in a different facies, discerned as the Dolynske Member (Mb. 1), which accumulated in the channel of a large river interpreted as the paleo-Danube. According to mammal stratigraphy of the Porat Fm. this continental-scale river had reached the area by the Gelasian to early Calabrian. The Porat alluvial infill indicates a stable water supply from the Carpathians, which explains the ecologically mixed fauna in its deposits: moistened forested alluvial plain-valleys were present between the zonally semi-arid steppe interfluves. The Porat Fm. and the previously studied late Miocene Balta Fm. are key elements for further in-depth study of the terrestrial evolution (tectonic–sedimentary–relief) of the ECF and north-western Black Sea coastal regions.

“…In this contribution a new biozonation based on brackish andfreshwater molluscs and mammalian faunas made it possible to propose a set of new regional chronostratigraphic units (Andreescu et al, 2013). The paper of Yanina (2013) summarizes the intricate history of the Caspian Sea transgressions and regressions in Middle to Late Pleistocene and elaborates a mollusc-based biostratigraphy for this important region.…”
