“…According to Newell et al (2010), the study area represents part of a distal fluvial distributary system in the west of the Ural Mountains. More specifically, this paleoenvironment was discussed by Sennikov and Golubev (2012, p. 317) as “an extensive river lowland with a system of channels of constant and temporary streams alternating with sandy and marshy oozy banks and somewhat elevated areas.” Details of both lithology and lithofacies of the study area (i.e., sections at the Zhukov Ravine, Bykovka, Sokovka, Balymotikha, Fedurniki sand pit, Arefino Ravine, and Staroe Slukino) were repeatedly described in recent publications (e.g., Newell et al, 2010; Golubev et al, 2012a, b; Owocki et al, 2012; Sennikov and Golubev, 2012; Lebedev et al, 2015; Scholze et al, 2015; Bajdek et al, 2016; Niedźwiedzki et al, 2016) and therefore are only briefly summarized here.Figure 2Stratigraphy, lithology, and fossil content of the studied late Permian–Early Triassic sections near the towns Vyazniki and Gorokhovets in the Moscow Syneclise, European Russia.

“…2). According to the lithostratigraphic subdivision of Golubev et al (2012a, b), Lebedev et al (2015), and Scholze et al (2015), the Obnora Formation is subdivided into three units (Voinovo, Uglich, Gorokhovets members), and the overlying Vokhma Formation is subdivided into two units (Zhukov and Ryabi members). Depending on the geographic position, members of both formations can locally be absent because of local facies changes or due to temporary erosion (Lebedev et al, 2015, p. 1117).…”

“…Among these, the key sections of the late Permian–Early Triassic continental deposits of the Moscow Syneclise near the towns of Vyazniki and Gorokhovets (Vladimir Region, European Russia) (Fig. 1) have been increasingly studied for sedimentology (e.g., Newell et al, 2010), lithostratigraphy (Golubev et al, 2012a, b), magnetostratigraphy (Balabanov et al, 2016), paleobotany (e.g., Naugolnykh, 2005; Krassilov and Karasev, 2008, 2009; Karasev, 2013), insects (e.g., Aristov et al, 2013), ostracods (e.g., Lozovsky and Kukhtinov, 2007; Kukhtinov et al, 2008; Molostovskaya, 2010; Voronkova, 2014), conchostracans (e.g., Scholze et al, 2015), bivalves (Silantiev, 2014, 2016), fishes (Minikh et al, 2014, 2015a, b; Lebedev et al, 2015), and tetrapods (e.g., Sennikov and Golubev, 2005, 2006, 2012), including vertebrate coprolites (e.g., Owocki et al, 2012; Bajdek et al, 2016, 2017; Niedźwiedzki et al, 2016; Sennikov, 2017).

The Moscow Syneclise on the East European Platform is an important area for the study of the continental biota of late Permian to Early Triassic age in continuous sections. This study attempts a taxonomic description of the late Permian conchostracan fauna of this area. The rich, new material was collected, bed by bed, during geological and paleontological excavations of lacustrine and fluvial deposits of the Obnora Formation and Vokhma Formation of the late Permian Zhukovian Regional Stage near the towns of Vyazniki and Gorokhovets. The conchostracan fauna of the Zhukovian Regional Stage consists predominantly ofPseudestheriaand less frequently ofPalaeolimnadiopsis. In the earliest Triassic Vokhmian Regional Stage, a more diverse fauna includingEuestheria,Magniestheria,Cornia,Palaeolimnadiopsis, andRossolimnadiopsiswas already recorded. The preliminary taxonomic determination of the pseudestheriids from the Zhukovian Regional Stage is intended to serve as a prerequisite for future studies of late Permian conchostracan biostratigraphy on the regional to interregional scale.
