“…Remarks. — Cryptomactra pesanseris has been recorded from the Taman Trough, eastern part of the Kerch Peninsula, Taman Peninsula, and Ciscaucasia, Russia, defined by Cryptomactra beds (Kolesnikov, 1940; Rostovtseva, 2009). The basin includes a molluscan community of Cryptomactra pesanseris (Kolesnikov, 1940) accompanied by both benthic and planktonic diatom species.…”

All genera based on fossil type species belonging to the family Mactridae are alphabetically listed in this work. The oldest records of the Mactridae come from Cretaceous deposits of North America. However, this group of bivalves has been worldwide recorded from the Paleogene and Neogene. An emended diagnosis for each genus is herein provided. In addition to that, type species, type localities, and occurrences are included. For each genus, a remarks section includes the most recent published taxonomic opinions. Nevertheless, in some cases, new taxonomic decisions based on morphological analysis of types have been taken. Genera based on extant type species are excluded from this work. Forty-five genera are listed herein and type material has been reproduced wherever possible. Ionesimactra nom. nov. is proposed as a replacement name for Caspimactra Ionesi (non Caspimactra Ali-Zade and Kabakova). This work constitutes the basis for future revisions related to fossil taxa of the family Mactridae from different regions. UUID: https://zoobank.org/ccc72130-4ea2-44a9-add9-51cfce58f2d5

“…If sediments accumulated from 7.7 to 8.6 Ma, the Lower Maeotian should correspond to chrons C4n.2n and C4r and contain a significant hiatuses with the total duration of not less than 0.4 Ma (i.e., about half of the entire period of the Early Maeotian). The presence of these significant hiatuses in the relatively deep-water deposits of the Lower Maeotian of of the Popov Kamen section was not established based on the available paleontological and lithological data (Rostovtseva and Goncharova, 2008, Rostovtseva, 2009a, Trubikhin and Pilipenko, 2011, Radionova et al, 2012.…”

The stratigraphic scale of the Eastern Paratethys is revised based on a study of the Neogene stratotype and reference sections, their biotic characteristics, and paleomagnetic and sedimentological data. New data on the correlation of its regional subdivisions with the Central Paratethys and Mediterranean stratotypes are presented. The section "Regional Stage Scale of the Eastern Paratethys" considers the history of identification and a brief description of the horizons of the regional scale, which later became regional stages, as well as their historical stratotypes and lectostratotypes, and division into Beds and Substages. The section "History of Separate Biota Groups" provides reviews on the most important groups of fauna, phytoplankton, and terrestrial vegetation, as well as on magnetostratigraphy, the possibility of correlation and dating of sections based on these data, and comparison with the Central Paratethys and stratotypes of the Mediterranean. In conclusion, the main results of the revision of the stratigraphic scheme of the Neogene of the Eastern Paratethys are given.

“…Overall, several studies were carried out in the Eastern Paratethys more recently, but we cite here only a selection. Rostovtseva (2009) reported “algal–nubecularian limestones” from the Kerch Peninsula without specifying the algae. Koleva‐Rekalova & Darakchieva (2017) described for the first time Nubecularia novorossica from NE Bulgaria (Figure 2), which occur in beds of 5–30 cm thickness in rock forming quantities and comprises two morphotypes ( solitaria and nodula) .…”

Nubecularia bioherms represent unique bioconstructions that are restricted to the upper Serravallian of the Paratethys and have been reported since the 19th century. They occur in the Central Paratethys in the late Sarmatian and the Eastern Paratethys in the Bessarabian both regional stages of the respective Paratethyan areas. In this study, several locations in the Vienna and Styrian basins of the Central Paratethys were studied out of which four localities were documented in detail (Wolfsthal, Maustrenk, St. Margarethen—Zollhaus, Vienna—Ruzickagasse) to reconstruct their sedimentary setting, their internal composition, and their indications of environmental parameters. The detailed studies included logging of outcrop sections, petrographic, facies and biotic analyses of polished slabs and thin sections and also cathodoluminescence analyses. These concluded that these bioconstructions are not only composed of the foraminifer Nubecularia but represent a complex mixture and interrelationships of Nubecularia, serpulids and microbial carbonate. Four boundstone types can be differentiated: Nubecularia boundstone, Nubecularia‐coralline algal boundstone, stromatolitic/thrombolitic boundstone and serpulid‐nubeculariid‐microbial boundstone. The first 3 types are characteristic of specific localities; the fourth type occurs in all studied locations and represents the terminal association on top of the three other types. The three basal boundstones are predominantly of columnar growth form irrespective of dominance of Nubecularia, coralline algae or microbial carbonate, and the terminal boundstone is widely irregularly organized. The general depositional environment is characterized by cross‐bedded oolitic grainstones with abundant quartz grains, miliolid foraminifers and mollusks. Intercalated are microbial carbonates mostly stromatolites but also thrombolites. This indicates a general high water energy environment interrupted by more calm periods when the microbial carbonate was built. The 3 basal types of bioconstructions are interpreted to reflect decreasing food supply and/or oxygenation from Nubecularia over Nubecularia‐coralline algal to stromatolitic/thrombolitic boundstone. The serpulid‐nubeculariid‐microbial boundstone reflects an internal succession with a decrease of the same parameters. Water depth is considered very shallow ranging from 0 to a few meters, and salinity was normal marine to hypersaline. The reconstructed paleoenvironment with dominating oolite shoals and seagrass meadows was not restricted to the Central Paratethys but extended over the entire Paratethys and represented the largest oolite facies area of the entire Cenozoic!
