Scaphopods from the lower Badenian (Miocene) strata of the southwestern part of the Carpathian Foredeep in Moravia and its denudation relics on the Bohemian Massif are described, by means of fieldwork and re-examination of comparative material from the depositories of the Moravian Museum and the Department of Geological Sciences, Faculty of Science, MU Brno. In total, 8 species belonging to 6 genera were found. Occurrences of Entalina tetragona, Gadila ventricosa, Omniglypta jani, Fissidentalium badense, Antalis mutabilis, Antalis fossilis, and Paradentalium michelottii were confirmed and Omniglypta emersoni was newly recorded. Both the molluscs and lithofacies prove that the species inhabited two environments: infralittoral – Gadila ventricosa, Antalis fossilis, Omniglypta jani and Omniglypta emersoni; and circalittoral – Entalina tetragona and Antalis mutabilis. Fissidentalium badense was present in both circalittoral and infralittoral localities, so its greater depth range can be presumed. Paradentalium michelotii only occurred in the Borač locality, where circalittoral and infralittoral faunas were mixed; due to their slight abrasion, these shells were probably redeposited into the circalittoral environment from shallower (infralittoral) waters.

The well-known Pleuronectia badensis Fontannes, 1882 (currently classified as Cristatopecten cristatus badense) is declared as a nomen protectum against the older synonym Pecten burdigalensis var. polonica Pusch, 1837 considered a nomen oblitum. It ranges from the early to the late Miocene (Burdigalian–Messinian) of the NE Atlantic and Mediterranean. In the Central Paratethys it appeared in the early Miocene (Karpatian, correlating with the latest Burdigalian) and became extinct in the middle Miocene (Late Badenian, correlating with the early Serravallian). In Poland – the northernmost part of Central Paratethys – the occurrence of this taxon is limited to the late Early Badenian (late Langhian).

Over three thousand specimens representing the superfamily Trochoidea Rafinesque, 1815 [Trochidae Rafinesque, 1815 and Calliostomatidae Thiele, 1924 (1847)] from the upper Upper Badenian = Kosovian = lower Serra vallian (middle Miocene) marine deposits of Ukraine, housed in the collections of the Polish Academy of Sciences Museum of the Earth in Warsaw (MZ), are studied herein. The abundant material has allowed for investigations of the intraspecific variation and revision of earlier determinations. As a result, 21 species belonging to 5 genera have been identified, described and illustrated, of which one is new [Clanculus (Clanculopsis) krachi sp. nov.] and one is left in open nomenclature. Granulifera O. Anistratenko, 2000 is considered a junior subjective synonym of Clanculopsis Monterosato, 1879; Granulifera pulla O. Anistratenko, 2000 is considered a junior subjective synonym of Monodonta tuberculata Eichwald, 1830; Gibbula sytovae Amitrov, 1961 is considered a junior subjective synonym of Trochus miocaenicus Mayer, 1853; Gibbula volhynica Friedberg, 1928 is considered a junior subjective synonym of Trochus novemcinctus von Buch, 1830; and Trochus buchii du Bois de Montpéreux, 1831 is suppressed in favour of the senior subjective synonym Trochus puschii Andrzejowski, 1830. The geographic distribution and stratigraphic ranges of the taxa are given. Six species are known only from the Polish-Ukrainian part of the Fore-Carpathian Basin. The protoconch features are systematically studied in the Trochidae and Calliostomatidae from this area for the first time.

The early Badenian interval in the Central Paratethys realm is characterized by a major marine transgression into the Pannonian and Carpathian Foredeep basins. In the western part of the Polish Carpathian Foredeep, Badenian sedimentation started generally with conglomerates (Dębowiec Formation) passing into a thick succession of claystones and mudstones with rare sandstone interbeds (Skawina Formation). Profiles containing a full sequence of lower Badenian strata are relatively rare, and are mainly known from boreholes. In this paper, we present new results on samples taken from such a borehole (Kaczyce K2/07) located near the town of Cieszyn. We focus on reconstructing the chronology of the lower Badenian marine sediments at the beginning of the transgression in the Carpathian Foredeep (lower Skawina Fm.) using radio-isotopic dating (40Ar/39Ar) of a volcanoclastic layer (tuff and tuffite) and biostratigraphy of calcareous nannoplankton and foraminifera.The weighted mean 40Ar/39Ar age for sanidine separates from the tuff provided an age of 14.27 ± 0.03 Ma. This age is consistent with the NN5 and MNN5a nannofossil zones determined in this study. Our foraminiferal assemblages show that the basal beds of the Skawina Formation up to the tuffites correspond to the Orbulina suturalis–Praeorbulina glomerosa Zone (according to Cicha et al., 1975) and cover the interval of the Lower Lagenidae Zone–lowermost Upper Lagenidae Zone (Grill, 1941). The petrographic data from the tuffite allow correlation of the tuffite from the Kaczyce K2/07 borehole to the level of the Chełmek Tuffite Bed (Alexandrowicz, 1997) providing a regional correlation horizon for future studies.

Zooxanthellate corals in the Badenian (Langhian to lower Serravallian) of western Ukraine occur in different lithofacies, but are most abundant in the upper Badenian coralgal reefs of the Ternopil Beds. The coral assemblage consists of five genera, with two predominant (Tarbellastraea and Porites) and three strongly subordinate (Favia, Heliastraea, Siderastrea). The present study is the first record of Heliastraea defrancei in the Fore-Carpathian Basin. The taxonomic composition of the corals indicates that their development occurred in conditions of some ecological stress, most probably connected with climate (location at the northern limit of coral distribution) and sedimentary environment (possible influx of terrigenous material). The coral assemblage shows similarities to numerous fossil reefs of Miocene age from the Paratethyan and Mediterranean realms.

The decapod fauna from the Badenian (middle Miocene) deposits of western Ukraine comprises in total 31 taxa: 20 species, 9 taxa left in open nomenclature, and 2 determined at family level. Thirteen of these taxa are reported for the first time from the territory of Ukraine. Among them are the first records of Trapezia glaessneri Müller, 1976 in the Fore-Carpathian Basin and Pachycheles sp. in Paratethys. One taxon (Petrolisthes sp. A) probably represents a new species. The occurrence of this significant decapod fauna is restricted almost exclusively to the Upper Badenian (i.e., early Serravallian) coralgal reefs of the Ternopil Beds. The taxonomic composition of the decapods indicates that the Late Badenian depositional environment was a shallow marine basin dominated by reefs that developed in warm-to-tropical waters of oceanic salinity. The decapod assemblage from the Ternopil Beds is similar in its taxonomic composition to numerous decapod faunules from fossil reefs of Eocene to Miocene age from the Mediterranean realm and of Miocene age from Paratethys. In contrast, decapod remains are very scarce in Badenian siliciclastic deposits (Mikolaiv Beds) and are represented by the most resistant skeletal elements, i.e., dactyli and fixed fingers. This scarcity was caused by the high-energy environment, with frequent episodes of redeposition, which disintegrated and abraded the decapod remains.

For the first time, articulated shells of Anomia ephippium Linnæus, 1758, the bivalve species widely distributed in the Egerian–Late Badenian (latest early Oligocene to late middle Miocene) in the Central Paratethys, are described and illustrated. The most astonishing fact is the presence of a heavily calcified byssus that anchored the animal to hard substrates, which is still preserved inside the byssal notch. The investigated material derives from the Badenian (middle Miocene) Niskowa Formation in the Nowy Sącz Basin, a small intramontane basin situated in the Polish Outer Carpathians. Apart from articulated shells and left valves, the collected material contains some dozen of calcified byssi fixed to rigid substrate, SEM images of which are presented. Examination of the A. ephippium specimens stored in the Polish Academy of Sciences, Museum of the Earth in Warsaw revealed other Paratethyan records of anomiid calcified byssi attached to other specimens of A. ephippium. Finally, the paper provides an overview of the previous studies on the representatives of the genus Anomia Linnæus, 1758 from the Central Paratethys and its specific assignment.

Pale brownish celestine-rich salt rocks were found near the Franciuszek Müller gallery, in the chambers of the 3rd level in the Wieliczka Salt Mine. The complex of rock salts subjected to exploration occurred within a large seam approximately 15 m thick. Detailed research revealed that the salt has the form of a block incorporated within the gray salts body and being similar to other blocks of green salts, well known in the upper part of the deposit. A characteristic petrographical feature of the pale brown rock salt owed to the presence of celestine (SrSO 4 ). That strontium mineral was re-examined, using X-ray powder data, and scanning microscope observations, with EDS analysis. The investigated rock salts exhibited a mineral association of halite (main component), anhydrite, celestine, calcite, gypsum, clay materials, iron compounds and a small amount of bitumen. Interrigenous sediments and the insoluble part of salt occurred higher content of strontium that in halite. Celestine crystals were observed in two forms: elongated platy crystals, forming fan-shaped aggregates and granular aggregates, strongly associated with anhydrite. On carbonate and sulphate strontium usually appearing as needle shaped aggregates of celestine. No barium minerals were observed. The development and paragenesis of celestine suggested a post-sedimentary origin of these rocks that ought to be connected with diagenetic processes. An important observation that confirmed that thesis was the transformation of fine crystalline anhydrite into platy crystals, recrystallization and primary accumulation of strontium, as a result of evaporation processes.

The genus Diodora Gray, 1821 is widely represented in the Middle Miocene of the Central Paratethys with specimens usually attributed to D. graeca (Linnaeus, 1758) or D. italic (Defrance, 1820), well-known recent species of the Atlantic / Mediterranean Basin. In samples from the Upper Badenian of Western Ukraine we found two clusters of Diodora specimens, showing a similarity with these species, but a review of shell diagnostic characters using a statistical approach has revealed their clear conchological separateness. The first species from Varovtsi and Horodok is attributed herein to D. nodosa (Eichwald, 1830), whereas the second species from Maksymivka is described as a new species, D. stalennuyi sp. nov. We consider that these molluscs inhabited the Polish-Ukrainian marginal part of the Late Badenian Basin. Detailed descriptions of the protoconch and teleoconch morphology of the taxa involved, including SEM images, are presented.

Występujące w basenie przedkarpackim badeńskie (środkowomioceńskie) gipsy odsłaniają się w licznych punktach na terenie Ukrainy. Jednym z nich są okolice miejscowości Szczerzec (ukr. Щирець), 25 km na SSW od Lwowa. Jest to potencjalny obszar stratotypowy badeńskiej formacji gipsowej, na Ukrainie znanej jako suita tiraska, a także wyjątkowy teren ze względu na znajdujące się tu odsłonięcie anhydrytów w kamieniołomie Pisky (ukr. Піски), gdzie w strefie wietrzenia powstają unikatowe formy jaskiń zwane jaskiniami z hydratacji lub jaskiniami z pęcznienia. Na obszarze Ukrainy dane kartograficzne zarówno te dotyczące geologii, jak i morfologii są niekompletne, a obecnie dostępne materiały archiwalne wymagają uaktualnienia. W pracy opisano sposób w jaki opracowano nową, uaktualnioną wersję mapy geologicznej okolic Szczerca w przestrzeni trójwymiarowej (3D). W tym celu wykorzystano istniejące mapy topograficzne oraz archiwalne mapy geologiczne, które poddano procesowi wektoryzacji. Większość prac wykonano w programie ArcGIS 10.1. Na przykładach zademonstrowano użyteczność mapy 3D do ilościowej analizy wybranych elementów rzeźby oraz budowy geologicznej.

The Badenian (Middle Miocene) gypsum occurring in the Carpathian Foredeep basin is exposed in a great number of locations in Ukraine, including the environs of Shchyrets, 25 km SSW of Lviv. In this area the potential stratotype of the Badenian gypsum is exposed, known as the Tyras Suite in Ukraine. The area is also of great scientific value because of the anhydrite rocks exposed at the Pisky quarry (near Shchyrets). Recently, unique forms of caves known as hydration caves or swelling caves have been formed in the weathering zone of this anhydrite. In the territory of Ukraine, both morfological and geological cartographic data are incomplete. Nowadays, available archival documents need updating. This paper describes the way of preparation of a new, updated version of the geological map of Shchyrets environs in three-dimensional space (3D). The topographic and archival geological maps were used, which were subjected to process of vectorization. The main part of the work was done in ArcGIS 10.1. Usefulness of the constructred 3D map for quantitative geomorphological and geological analysis is shown on selected examples.

Multiproxy sedimentological, gamma-spectrometric, foraminiferal, calcareous nannoplankton, and otolith data were used for the reconstruction of the Badenian (Middle Miocene) history of the Moravian part of the Carpathian Foredeep. The study material originated from the new borehole LOM-1, which drilled >20 metres of monotonous clayey siltstones with exceptionally rich and well-preserved microfossil assemblages. Distal parts of the Carpathian Foredeep (a forebulge depozone) are exposed in this succession. Generally, a quiet environment of outer shelf to upper bathyal of monotonous clayey silts was interpreted, which is typical for the proximal parts of a peripheral foreland basin. The section studied can be subdivided into six intervals, confirming the cyclical character of Middle Miocene sedimentation in the Central Paratethys. Interannual oscillations of nutrient content, temperature and/or salinity are interpreted based on the oscillations of geochemical as well as palaeobiological data. The turnover connected with the initiation of the Middle Miocene Climatic Transition is recorded above the LO (last occurrence) of Helicosphaera waltrans in agreement with previous observations in the Carpathian Foredeep. The changes include cooling, a decrease in nutrients, a probable increase of the salinity of surface water, and increase of seasonality. Seasonality was manifested by an alternation of mixed and stratified water columns with a seasonal input of nutrients. Concerning nutrients, sources of seasonal riverine input or seasonal upwelling are both possible.

Skład i zmiany zespołów otwornic pochodzących z najwyższej części utworów podewaporatowych w otworze wiertniczym Busko (Młyny) PIG-1 (głęb. 188–192 m), zlokalizowanym w północnej części zbiornika przedkarpackiego (Paratetyda Środkowa), wskazują, że zbiornik, w którym powstawały osady margliste, był słabo wentylowany, z dużym deficytem tlenowym w wodach przydennych oraz ze środowiskiem eutroficznym w wodach powierzchniowych. Zbiornik ten, o głębokości 50–70 m, wypełniały wody chłodne o zasoleniu typowym dla zbiornika morskiego. Obserwowane w najwyższej części profilu prawie całkowite wyeliminowanie otwornic Uvigerina i zajęcie na krótko zwolnionej niszy przez Fursenkoina acuta (zespół D4c) oraz zdominowanie składu najmłodszego zespołu (D4d) przez tolerującą podwyższone zasolenie Bulimina elongata może jednak wskazywać na znaczne podwyższenie zasolenia w trakcie depozycji najwyższej części utworów poprzedzających depozycję gipsów. Profil gipsów badeńskich w badanym otworze wiertniczym w porównaniu z bardziej brzeżną strefą platformy gipsowej cechuje się redukcją dolnej, autochtonicznej części gipsów oraz specyficznym wykształceniem najniższej jednostki gipsów. W matriksie ilastym występują tam gruzły gipsu bardzo przypominające małe, chaotycznie ułożone blokowe zrosty krystaliczne, określane jako facja szkieletowa gipsów szklicowych, związana w niecce Nidy oraz na Morawach z obniżeniami dna. Wykształcenie profilu gipsów wskazuje na głębsze środowisko sedymentacji niż to stwierdzono w rejonie niecki Nidy.

Composition and changes in foraminiferal assemblages recorded in the uppermost part of the sub-evaporite deposits of the Busko (Młyny) PIG-1 borehole (depth 188–192 m) in the northernmost part of the Fore-Carpathian Basin (Central Paratethys) indicate that the basin, in which marly deposits have originated, was poorly ventilated with a great oxygen deficit in the bottom waters, and was characterised by mainly eutrophic conditions in surface waters. The basin was 50–70 m deep. The waters were cool and of normal seawater salinity, although the recorded (in the uppermost part of the section) almost complete disappearance of Uvigerina foraminifers, occupation (for a short time) of the vacant niche by Fursenkoina acuta (assemblage D4c), and the dominance of Bulimina elongata (tolerant to increased salinity) in the youngest assemblage (D4d) may indicate a considerable increase of seawater salinity during the deposition of the uppermost part of the sub-evaporite strata. The gypsum section is characterised, when compared to the more marginal gypsum sections of the Nida Trough, by a reduction of the lower, autochthonous part of the gypsum section and a specific development of the lowermost gypsum unit. It contains gypsum nodules resembling small, chaotically arranged gypsum intergrowths in the clayey matrix. Such facies is regarded as the skeletal facies of the giant gypsum intergrowth facies of the Nida Trough and Moravia, and is related to depositional lows at the beginning of the gypsum deposition. The gypsum sequence in this borehole indicates a deeper sedimentary environment than inferred for the Nida Trough.

Trzeci zespół (Z.s.III), ze względu na zły stan zachowania mikrofauny, zaliczono ogólnie do sarmatu. Zastępujące się obocznie planktoniczne i bentoniczne zespoły otwornicowe potwierdzają duże zróżnicowanie facjalne osadów, które powstały w późnym badenie i we wczesnym sarmacie w brzeżnej części zapadliska przedkarpackiego.

Micropaleontological study of Miocene deposits from the Busko (Młyny) PIG-1 and Kazimierza Wielka (Donosy) PIG-1 boreholes, located in the northern part of the Carpathian Foredeep, has allowed taxonomic and biostratigraphic characteristics of foraminiferal assemblages. The samples were taken from clay and clay-marly interbeds in sub-evaporitic, evaporitic and supra-evaporitc complexes. In the Busko (Młyny) PIG-1 borehole, five foraminiferal assemblages have been defined (Z.b.I–Z.s.V), corresponding with the following foraminiferal zones: Orbulina suturalis/ Praeorbulina – Z.b.I (Moravian substage of the Early Badenian), Neobulimina longa – Z.b.II; Velapertina indigena – Z.b.III, Hanzawaia crassiseptata – Z.b.IV (Kosovian substage of the Late Badenian) and Anomalinoides dividens – Z.b.V (Volhynian substage of the Early Sarmatian). In the Kazimierza Wielka (Donosy) PIG-1 borehole, two foraminiferal assemblages have been identified (Z.b.I and Z.s.II), correlated with following foraminiferal zones Velapertina indigena – Z.b.I (Kosovian substage of the Late Badenian) and Varidentella sarmatica – Z.s.II (Volhynian substage of the Early Sarmatian). The third assemblage (Z.s.III), because of poor preservation of foraminifers has been attributed to the Sarmatian stage in general. Lateral replacement of planktonic and benthonic foraminiferal assemblages confirms a significant facies variability of the Late Badenian deposits that accumulated in the northern margin of marine basin in the Carpathian Foredeep.

Ten new determinations of the stable sulphur isotope content of anhydrite from Badenian rock salt in the Hrynivka 525 borehole (Ukrainian Carpathian Foredeep) show that δ34S values in anhydrite range from +20.2 to +22.7‰ and the average value of δ34S is +21.4 ± 0.3‰. Those values are similar to those of the Neogene marine sulphates. Comparison to other geochemical data (chemical composition of the brine contained in fluid inclusions and the bromine content in halite) suggests that the Badenian Carpathian Foredeep evaporite basin was supplied predominately by seawater solutes where, at different stages of salt accumulation, the influence of continental waters with lighter isotopic compositions of dissolved sulphate was important. The isotopic composition of sulphur (δ 34S) of Badenian seawater, calculated on the basis of sixty analyses of anhydrite related to halite of the Carpathian Region, is approximately +20.3‰, this value being similar to the sulphur isotopic composition of present-day seawater. The δ 34S value for Badenian seawater may have been slightly higher if we consider potential changes of the brine composition of salt-bearing basins caused by inflow of continental waters enriched in light 32S isotopes.

The Zoloushka Cave belongs to a group of the largest gypsum caves in Western Ukraine (Bukovina region), developed in the middle Miocene (upper Badenian) evaporite series (Tyras Formation) on the SW periphery of the East European Platform. It is developed in the lower part of the evaporite series composed of gypsum, which is covered by a carbonate layer (Ratyn Limestone). The uneven upper surface of the gypsum at the contact with the limestone, the frequent occurrence of palaeokarst forms, and the presence of karstified fissures filled with allochthonous material indicate a sedimentation break between the gypsum and the overlying limestone. To support this thesis and to add new data on the age and palaeoenvironmental conditions of palaeokarst formation in the Bukovina region, palynological studies were carried out on material from the Zoloushka Cave. Palynofacies, sporomorphs and dinoflagellate cysts were studied. In total, over 70 sporomorph taxa and over 25 dinoflagellate cyst taxa have been identified in four samples collected from the filling of the palaeokarstic forms in the cave. The results of the analysis of sporomorphs and dinoflagellate cysts point to the formation of the palaeokarst during the sedimentation break that took place at the end of the late Badenian evaporitic cycle in the Western Ukraine region. The subsequent marine transgression led to the filling of the karst forms in gypsum with chemogenic carbonate material, precipitated from marine water (draperies) and with fine-grained, clastic material (pockets and fissures).

Globorotaliids of the Skawina Formation (Badenian) come from deposits representing CPN 7 (Orbulina suturalis Zone) and CPN 8 sub-evaporite Wielician (Globigerina druryi–G. decoraperta Zone alias Uvigerina costai Zone) age. There are two taxonomic groups of globorotaliids in the studied material: globoconellids (Globoconella bykovae and G. minoritesta) and jenkinsellids (Jenkinsella mayeri and J. transsylvanica). There are five stratigraphically-rank intervals of these foraminifers prior to the Middle Badenian salinity crisis in Central Paratethys. The investigated Badenian begins with G. bykovae–J. mayeri association followed by the first occurence (FO) of J. transsylvanica. The closing member of the CPN 7 biozone is the G. bykovae–J. transsylvanica assemblage. The jenkinsellids disappear during CPN 7: J. mayeri first and J. transsylvanica after. Since the base of CPN 8 in situ jenkinsellids have not been noted in the Badenian deposits. The CPN 8 begins with a stratigraphic interval barren of globorotaliids (biozone IIC in the Polish Paratethys). It is followed by episodic appearances of globoconellids (G. bykovae and G. minoritesta) in the sub-evaporite Wielician (IID biozone in Poland). G. minoritesta has been found in only one case so far. The globorotaliid stratigraphic units are distinct and well-correlated with changes in climate and the circulation of water masses in Paratethys. This study provides additional data on Mi3 in Paratethys. It documents a cryptic cooling event in the late Orbulina suturalis Zone (mid CPN 7) located at the late IIA–B assemblage (alias upper lagenide zone) in regional biostratigraphic scale. The event is recorded by J. transsylvanica Acme, matching with circa 1‰VPDB δ18O positive excursion. The event must have resulted in a considerable sea level drop – a trigger of the Moravian ecosystem demolition in the Paratethys environment.

Foraminifers occurring in marls underlying the Middle Miocene Badenian gypsum in the northern Polish Carpathian Foredeep in one borehole section [Młyny (Busko) PIG 1] and in two dewatering pits in operating quarries (Leszcze and Borków) contain well-preserved foraminifers. Sixty-seven species of benthic and twenty-one species of planktonic foraminifers are recorded in the 12-m-thick section of the Młyny borehole. Benthic assemblages are characterized by the dominance of Bulimina and Uvigerina while planktonic assemblages are composed mainly by warm-water orbulinids and Globigerinoides spp. in the lower part of the Młyny section and by temperate-cold water Globigerina spp. in the upper part of the Młyny section as well as the Leszcze and Borków sections. The taxonomic composition of foraminiferal assemblages makes it possible to distinguish two foraminiferal zones in the Młyny borehole: the Orbulina suturalis and Uvigerina costai zones, and only the latter zone is accessible at Leszcze and Borków. The benthic foraminiferal successions in the studied interval suggest oxygenation and productivity changes in the Carpathian Foredeep Basin prior to the Badenian salinity crisis. Four intervals of lowered oxygenation and/or elevated organic flux to the sea-floor are recognized; the intervals in which foraminiferal assemblages suggest marine environments with lowered oxygenation in bottom waters alternate between the intervals where stress markers form less than 50% of the benthic foraminiferal assemblages. Benthic assemblages are moderately to highly diversified, and species have more equal frequencies. The upsection decrease in the proportion of planktonic foraminifers reflects the shallowing of the basin accompanied by a decrease in the temperature gradient between the upper (warmer) and deeper (colder) water beds. The average palaeotemperature of water based on d18O of Uvigerina and Globigerina decreased by ca. 2 and ca. 6°C, respectively (from 9.9 and 17.4°C in the Orbulina suturalis Zone to 7.9 and 11.5°C in the Uvigerina costai Zone, respectively). Below the gypsum, the d18O values of both benthic and planktonic foraminifers show quite large variations possibly due to the salinity increase. Coeval domination of benthic foraminiferal assemblages by Bulimina suggests increased surface water productivity and an increased organic flux to the sea-floor prior to the onset of evaporite deposition and/or salinity increase.

The Mykolaiv Sands are a huge lithosome of Middle Miocene (Badenian) age, accommodated within the Fore-Carpathian Basin in the Western Ukraine. Typically developed in the area of Opole Minor, it spreads across adjacent regions of Opole to cover an area of about 1300 km2. The varied sedimentary structures and ubiquitous burrows, indicate their development as a stack of sand shoals or related bodies, up to a few tens of metres thick, some of which temporarily reached sea level. Amidst the shoals, storm scours intermittently formed channel-like infills, some with residual lags at the base. The reversed density stratification and/or an increasing gravity gradient involved mass movements, some of which may have been triggered by seismic shocks focused at the shore or the adjacent hinterland of Podolia and Volhynia. Special attention is paid to the diverse fossils, all taphonomically filtered (aragonite shells and chitinous carapaces being lost), but which locally are mass-aggregated. They typify particular sand sets/bodies, to form allochthonous assemblages, some members of which (the cirripedes Scalpellum and Creusia, the shark Hemipristis, the ray Myliobatis) are newly recognized in the Ukrainian part of the Fore-Carpathian Basin. The others enrich considerably the faunal content of the Middle Miocene (Badenian) Paratethyan basins, either in terms of taxonomic diversity, or the eco-taphonomy of selected taxa (the starfish Astropecten, diverse echinoids). The whole faunal content of the Mykolaiv Sands may owe its profuse development to the global Middle Miocene Climatic Optimum of early Badenian age.

This is the first Paratethyan record of a minute scallop species Parvamussium fenestratum (Forbes, 1844). The species was found in Middle Miocene (Upper Badenian) clayey deposits in the Surzha borehole, the Ukrainian Carpathian Foredeep Basin. Examination of other Parvamussium specimens stored in the Museum of the Earth in Warsaw and in the Hungarian Natural History Museum in Budapest revealed further Paratethyan records of Parvamussium fenestratum. These specimens, previously referred to Parvamussium felsineum (Foresti, 1893), were identified in the Middle Miocene faunas of Poland (Monastyrz and Długi Goraj, Roztocze Hills) and Hungary (Makkoshotyka, Tokaj Mts.). In the Mediterranean Neogene this extremely rare species has been reported from the Lower Miocene (uppermost Burdigalian) of Italy and from the Lower Pliocene (Zanclean) of Spain. Research on the Oligocene-Miocene succession in the Paratethys has shown representatives of Parvamussium Sacco, 1897 to be moderately abundant in clayey facies in different basins and the genus is regarded as biostratigraphically important. Data on the distribution of other Paratethyan and Neogene Mediterranean Parvamussium species viz., Parvamussium bronni (Mayer, 1861), P. duodecimlamellatum (Bronn, 1831), P. felsineum (Foresti, 1893) and P. miopliocenicum (Ruggieri, 1949) are reported. Finally, palaeobiological and palaeobiogeographical characteristics on the genus Parvamussium Sacco, 1897 the Early Cretaceous to Recent time span are described.
