Opis:
Remains of decapod crustaceans of the family Alpheidae Rafinesque, 1815 and bony fish of the family Gobiidae Bonaparte, 1832 co-occur at a number of localities in the Korytnica Basin (Holy Cross Mountains) and in a newly exposed section along a stream near Niskowa (Outer Carpathians), both in southern Poland. These remains (alpheid major right-sided cheliped tips and gobiid otoliths) are interpreted as documenting a commensal partnership that existed in the shallowest zones of the middle Miocene Fore-Carpathian Basin in southern Poland under environmental conditions that must have been comparable to those of the present-day tropical/ subtropical Indo-West Pacific and Caribbean.

Opis:
A new species of heterobranch gastropods, the hammerhead Chelidonura radwanskii sp. nov., found in the socalled Pleurotoma-clays of middle Miocene (Langhian) age in the environs of Korytnica, southern Holy Cross Mountains, Poland, is described. It is the first fossil representative of Chelidonura A. Adams, 1850. This tiny gastropod is named in honour of the late Professor Andrzej Radwański.

Opis:
A nearly complete skull, a partial left scapula, five lumbar vertebrae, and some fragments of ribs of a medium−sized kentriodontid dolphin (Cetacea, Odontoceti) discovered in the middle Miocene of Setúbal Peninsula, Lower Tagus Basin, Portugal, are herein assigned to a new genus and species, Tagicetus joneti. Within the grade−level family Kentriodontidae, the new taxon is referred to the specifically and ecologically diversified subfamily Kentriodontinae, essentially defined by a well−developed posterolateral projection of the nasal. The elongated rostrum, the constriction of the asymmetric premaxillae at the base of the rostrum, the anteriorly elongated palatines, and the elevated vertex of T. joneti suggest closer affinities with the larger, more derived Macrokentriodon morani, from the middle Miocene of Maryland (USA). Among other features, T. joneti differs from the latter in having more numerous maxillary teeth and shorter zygomatic processes of the squamosals. Besides providing additional indications about the evolutionary trends within the Kentriodontinae, this occurrence constitutes the first record of the subfamily from the east coast of the North Atlantic based on a nearly complete skull. Considering their morphological diversity and wide geographic range, the Kentriodontinae may have constituted one of the dominant groups of Miocene oceanic dolphins.

Opis:
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.

Opis:
A rich assemblage of microfossils, including foraminifera, ostracodes and bolboforms (calcareous phytoplankton) have been found in the supra-evaporitic deposits of the Pecten Beds (Upper Badenian) and Krakowiec Clays (Sarmatian) of Middle-Miocene age, which occur in the Jamnica S-119 borehole near Tarnobrzeg, in the central part of the Carpathian Foredeep. Environmental conditions have been deduced from these microfossils. Comparison with other parts of the Carpathian Foredeep shows that microfauna distribution depended on location within the sedimentary basin and on hydrological conditions. Poorly-diversified and specific microfossils were associated with evaporites and overlying sediments (particularly within the lower Pecten Beds and Krakowiec Clays), indicating poorly-oxygenated near-bottom waters. Possibly, "Upper-Badenian" and "Sarmatian" biofacies had already differentiated by the end of the Badenian. Distribution of the Upper Badenian microfauna and bolboforms in the Polish part of the Carpathian Foredeep and beyond shows that there was faunal exchange between the eastern and western parts of the Polish section of the Carpathian Foredeep, and indicates connection between the Central Paratethys and Mediterranean basin areas.

Opis:
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.

Opis:
Echinoderms from the Badenian (Middle Miocene) of the Fore-Carpathian Basin of western Ukraine are facies restricted. The Mykolaiv Beds, stratigraphically older, yielded the starfish Astropecten forbesi (complete skeletons), two genera of sand dollars (Parascutella, Parmulechinus), and numerous other echinoids of the genera Psammechinus , Echinocyamus, Spatangus, Hemipatagus, Echinocardium, Clypeaster, Echinolampas, and Conolampas. The stratigraphically younger, calcareous Ternopil Beds yielded Eucidaris (complete coronae, isolated spines), Arbacina , Brissus, and Rhabdobrissus. Sixteen species of echinoids are distinguished and/or commented. A new brissid, Rhabdobrissus tarnopolensis sp. nov., is established. A mass occurrence of some species (Psammechinus dubius and Hemipatagus ocellatus) contrasts with that of mass aggregations (sand dollars and Echinocardium leopolitanum) by dynamic events in selected layers of proximal tempestites. Of special note is the occurrence of very small specimens, interpreted as juveniles (‘babies’) having been swept out of their restricted biotopes (‘nurseries’). Some species hitherto regarded as of Early Miocene age, and the problem of their persistence beyond the Fore-Carpathian Basin and/or migration into that basin during the Middle Miocene transgression are discussed.

Celem opracowania jest rozpoziomowanie utworów miocenu środkowego w profilu Trojanowice 2 na podstawie zespołów nanoplanktonu wapiennego. W zespołach nanoplanktonu dominują gatunki długowieczne należące do Coccolithaceae i Prinsiaceae. Mniej licznie występują: Helicosphaeraceae, Sphenolithaceae i Discoasteraceae. Na podstawie oznaczonych w próbkach gatunków: Sphenolithus heteromorphus, S. abies, Helicosphaera walbersdorfensis, Discoaster exilis, Calcidiscus macintyrei, Cyclicargolithus floridanus, Reticulofenestra pseudoumbilica, Umbilicosphaera rotula oraz niewielkich rozmiarów form należących do rodzajów Reticulofenestra i Helicosphaera badane utwory odniesiono do poziomów kokolitowych NN5 i NN6 w standardowej zonacji Martiniego.
The aim of the study was to establish the zonation of Middle Miocene sediments in the Trojanowice 2 borehole, based on calcareous nannoplankton investigations. Long-ranging families are dominant, representing Coccolithaceae (Coccolithus pelagicus) and Prinsiaceae (small reticulofenestrids, R. pseudoumbilica). Helicosphaeraceae (small helicosphaerids, H. kamptneri), Sphenolithaceae and Discoasteraceae, which are important for stratigraphic conclusions, occur less frequently. Based on the co-occurrence of Sphenolithus heteromorphus, S. abies, Helicosphaera walbersdorfensis, Discoaster exilis, Calcidiscus macintyrei, Cyclicargolithus floridanus, Reticulofenestra pseudoumbilica, Umbilicosphaera rotula and small forms belonging to the Reticulofenestra and Helicosphaera species, the sediments are included into NN5 and NN6 calcareous nannoplankton zones sensu Martini.

Opis:
The foraminiferal contents of the lower–middle Miocene succession exposed in three sections in north Nur Abad on the northwestern side of the High Zagros Thrust Belt were studied. Assemblages of larger foraminifera from these sections can be referred to Zone SBZ 25 (and the Miogypsina globulus and Miogypsina intermedia subzones), which correlates with the Burdigalian Stage. For the first time, planktonic foraminifera documented from the Nur Abad area document Langhian deposits in the High Zagros, the upper 20 metres of the upper Sayl Cheshmeh section being characterised by the occurrence of planktonic foraminifera such as Globigerina concinna (Reuss), Globigerina diplostoma (Reuss), Globigerinoides obliquus (Bolli), Orbulina bilobata (d’Orbigny) and O.universa (d’Orbigny). This association characterises the Orbulina suturalis Interval Zone.

Opis:
Limestone erratics in the Early Miocene glacio−marine Cape Melville Formation of King George Island, West Antarctica, have yielded Early and Middle Cambrian small skeletal fossils (SSF) accompanied by calcified cyanobacteria, archaeocyath and spiculate sponges, trilobites and echinoderms. The SSF assemblage comprises disarticulated sclerites of chancelloriids, halkieriids, tommotiids, lapworthellids, palaeoscolecids, hyolithelminths, lingulate brachiopods, helcionelloid molluscs, hyoliths, and bradoriids. All 24 described species are common to Antarctica and Australia. Most are recorded here from Antarctica for the first time, including Shetlandia multiplicata gen. et sp. nov. and two new species Byronia? bifida and Hadimopanella staurata. The lithological and fossil contents of the boulders are almost identical with autochthonous assemblages from the Shackleton Limestone in the Argentina Range and Transantarctic Mountains. Cambrian outcrops around the Weddell Sea are a plausible source of the erratics. The fauna is closely similar to that from the uppermost Botomian Wilkawillina Limestone in the Flinders Ranges and Parara Limestone on Yorke Peninsula, and Toyonian Wirrealpa and Aroona Creek Limestones in the Flinders Ranges, as well as the Ramsay Limestone on Yorke Peninsula, all in the Arrowie and Stansbury Basins of South Australia. These very similar faunal and facies successions for Antarctica and Australia strongly support their common biotic and sedimentary evolution on the same margin of a greater Gondwana supercontinent throughout the Early Cambrian.

Opis:
The Upper Badenian and Sarmatian sandstones recognized from boreholes in southeastern Poland and western Ukraine are very fine to medium-grained subarkosic and sublithic arenites and wackes. The deposits underwent diagenesis well below 100°C, and their evolutionary pathways of diagenetic and related reservoir properties represent eo- and mesodiagenesis. Eodiagenesis here comprised mechanical compaction, development of chlorite, microcrystalline calcite, pyrite, siderite, kaolinite and quartz, and dissolution of feldspar and mica grains. Mesodiagenesis included quartz and K-feldspar overgrowths, albitisation, crystallisation of dolomite and ankerite and coarsely crystalline calcite, dissolution of feldspar grains and carbonate cement, and illite growth. The isotopic data of δ18OVPDB of carbonate cements suggest their crystallisation from porewater which is a mixture of marine and meteoric waters. The δ13CVPDB values suggest derivation of carbon from microbial methanogenesis of organic matter. The 87Sr/86Sr values in coarsely crystalline calcite are higher than those of Badenian seawater. The radiogenic strontium may have been supplied during diagenesis by meteoric waters draining the continental area. The Middle Miocene sandstones show better filtration abilities (good and very good) in the western part of the study area (Poland) than in the east. Primary intergranular porosity is more frequent than secondary intragranular and intercrystalline porosities.The primary porosity was diminished due to compaction and cementation from west to east. Some increase in porosity was caused by dissolution of detrital grains and by decay of soft parts of organisms.

Opis:
The paper deals with sub-evaporite Badenian deposits (Middle Miocene, Paratethys) that display a sudden appearance of globorotaliid taxa showing preferences in the taxonomic set and coiling direction. An interval of sinistrally coiled Jenkinsella mayeri with proportionally coiled Globoconella bykovae is at the bottom of the studied sequence. It is followed by an interval of proportionally coiled Jenkinsella transsylvanica. Proportionally coiled Globoconella bykovae with a small number of proportionally coiled Jenkinsella transsylvanica are at the top of the Moravian (CPN 7) substage (Orbulina suturalis alias Lagenidae Zone). The sub-evaporite part of the Wielician (CPN 8) substage (Uvigerina costai alias Spiroplectammina Zone) began with a globorotaliid-barren interval (IIC biozone). It is followed by biozone IID displaying three globorotallid peaks amongst globorotallid-barren deposits. Only globoconellas are present in all these three events. Proportionally coiled Globoconella bykovae appeared first. It is followed by proportionally coiled Globoconella minoritesta and sinistrally coiled Globoconella bykovae at the end of the biozone IID. Coiling preferences of globorotaliids have been compared to changes in the hydrographic regime unfolding during the CPN 7 and CPN 8 in the studied area of the Paratethys. The study discovers that the coiling of globorotaliids responded selectively to the hydrographic changes. Globoconella bykovae is highly opportunistic and can tolerate considerable temperature changes. Specimens of this taxon persist to coil proportionally during the sub-evaporite Badenian, except for the shift to sinistral coiling just prior to the Wielician evaporites. Sinistrally coiled Jenkinsella mayeri is the most sensitive to hydrographic changes. This taxon retreated at the onset of the temperature drop during the mid-Moravian cryptic cooling. This cooling is marked by the new jenkinsellid occurrence – proportionally coiled Jenkinsella transsylvanica. Proportionally coiled Globoconella minoritesta is present in the middle of the IID globorotaliid peaks. The globorotaliid coiling data, presented in this paper, has been calibrated to the global stratigraphy. The integrated data (foraminifera, nannofossils, oxygen and carbon stable isotopes, radiometric measurements) supports the view that the CPN 7/CPN 8 boundary is coeval to the Langhian/Serravalian one. In the Polish part of the Carpathian Foredeep, the boundary runs within the Skawina Formation.

Opis:
Within the Carpathian Foredeep, open marine basin evolved into restricted evaporitic basin during the Badenian (Serravallian), and along the Carpathian front chloride sub-basins developed. The studies of foraminifera and calcareous nannoplankton were conducted to obtain new biostratigraphic data which could constrain the age and correlation of the salt deposits between Wieliczka-Bochnia in Poland, and Kalush in the Ukraine. These studies proved that chloride deposits (in the Ukrainian territory also potassium salts) originated generally during the same period corresponding to the Late Badenian NN6 zone and undivided NN6-NN7 zone. The uppermost part of sub-evaporitic beds belongs to the boundary between the NN5 and NN6 zones, although locally (Bochnia Salt Mine) only the NN6 zone was found. This suggests that the lower boundary of salt deposits can be diachronous. Deposits overlying the salt (Chodenice and lowermost part of Grabowiec beds - Bogucice Sands) represent the Late Badenian NN6/NN7 zone. The similarity in age between the folded Middle Miocene strata in Poland (Zgłobice Unit) and the Ukraine (Sambir Unit) implies that they were folded during the same time and that they can represent one tectonic unit, develo ped in front of the advancing Carpathian orogen.

Opis:
The aim of this study is to compare the assemblages of foraminifera and calcareous nannoplankton from the Middle Miocene sediments from SE Poland and western Ukraine. Detailed investigations revealed a high degree of similarity of foraminiferal assemblages of the Pecten/Spirialis beds of Poland and the Kosiv Formation of Ukraine. Assemblages from both areas are characterized by numerous arenaceous species of foraminifera (Hyperammina granulosa, Ammodiscus miocenicus, Haplophragmoides indentatus, H. laminatus), radiolarians, pteropods and index planktic species Velapertina indigena. High degrees of similarity also display assemblages from the Krakowiec beds (Poland) and the Dashava Formation (Ukraine). The lower parts of both subdivisions are characterized by the presence of Anomalinoides dividens. Saccammina sarmatica, Bolivina sarmatica, Brizalina nisporenica, and Porosononion granosum occur in the upper parts. Chloropycean Halicoryne morelleti is a characteristic element of the assemblages. The calcareous nannoplankton assemblages contain almost identical species. The deposits lying above the evaporites (which belong to the NN6 zone) are included into the NN6, undivided NN6-NN7, and NN7 zones. The gradual impoverishment of the species of the upper part of NN6 and the lower part of NN7 zones is observed. The assemblages of the Krakowiec beds and the upper part of the Kosiv and Dashava formations are of low species diversity and are mainly restricted to a few species with high abundance. The assemblage is composed of placoliths (Coccolithus and Reticulofenestra species), high number of the reworked nannofossils and damaged elements.

Opis:
Previously, it was believed that there was a dramatic turn−over in the fauna of beavers (Rodentia, Castoridae) from the Barstovian to the Clarendonian from Nebraska. Stratigraphically controlled collections of fossil castorids from the Valentine Formation, which cross this boundary, now indicate that a complete change in the castorid fauna did not occur, but instead a more gradual change and replacement of earlier taxa with more advanced taxa occurred. The range of Eucastor tortus and Monosaulax skinneri is extended from late Barstovian into the latest Barstovian Devil’s Gulch Member and the range of the otherwise Clarendonian species of Prodipoides is extended downward into the late Barstovian Crookston Bridge Member. The skulls of Monosaulax skinneri and Eucastor valentinensis are described in detail for the first time. The cranial morphology of M. skinneri is primitive for Castoroidini and that of E. valentinensis is specialized for tooth−digging behavior as in the Nothodipoidini. A new genus, Temperocastor, is proposed for E. valentinensis based on its primitive morphology of the cheek teeth and derived cranial morphology. Temperocastor represents the most primitive nothodipoidine.
