The Middle Miocene (Upper Badenian) coralline algal reefs of Western Ukraine contain caverns (up to 1 m across) and fissures that are filled by Sarmatian deposits: marly clays, clayey carbonate sand and bioclastic, bryozoan-rich sand. These deposits often contain abundant and very well preserved calcareous benthic foraminifera; agglutinated forms have not been recorded. Foraminiferal tests quite commonly show morphological abnormalities, e.g. twin forms or tests with irregularities in size or shape in last chambers. Each of the three analysed samples is characterized by a different foraminiferal assemblage: Elphidium aculeatum assemblage, Hauerinidae assemblage and Lobatula lobatula assemblage. These assemblages are characteristic for a shallow marine environment. Low taxonomic diversity and high dominance or monospecific foraminiferal assemblages indicate generally a restricted marine environment. It seems that the increasing salinity and very high-energy environment were the most ...

The paper deals with Middle Miocene (Badenian) bivalves from the limestones and marls of the Wojcza-Pinczow Range (southern slopes of the Holy Cross Mountains, Central Poland). Totally, 80 bivalve species are recorded, and the taxonomic structure of their assemblage is described. The Neogene European interprovince connections are indicated and the stratigraphic usefulness of pectinids is discussed. The systematic account includes the paleontological descriptions of 23 species, two of them, viz. Chlamys (Aequipecten) angelonii (de STEFANI & PANTANELLI), and Cyathodonta eggenburgensis (SCHAFFER), being for the first time reported from the Polish Miocene.

For the first time, articulated shells of Anomia ephippium Linnaeus, 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 .

THE SEDIMENTOLOGICAL-PALAEONTOLOGICAL STUDY OF THE LOWER SARMATIAN BARRIER DEPOSITS NEAR CHMIELNIK (SOUTHERN BORDER OF HOLY CROSS MTS) Summary The sedimentological investigations of 3 outcrops of "detrital Sarmatian" deposits near Chmielnik gave new data about their age and origin. The two complexes were distinguished, the older one (I) reperesented the seaward slope facies of spit, separating the Korytnica-Chmielnik bay from open sea in Lower Sarmatian time. The younger complex (II) was composed of high energy deposits of shoals and inlets within barrier, in which this spit has transformed during sea regression. The mollusc assemblage characteristics from complex I shows they are similar to primary biocenosis and could be regarded as "fossil community" sensu Fragerstrom or "death assemblage" (Model I) sensu Johnson. Bivalve studies of the association Ervilia podolica-Loripes dujardini-Pirenella picta mitralis have shown that complex I from Śladkow Maly...

The paper deals with the Paratethyan bivalve fauna recorded in Middle Miocene marine shallow-water sandy facies. Of the 429 recognized species, 343 occur in the Lower Badenian, 71 in the Chokrakian, 316 in the Upper Badenian, and 97 in the Konkian. Bivalve faunas are analyzed in order to determine the degree of similarity of contemporaneous assemblages from the Central and Eastern Paratethys, as well from Mediterranean and Atlantic bioprovinces. The study of Lower Badenian and Chokrakian bivalve faunas (isochronous with the Langhian fauna of the Mediterranean) reveals that the Eastern Paratethys was cut off intermittently from communication with the Central Paratethys. Biogeographic affinities and the geographic pattern of Chokrakian bivalve assemblages indicates that the south-eastern part of the Eastern Paratethys was connected with the world ocean by a passage towards the East Mediterranean named the Middle Araks Straight. The species composition of Lower Badenian bivalve assembl...

The unique Middle Miocene reef belt formed within the Paratethyan realm constitutes at present the Medobory Hills in western Ukraine and northernmost Moldova. Not only is the size of this structure (almost 300 km long) quite unusual, but also the development of peculiar facies and their spatial distribution. Two distinct reef generations appear in Medobory (Late Badenian and Early Sarmatian), both separated by a sharp erosional boundary. Two Upper Badenian calcareous lithofacies dominate – organodetrital and biohermal (with coralline-algae as main framework builders accompanied by a rich invertebrate assemblage). The Lower Sarmatian strata, although megascopically very similar to Upper Badenian ones, differ drastically when studied closely. The main reef components here are serpulids and microbialites, usually with ubiquitous, but taxonomically highly impoverished fauna. Differences in lithofacies and biotic communities between both reef systems unveil open-marine environment during...

The Late Badenian (=early Serravallian of theMediterranean) chitons of Ukraine, housed in theMuseum of the Earth PAS,Warsaw, are described systematically. Eight species are identified: Leptochiton cancellatus (Sowerby, 1840), Lepidopleurus cajetanus (Poli, 1791), Ischnochiton rissoi (Payraudeau, 1826), Chiton corallinus (Risso, 1826), Chiton olivaceus Spengler, 1797, Lepidochitona lepida (Reuss, 1860), Acanthochitona faluniensis (Rochebrune, 1883) and Craspedochiton profascicularis (Boettger, 1906). Most of the material comes from Varovtsi, in the Khmelnytskyi region. The predominant faunal element is Acanthochitona faluniensis , comprising 55% of all investigated valves.

The Early Sarmatian serpulid-microbialite buildups from the Miodobory region (Ukraine) show unusual facies, biotic and isotopic characteristics, just as earlier studied analogous buildups from the Roztocze region in SE Poland. The growth of the buildups took place in non-marine water typical of the Sarmatian Paratethys, however, at the same time, the water was evaporated, highly supersaturated in respect to calcium carbonate and characterized by anomalous chemistry.

ABSTRACT The study is focused on the determination of the geological age of bivalve fauna recovered from four fossiliferous sequences in the Cacela Formation of Algarve, southern Portugal, by means of the strontium isotope stratigraphy. Forty two analyses of bivalve samples from Barroquinha, Cabanas, the Cacela River and Lacem were performed. The estimated age based on the Sr-87/Sr-86 ratios in bivalve shell samples from the Cacela River (a reference section for the Cacela Formation) is 7.6 +/- 0.4 Ma and is consistent with a late Tortonian age suggested by micropalaeontological data (calcareous nannofossils and planktonic foraminifers). Moreover, strontium isotopic data record that the oldest age of the bivalves of the Cacela Formation (Lacem site) is at least 8.9 +/- 0.4 Ma whilst the age of about 7.0 +/- 0.5 Ma can be inferred for bivalves from Barroquinha. An intriguing new datum comes, however, from the bivalve strontium isotopic data of the Cabanas section which records the estimated age of about 6.7 +/- 0.4 Ma and, therefore, an early Messinian age. This is the first report of the early Messinian marine bivalve fauna in Portugal. Sixty one bivalve species have been recovered in the Messinian of Cabanas. Four of them: Pseudopythina macandrewi (P. Fischer), Coripia corbis (Philippi), Glossus (Glossus) humanus (Linnaeus) and Cyathodonta dollfusi (Cossmann et Peyrot) have previously not been reported from the Miocene of southern Portugal.
