Abstract. Late Middle Miocene (Upper Badenian) strata of the Fore-Carpathian Depression of Poland yield a shallow-water ostracod fauna which contains the species Triebelina raripila (G. W. Müller, 1894) and Carinocythereis carinata (Roemer, 1838). The palaeobiogeographic distribution of the two main species suggests, that in the late Middle Miocene, Central Paratethys was still connected to the Mediterranean, although still separated from the Eastern Paratethys and from southeastern Eurasia. The continuous occurrence of Triebelina raripila and Carinocythereis carinata in the Mediterranean basins, from the Early Miocene to Recent, indicates that marine conditions existed throughout, thereby allowing them to survive the Late Miocene salinity crisis.

A late Burdigalian bathyal mollusc fauna from the Vienna Basin (Slovakia)This is the first record of a bathyal mollusc fauna from the late Early Miocene of the Central Paratethys. The assemblage shows clear affinities to coeval faunas of the Turin Hills in the Mediterranean area and the Aquitaine Basin in France. The overall biostratigraphic value of the assemblage is hard to estimate due to the general very poor knowledge of Miocene bathyal faunas. Several species, however, are known from deep water deposits of the Middle Miocene Badenian stage as well. This implies Early Miocene roots of parts of the Middle Miocene deep water fauna and suggests a low turnover for bathyal mollusc communities at the Early-Middle Miocene boundary. The nassariid gastropodNassarius janschloegliHarzhauser nov. sp. and the naticid gastropodPolinices cerovaensisHarzhauser nov. sp. are introduced as new species.

Temporal Dimensions

Introduction: Scutelliforms were diverse and widespread in shallow marine environments during Neogene times in South America. Nevertheless, they have almost never been used as biostratigraphic tools. Objective: To provide a refined stratigraphic frame useful for calibrating temporal dimensions of scutelliform diversity from Argentina and Uruguay and its correlation with the molluscan assemblages previously proposed. Methods: A detailed survey of their geographic and stratigraphic provenance was carried out. We revised both the bibliography and collections (institutional and from our own field work). Results: The group is represented by 14 species belonging to six genera, and four assemblages were identified. Numerical dates of the Neogene marine rocks obtained recently allowed their placement in a chronological scheme: “Iheringiella” sp. A is restricted to the late Oligocene, the genera Camachoaster and “Eoscutella” and the species Monophoraster telfordi to the early Miocene, Abertella gualichensis and Abertella miskellyi to the middle Miocene, and Monophoraster duboisi, Amplaster coloniensis and Amplaster ellipticus to the late Miocene. Non-lunulate scutelliforms are not restricted to the late Oligocene as previously supposed. The oldest occurrence of the genus Monophoraster corresponds to the early Miocene, and along with Iheringiella are long-living taxa that embrace the 25.3 Ma-18.1 Ma (Iheringiella patagonensis) and approximately 15 Ma-6.48 Ma (Monophoraster darwini) intervals. The presence of Iheringiella in the early Miocene of northeastern Patagonia is corroborated, reaching there its northernmost distribution. Monophoraster darwini has a temporal range from the late Miocene (where it was previously thought to be restricted) back to the middle Miocene, since this is the species yielded in the well-known and discussed “Monophoraster and Venericor Beds”. Conclusions: The Paleogene-Neogene scutelliforms of Argentina and Uruguay range from the late Oligocene to the late Miocene. There is a good correspondence among the numerical ages, molluscan biozones and scutelliform assemblages.

The cricetid rodents from Gratkorn (Austria, Styria): a benchmark locality for the continental Sarmatiansensu stricto(late Middle Miocene) in the Central ParatethysThe recent discovery of a terrestrial vertebrate assemblage in the clay pit St. Stefan at Gratkorn (Austria, Styrian Basin) is of major importance for our understanding of the evolution of late Middle Miocene mammal assemblages in the Paratethys realm. The cricetid rodent assemblage includes four species:Megacricetodon minutusDaxner, 1967,Democricetodonsp. nov. (sensuKälin & Engesser 2001),Eumyarionsp., and "Cricetodon" fandlisp. nov. The latter species belongs to the "Cricetodon" fandli-C. klariankaeHír, 2007 lineage, which allows for a long-distance correlation with other late Middle Miocene/earliest Late Miocene European localities. The biostratigraphic conclusions drawn from the study of the fossils from Gratkorn concurs with the age estimates based on regional geology, paleomagnetic measurements, and the gastropod-based biostratigraphy at the base of the Late Sarmatians. str.(late Serravallian, latest Volhynian), around 12-12.2 Ma (Chron C5An.1n) ago.

Molluscan Species

Pectinids are the most abundant and widely distributed taxa in the Tertiary marine beds of Patagonia. Along with other very common molluscan species, they characterize five assemblages, from oldest to youngest: 1) the Oligocene Panopea sierrana-Parinomya patagonensis Assemblage; 2) the Late Oligocene–Early Miocene Jorgechlamys centralis–Reticulochlamys borjasensis Assemblage; 3) the Early Miocene Reticulochlamys zinsmeisteri–Struthiolarella patagoniensis–Pleuromeris cruzensis Assemblage; 4) the Early Miocene Pseudoportlandia glabra–Antimelatoma quemadensis Assemblage; and 5) the latest Early Miocene–earliest Middle Miocene Nodipecten sp.–Venericor abasolensis–Glycymerita camaronesia Assemblage. A brief analysis of the origin and composition of these Tertiary Patagonian molluscan faunas is provided. Striking compositional changes occurred through time, recorded mainly in the Late Paleocene, Late Eocene, Late Oligocene–Early Miocene, and Late Miocene.

Geology of the Čoka structure in northern Banat (Central Paratethys, Serbia)The Čoka structure is a fault-bounded anticline in northern Banat, in the southern part of the Neogene Pannonian Basin. The structure and its vicinity were explored by 24 wells. In addition to well logs, paleontological, sedimentological and petrological analyses of cores and 27 seismic sections with different parameters of acquisition and processing were used for geological investigation of the area. The E-SE dipping pre-Neogene basement consists of Lower Triassic clastics and, in the NW part of the study area, Paleozoic greenschists. Thin Middle Miocene (Badenian) sediments unconformably overlie the basement and pinch out towards the elevated NW part of the study area. They are also missing in some wells on the apex of the Čoka structure, probably due to erosion. Badenian sediments were deposited in a shallow marine environment. The late Middle Miocene (Sarmatian) strata are missing and the Badenian is directly overlain by Upper Miocene (Pannonian) sediments. The latter also pinch out towards the NW but in contrast to Badenian sediments, they are present in all boreholes on the Čoka structure. Pannonian deposition took place in a caspibrackish environment of Lake Pannon, with predominance of marls and fine-grained clastics. Pannonian sediments are conformably overlain by latest Miocene (Pontian) and Pleistocene lacustrine, alluvial and terrestrial sediments.

Abstract. Mediocris commenticius n. gen., n. sp. is herein described as a kentriodontid dolphin from the Sarmatian (late Middle Miocene) of south Hungary, territory of the ancient Central Paratethys Sea. The type specimen is an incomplete skeleton including a distorted skull and mandibles with teeth, ear bones, elements of both flippers, and numerous vertebrae. Mediocris commenticius has a nasal bone morphology that differs from all delphinoid taxa, but is most similar to members of the Pithanodelphininae Barnes, 1985. The nasals are triangular, not inflated, have a faint anterolateral notch, and diverge posteriorly. On the basis of the nasal bone morphology, the new species shows affinities to Pithanodelphis, and is less derived than Atocetus and Sarmatodelphis. Due to the incompleteness of the cranial vertex of the type and only known skull, however, the species is only tentatively referred to the subfamily Pithanodelphininae. Mediocris commenticius n. gen., n. sp. wird als Kentriodontide aus dem Sarmatium (spätes Mittelmiozän) von Südungarn beschrieben, aus dem Gebiet des ehemaligen zentral-paratethyschen Meeres. Der Holotypus ist ein unvollständiges Skelett; erhalten sind der zusammengepresste Schädel, Unterkiefer mit Zähnen, Gehörknochen, Knochenelemente beider Brustflossen sowie zahlreiche Wirbel. Die Morphologie der Nasale der neuen Art unterscheidet sich von allen beschriebenen Taxa der Kentriodontidae, weist aber auf Verwandtschaft mit den Pithanodelphinen hin. Die Nasalia sind dreieckig, nicht extrem vergrößert, sie haben eine schwach ausgebildete anterolaterale Kerbe und sie divergieren in caudaler Richtung. Anhand der Morphologie der Nasale steht M. commenticius der Art Pithanodelphis cornutus nahe und ist weniger stark spezialisiert als Atocetus und Sarmatodelphis. Wegen der unvollständigen Erhaltung des cranialen Vertex ist Mediocris commenticius allerdings nur mit Vorbehalt in die Unterfamilie Pithanodelphininae einzuordnen. doi:10.1002/mmng.200410004

The Family

Turkey is known for the wealth of fossil suids found in deposits of middle Miocene, late Miocene and Plio-Pleistocene levels but material of this family from early Miocene and Palaeogene deposits is rare in the country, one of the few published occurrences being from Şemsettin (Kumartaş Formation, MN 4, Çankiri-Çorum Basin). For this reason, it is interesting to record the presence of small suid remains in the Soma Formation at Sabuncubeli (Manisa, SW Anatolia) in deposits correlated to MN 3 (early Miocene) and thus the earliest known Turkish members of the family. The upper and lower teeth are herein attributed to a new genus and species (Prolistriodon smyrnensis) of Listriodontinae because, in a nascent way, they show a suite of derived morphological features such as upper central incisors with apical sulci, and upper molars with lingual precrista, found in listriodonts but not in Kubanochoerinae, Palaeochoerinae, Tetracondontinae, Hyotheriinae, Namachoerinae, Cainochoerinae or Suinae.
