Tragoportax cf. rugosifrons (Schlosser, 1904) from the late Miocene of Cessaniti (Southern Italy)

This paper describes remains attributable to Tragoportax cf. rugosifrons (Schlosser, 1904) found in the late Miocene site of Cessaniti (Vibo Valentia, Calabria) and the surrounding area. The studied specimens come from the Clypeaster sandstones, included in a marine/fluvial succession dated between 8 and 7.2 Ma. At Cessaniti, Tragoportax is associated with Stegotetrabelodon syrticus Petrocchi, 1941; Samotherium cf. boissieri Forsyth-Major, 1888; Bohlinia cf. attica Matthew, 1929; and an undetermined Rhinocerotid still under study. The genus Tragoportax was common in Eurasia and Africa during the late Miocene. The occurrence of Tragoportax cf. rugosifrons at Cessaniti confirms the peculiarity of the assemblage, with its association of species of North African and Pikermian (Greco-Iranian bioprovince) affinities.     

First giraffid skulls (Bohlinia attica) from the late Miocene Maragheh fauna,Northwest Iran

An almost complete skull and a second partial skull of Bohlinia attica (Artiodactyla: Giraffidae) from the late Miocene of Maragheh in northwestern Iran is described along with a complete upper dentition from Samos in Greece. These specimens enrich what is known of this species. The skull has massive bent ossicones. The braincase is horizontal to the face in lateral view. The upper premolars have strongly curved styles. The metapodials of this species are elongate with a deep plantar trough. The braincase is short and the occipital does not extend caudally. The type material of Bohlinia is from Pikermi but this taxon is also known from localities in F.Y.R.O. Macedonia, Greece, Turkey, Bulgaria, Iraq, and Iran. The new specimens are similar to others except that the ossicone terminates in a knob and the palatine choanae are positioned caudally. This taxon along with Honanotherium, which is most similar but with shorter metapodials and simpler premolars, can be placed in the subfamily Bohlininae.     

Systematics,palaeoecology and palaeobiogeography of the Neogene fossil sharks from the Azores (Northeast Atlantic)

The Azores Archipelago is a group of isolated islands located in the North Atlantic Ocean. One of these oceanic islands – Santa Maria – exhibits marine fossiliferous sediments of late Miocene/early Pliocene and also of Pleistocene age. Recent research provided new selachian fossil material, with three new records (Carcharias acutissima, Megaselachus megalodon, and Carcharhinus cf. leucas) increasing the number of fossil sharks reported from the Azores (Santa Maria Island) to seven species (Notorynchus primigenius, C. acutissima, Cosmopolitodus hastalis, Paratodus benedenii, Isurus oxyrinchus, M. megalodon, and C. cf. leucas). So far, no teeth of batoids or small sharks have been found despite the screen-washing of several sediment samples from Santa Maria. The Azorean Mio-Pliocene selachian fauna clearly differs from those described from sediments deposited on continental shelves, in which batoids and small benthic sharks (e.g., scyliorhinids) are usually well represented. During the late Miocene/early Pliocene, subtropical to warm-temperate seas were prevalent in the area of the Azores, as deduced from palaeontological, geological and isotopic data, all indicating a warmer climate than in the present.     

Musteloids and feloids (Mammalia, Carnivora) from the late Miocene locality of Pikermi (Attica, Greece)

Some relatively rare carnivore remains from Pikermi are studied. The present specimens include Simocyon primigenius(ROTH and WAGNER, 1854), Promeles palaeatticus(WEITHOFER, 1888), Martes woodwardiPILGRIM, 1931, Felis atticaWAGNER, 1857 and Machairodus giganteus(WAGNER, 1848), as well as some postcranial remains that resemble Enhydriodon? latipesPILGRIM, 1931 and are assigned to Mustelidae gen. et spec. indet. Some of these species were not known until now but from their holotypes as M. woodwardi and E.? latipes. Other species such as F. attica and M. giganteus are better known but from relatively scant material. Since the material of the earlier mentioned species comes from Pikermi, their type locality, it is of especial importance and improves our knowledge for the Pikermi carnivores and their relationships to other species. In some cases where the material comes from ossiferous blocks, the accompanying faunal context is discussed.     

Serpulids and other calcareous tube-dwelling encrusting polychaetes from the Early Cretaceous Agrio Formation (Neuquén Basin,Argentina)

Serpulids and other related tube-dwelling polychaetes are often ignored when found as fossil remains. They are, however, a widespread and important group today, and abundant literature has been published on them. Knowledge of fossil serpulids is centered on European material, and little has already been done on South American fossil calcareous tubes. In this paper, seven serpulid and sabellid morphotypes are described from the Early Cretaceous marine Agrio Formation of Argentina, revealing a diversity of worms recorded as encrusters on bivalves, ammonites and corals. Sabellids are represented by Glomerula cf. serpentina. Serpulids are represented by two subfamilies: “Serpulinae” includes Mucroserpula mucroserpula, Parsimonia antiquata, Placostegus cf. conchophilus, Propomatoceros semicostatus and P. sulcicarinatus; Spirorbinae is represented by heavily worn tiny coiled tubes assigned to ?Neomicrorbis. Serpulids and sabellids are one of the main components of the mollusk-encrusting fauna recorded in the Agrio Formation, along with small oysters but much more diverse. They are most commonly found as post-mortem encrusters, but some cases of unquestionable living interaction are also found, such as serpulid tubes embedded on coral branches. They are often overgrown by bryozoans, and sometimes by oysters; they frequently occur aggregated.     

Coastal evolution and Holocene ostracods in Melides lagoon (SW Portugal)

A multidisciplinary study covering sedimentology (texture, carbonate and organic matter content, clay mineralogy), geochemistry (major, minor and trace elements, isotopes), palaeoecolgy (ostracods) and isotopic dating (¹⁴C) has been carried out on two long cores (MB-40.0 m and MIGM-34.0 m) retrieved from the barrier and the alluvial plain margining the Melides lagoon (south-western coast of Portugal). The interpretation of the whole data set allowed the establishment of an evolutionary model for this lowland since the Late Glacial. This model includes four stages. It starts with a fluvial terrestrial environment, replaced by an estuarine to fully marine one (circa 9500 cal BP), due to the rapid rise in sea level recorded during the first phase of the Holocene transgression. The deceleration of sea level rise favoured the emplacement of a sandy barrier (circa 5900 cal BP) that promoted the differentiation of a coastal lagoon which has been progressively filled with fluvial sediments.The ostracod fauna in both locations includes 38 species of littoral to sublittoral/phytal marine forms (mainly Urocythereis britannica, Carinocythereis whitei, Loxoconcha rhomboidea, Pontocythere elongata, Semicytherura sella, Semicytherura acuta, Basslerites cf. berchoni, Hiltermannicythere emaciata) and brackish water forms (Cyprideis torosa, Loxoconcha elliptica), which clearly characterize the signature of both the marine and lagoonal episodes, respectively.     

Species of Nectria (Ascomycetes,Hypocreales) having orange perithecia and colorless,striate ascospores

Nine species ofNectria are described or redescribed. Ascospores of all are colorless and striates; their perithecia are orange and do not become red in KOH. Three groups of species are represented. One group includesNectria grammicospora, N. cf.grammicospora, N. subquaternata, and the new species:N. grammicosporopsis, N. lucifer, andN. neogrammicospora. A second group includes the new speciesN. chlorogloea andN. septomyrotheciae. The third group is represented by the single new speciesN. dacryocarpa. The life-cycles of these species are described. Anamorphs ofN. grammicospora, N. grammicosporopsis, N. lucifer, andN. subquaternata are species ofClonostachys. The anamorph, ofN. neogrammicospora isAcremonium- orCephalosporiopsis-like in having monophialidic conidiophores and phragmosporous conidia, and that ofN. cf.grammicospora isAcremonium-like with amerosporous conidia. The anamorphs ofN. chlorogloea andN. septomyrotheciae have green conidia. The anamorph ofN. chlorogloea isMyrothecium sp.; its conidia are unicellular and the conidioma is a synemma. The anamorph ofN. septomyrotheciae isSeptomyrothecium cf.uniseptatum; its conidioma is a sporodochium and the conidia are bicellular. The new genus and speciesDacryoma alba are described for the anamorph ofN. dacryocarpa. All of these fungi are pantropical or Australasian in distribution.     

Ammonites du Toarcien du Haut Atlas central (Maroc)

In the central High Atlas, the Toarcian Stage is represented by a marl and marly limestone series of variable thickness. Two sections have been studied: Amellago (500 m) and Aït Athmane (100 m). Ammonites from the two sections allowed to characterize the Polymorphum, Levisoni, Bifrons, Gradata, and Speciosum zones. The Polymorphum Zone provided, among others: Dactylioceras (Eodactylites) mirabile, D. (E.) pseudocommune, Dactylioceras (Orthodactylites) aff. crosbeyi and Neolioceratoides aff. hoffmanni; the Levisoni Zone provided a rich ammonite fauna composed of, Calliphylloceras nilssoni, Dactylioceras (Orthodactylites) cf. semiannulatum, Eleganticeras exaratum, Harpoceras falciferum, H. pseudoserpentinum, H. serpentinum, H. subplanatum, Hildaites cf. forte, H. levisoni, H. cf. serpentiniformis, H. cf. subserpentinus, H. striatus, H. wrighti, Lytoceras siemensi, Lytoceras sp., Maconiceras soloniacense, Phylloceras sp., Polyplectus pluricostatum et Polyplectus sp.; the Bifrons Zone provided Eleganticeras sp., Harpoceras subplanatum?, Hildoceras bifrons, H. lusitanicum, H. semipolitum, H. sublevisoni, Hildoceras sp., Porpoceras gr. vortex – verticosum; the Gradata Zone was characterized by Pseudocrassiceras bayani, P. frantzi, Pseudocrassiceras sp., Pseudocrassiceras sp. indet.; and the Speciosum Zone provided an Hammatoceras aff. insigne. These species have been described and illustrated for the first time for the central High Atlas. Most of them are common to several basins of the north Tethyan margin and the Subboreal Domain of NW Europe.     

Late Messinian rodents from Verduno (Piedmont,NW Italy): Biochronological,paleoecological and paleobiogeographic implications

The stratigraphic and paleoenvironmental context of the Verduno fossil vertebrate locality is discussed herein based on its rodent record. The Verduno section crops out in the southern part of the Tertiary Piedmont Basin (TPB), and can be included in the Messinian post-evaporitic Cassano Spinola Fm., chronologically corresponding to the so-called Lago-Mare event. Rodents are represented by a relatively rich assemblage. Murids are by far the most diverse and abundant, with at least four taxa, including the common Centralomys benericettii and Paraethomys meini, and the rare Apodemus gudrunae and Occitanomys sp. Cricetids are represented by a single species, Apocricetus cf. A. barrierei. Muscardinus aff. M. vireti appears to be the only glirid present at Verduno. The Verduno rodent assemblage shares some taxa with other Messinian post-evaporitic localities from Italy bearing continental vertebrate remains, such as Brisighella (central Italy) and Moncucco Torinese (NW Italy) (e.g., C. benericettii, P. meini) and, possibly, with Ciabòt Cagna (NW Italy). However, the general structure of these four Messinian assemblages displays substantial differences, which may reflect different palaeoenvironmental conditions.     

Assessment of genetic diversity among and within Carthamus species using sequence-related amplified polymorphism (SRAP) markers

Due to precise evaluation of genetic diversity of Carthamus species, sixty-two genotypes consisting fifty-two from five wild (C. oxyacanthus M. Bieb, C. lanatus L., C. dentatus Vahl, C. boissieri Halácsy, C. glaucus M.B.) and ten from cultivated species (C. tinctorius L.) were selected for evaluation of the genetic diversity in Carthamus species. A total of 238 (81.2 %) polymorphic bands were detected by 12 SRAP primer combinations with an average of 22 bands per combination. Me4-Em1 and Me5-Em2 primer combinations were known as the most informative SRAP markers based on the PIC values (0.34) where they distinguished all studied Carthamus species. Cluster analysis classified all accessions into five main groups among which clusters containing cultivated individuals were distinctly separated from those containing wilds. The most and the least genetic variation based on analysis of molecular variance, were detected within (76.90 %) and among (22.84 %) groups, respectively. The obtained results suggested that C. dentatus, C. glaucus and C. boissieri species may be classified in one section including C. dentatus in one and C. glaucus and C. boissieri in another subsection. The results also revealed high genetic similarity between C. oxyacanthus and C. tinctorius despite their different morphological characteristics.     

Les grands mammifères du Villafranchien supérieur des travertins du Bassin de Denizli (Sud-Ouest Anatolie,Turquie)

The large mammals from travertine deposits in the Denizli basin include the following species: Archidiskodon meridionalis meridionalis, Equus cf. altidens s. l., E. cf. apolloniensis, Stephanorhinus cf. etruscus, Metacervoceros rhenanus, Cervalces (Libralces) ex gr. minor-gallicus, Palaeotragus sp., Bovinae gen. and sp. indet. This association resembles those from the late Villafranchian of Southern and Eastern Europe, and, to some extent, fromWestern Asia, and could be older than 1.2 Ma.     

The fossil Bovidae (Artiodactyla, Mammalia) from Gesher Benot Ya'aqov, Israel: Out of Africa during the Early-Middle Pleistocene transition

We report the study of the collection of fossil bovid specimens from the Early-Middle Pleistocene Acheulian site of Gesher Benot Ya‘aqov. This locality, situated in the Levantine Corridor (the bottleneck that connects Africa and Eurasia) is a key site to explain the faunal and human dispersals out of Africa during the Matuyama/Brunhes boundary around 0.8 Ma. Two species of bovine (Bos sp., and Bovini gen. et sp. indet. cf. Bison sp.), one antelope (Gazella sp. cf. G. Gazella), and another indeterminate Bovidae gen. et sp. indet., have been recorded. The largest species, Bos sp., is an African immigrant related to the species from the Eritrean site of Buia, Bos buiaensis, which evolved from the buffalo of Olduvai Pelorovis oldowayensis, and colonized the Eurasian continent in parallel with the dispersal of the Acheulian culture into the northern continent. Numerous important species first recorded in several localities of Early-Middle Pleistocene transition from Eurasia are included in this dispersal out of Africa, including the megaherbivore, Palaeoloxodon antiquus, and the carnivores Crocuta crocuta, and later, Panthera leo and Panthera pardus. This faunal turnover is coincident with the change to colder climates that dominated the Middle Pleistocene.     

A new Ruscinian site in Europe: Baza-1 (Baza basin,Andalusia, Spain)

The Guadix–Baza depression (southeastern Spain) preserves one of the best continental Plio-Pleistocene records of the European continent. The new site, Baza-1, is the first Ruscinian locality with fauna of large vertebrates known in the basin. During the summer seasons of 2001, 2002, 2015 and 2016, systematic excavations were undertaken in the site over an area of 25 m², which provided > 400 fossil remains of Ruscinian mammals. The faunal assemblage is diverse, comprising 17 genera. Rodentia are represented by Ruscinomys sp., Apocricetus barrierei, Debruijnimys julii, Apodemus gorafensis, Castillomys gracilis, Occitanomys cf. brailloni, Paraethomys meini, Paraethomys aff. abaigari, Stephanomys cordii, Trilophomys cf. castroi and Eliomys aff. intermedius. Large mammals are represented by two proboscideans, Anancus arvernensis and Mammut borsoni, the rhino Stephanorhinus sp. cf. S. jeanvireti, the equid cf. Hipparion sp., two bovids, a large sized Alephis sp. and a small-to-middle sized Bovidae indet. (cf. Antilope sp.), and a middle sized deer, Cervinae indet. This record is completed by the presence of a chelonid, Testudinae indet. Biostratigraphic data from micro and macromammals suggest an age for the assemblage between 4 and 4.5 Ma.     

Distribution and taxonomy of shallow marine Ostracods from Northern Socotra Island (Indian Ocean) - Yemen

Forty-seven species belonging to 30 genera of ostracods have been identified from Recent shallow marine sediments collected along the northern coastline of the island of Socotra (Indian Ocean). The systematics and distribution of these ostracods are discussed. Three genera, Loxoconcha, Bosasella, and Xestoleberis are found to have high species diversity. The species Loxoconcha ghardaqensis, Moosella striata are best documented in the Red Sea and Gulf of Aden while Kotoracythere inconspicua and Triebelina sertata were found to be the most widespread species. The fauna shows a close affinity to other ostracod assemblages of the Indo-Pacific region, East African coast and Red Sea.     

Biodiversity of Klebsormidium (Streptophyta) from alpine biological soil crusts (Alps,Tyrol, Austria,and Italy)

Forty Klebsormidium strains isolated from soil crusts of mountain regions (Alps, 600–3,000 m elevation) were analyzed. The molecular phylogeny (internal transcribed spacer rDNA sequences) showed that these strains belong to clades B/C, D, E, and F. Seven main (K. flaccidum, K. elegans, K. crenulatum, K. dissectum, K. nitens, K. subtile, and K. fluitans) and four transitional morphotypes (K. cf. flaccidum, K. cf. nitens, K. cf. subtile, and K. cf. fluitans) were identified. Most strains belong to clade E, which includes isolates that prefer humid conditions. One representative of the xerophytic lineage (clade F) as well as few isolates characteristic of temperate conditions (clades B/C, D) were found. Most strains of clade E were isolated from low/middle elevations (<1,800 m above sea level; a.s.l.) in the pine‐forest zone. Strains of clades B/C, D, and F occurred sporadically at higher elevations (1,548–2,843 m a.s.l.), mostly under xerophytic conditions of alpine meadows. Comparison of the alpine Klebsormidium assemblage with data from other biogeographic regions indicated similarity with soil crusts/biofilms from terrestrial habitats in mixed forest in Western Europe, North America, and Asia, as well as walls of buildings in Western European cities. The alpine assemblage differed substantially from crusts from granite outcrops and sand dunes in Eastern Europe (Ukraine), and fundamentally from soil crusts in South African drylands. Epitypification of the known species K. flaccidum, K. crenulatum, K. subtile, K. nitens, K. dissectum, K. fluitans, K. mucosum, and K. elegans is proposed to establish taxonomic names and type material as an aid for practical studies on these algae, as well as for unambiguous identification of alpine strains. New combination Klebsormidium subtile (Kützing) Mikhailyuk, Glaser, Holzinger et Karsten comb. nov. is made.     

Early Miocene Amphibians (Caudata, Salientia) from the Mokrá-Western Quarry (Czech Republic) with comments on the evolution of Early Miocene amphibian assemblages in Central Europe

The Mokrá-Western Quarry exhibits the rare occurrence of Early Miocene (MN 4) vertebrate fauna within the area of the eastern part of Central Europe. In addition to a rich fauna of reptiles and mammals, two fossiliferous karst joints (Mokrá-Western Quarry, 1/2001 Turtle Joint and Mokrá-Western Quarry, 2/2003 Reptile Joint) yielded a rich fauna of amphibians including 13 amphibian taxa: Salamandridae: Mioproteus sp., Chelotriton sp., type I, Chelotriton sp., type II, Triturus aff. roehrsi, Triturus cf. marmoratus, Triturus sp. (T. cristatus species group), Chioglossa meini, Mertensiella mera, Salamandridae gen. and sp. indet.; Pelobatidae: Pelobates sanchizi; Ranidae: Rana sp. (synklepton Rana esculenta); Bufonidae: Bufo sp. The first records of the West European species Triturus cf. marmoratus and Chioglossa meini are reported from the eastern part of Central Europe indicating the wide distribution of those taxa throughout the whole of Europe as early as MN 4. The oldest known record of Pelobates sanchizi documents the Early Miocene presence of representatives closely related to the extinct Late Oligocene representatives of Pelobates. The slow evolution of amphibian species is documented by the presence of Triturus cf. marmoratus and the oldest known occurrence of the extinct salamander Mertensiella mera.     

Middle to Late Pleistocene herpetofauna from Scladina and Sous-Saint-Paul caves (Namur,Belgium)

For the first time, the fossil herpetofauna from the Middle and Late Pleistocene of Scladina and Sous-Saint-Paul caves (Sclayn, Belgium) is described. The amphibians and squamate reptiles are represented by one salamander (Salamandra salamandra), three anurans (Pelodytes punctatus, Bufo bufo and Rana temporaria), two lizards (Lacerta cf. agilis and Anguis fragilis) and two snakes (Zamenis longissimus and Vipera cf. berus). The occurrence of the Parsley Frog (Pelodytes punctatus) and the Aesculapian Snake (Zamenis longissimus), which are not currently represented in Belgium, is of particular interest. Scladina also represents one of the northernmost fossil mentions for the Fire Salamander (Salamandra salamandra) although it is within its current distribution in Europe. Finally, the presence of the Adder (Vipera cf. berus) is very probably attested in Scladina whereas today this snake is infrequent and classified as endangered in Belgium.     

Cenomanian-Turonian rudists from Western Sinai, Egypt: Systematic paleontology and paleoecology

The Cenomanian-Turonian sequence is well exposed in western central Sinai and contains a considerable number of rudist species. The identified rudists belong to Radiolitidae, Hippuritidae and Requieniidae. Fifteen species are described, belonging to ten genera: Requienia, Toucasia, Apricardia, Radiolites, Eoradiolites, Praeradiolites, Sphaerulites, Sauvagesia, Hippurites, and Vaccinites. Eleven species are reported in the Cenomanian and four species in the Turonian. Within the Cenomanian, two new species are described: Requienia tortuosi and Eoradiolites lenisexternus. The genus Requienia and the species Apricardia carentonenis d’Orbigny, Eoradiolites syriacus (Conrad), Sphaerulites agariciformis Delamétherie, Sphaerulites depressus Blanckenhorn and Vaccinites cf. grossouvrei (Douvillé) are reported for the first time from Egypt. The Cenomanian and Turonian rudists in the western Sinai show either elevator or clinger morphotypes, with the predominance of the former type; recumbent mode of life is rarely represented by some Requieniidae. The elevators are of isolated and clustered occurrences and more represented in the Cenomanian sequence. Rudists of the study area are mainly of parautochthonous fabrics with low to dense packing. Autochthonous fabrics are also achieved by some species, mainly in the Turonian. The disappearance of rudists from the middle part of the sequence and above the Cenomanian/Turonian boundary is due to a deeper setting that resulted from sea-level rise or seafloor subsidence (shelf drowning). The occurrence of rudists with oysters and other benthic fossils in the siliciclastic and carbonate sediments of the Cenomanian and Turonian sedimentary rocks in the Sinai indicate that the sequence was deposited on a broad, shallow shelf. Although the first marine transgression invaded the central Sinai in the late Cenomanian, transgressive deepening conditions continued until the Turonian. The rudists of central Sinai are of Tethyan affinity with significant relation with North Africa, the Middle East, and Southern Europe.     

New remains of Hyaenodontidae (Creodonta,Mammalia) from the Oligocene of Central Mongolia

New specimens of hyaenodontid creodonts are described which were unearthed in Mongolia by the Austrian–Mongolian Paleontological expeditions. Five taxa are identified: Hyaenodon eminus, Hyaenodon pervagus, Hyaenodon cf. incertus, Hyaenodon cf. mongoliensis, and cf. Hyaenodon gigas. Hitherto unknown morphological details are reported for most of these species. The implications to systematic of the species and the genus Hyaenodon are discussed. These Hyaenodon remains suggest a separate evolutionary lineage, with different species in Europe and Asia, even if the genus is also known from contemporary faunas of Europe and North America.
