Puma concolor is currently widespread in South America, but its fossil record is still poorly known in the Continent, particularly in Brazil. Here we report the find of a nearly complete skeleton of P. concolor recovered from underwater Quaternary deposits at the Impossível-Ioiô Cave System, Chapada Diamantina (Bahia, Brazil). The P. concolor remains were found disarticulated but piled together; they

The brown coal mines of the Geiseltal were among the most important middle Eocene fossil localities and constitute the reference sites for the Geiseltalian stage of the European Land Mammal Mega Zones. Here, an updated review of the Geiseltal avifauna is given. Thirteen species are represented by diagnostic bones and can be referred to avian higher-level taxa, but various indeterminable albeit distinct

Pelliales is a basal lineage of the simple thalloid liverworts. Here, we describe a thalloid liverwort from the Middle Jurassic Xishanyao Formation of the Turpan–Hami Basin, Xinjiang Uygur Autonomous Region in northwestern China. The thalloid fossil liverwort is described as a new species: Pellites hamiensis (Pelliaceae, Pelliales). Pellites hamiensis nov. sp. resembles the extant species of Pelliaceae

Together with the rest of the Balkan Peninsula, Greece acted as a refuge for thermophilic amphibians and reptiles during the Quaternary Glaciations. In this work we provide new herpetological data on the latest Early Pleistocene locality of Kaiafas, in western Peloponnese. The site yielded one indeterminate salamandrid urodelan (Salamandridae indet.), one tree frog (Hyla gr. H. arborea), one indeterminate

The Ypresian Cambay Shale Formation at Vastan, Mangrol, and Tadkeshwar lignite mines in Gujarat, western India, has yielded a rich vertebrate fauna including madtsoiid, palaeophiid, booid, and colubroidean-like snakes. The latter are particularly abundant, but their systematic affinities are difficult to resolve. Here we describe new specimens of the colubroidean-like snake Thaumastophis missiaeni

Bouleiceras is a very rare genus among the rich assemblages of ammonoids from the lower Toarcian of the Iberian Range. So far, only two dozen specimens have been recorded in numerous field campaigns carried out since 1965 by different authors. The interest of this taxon lies in its peculiar paleogeographical distribution in comparison with most other ammonoids of the same age. A review of these specimens

A new genus and species of omomyid primate is described from the middle Eocene (Lutetian) Lülük Member of the Uzunçarşidere Formation, Orhaniye Basin, north-central Anatolia, Turkey. This is the first Eocene primate to be reported from the vast area between Switzerland and Pakistan. The new taxon is currently represented by a single dentary fragment, limiting the scope of morphological comparisons

The intrageneric relationships of the pampatheriid genus Scirrotherium and its affinities with supposedly related genera Kraglievichia and Holmesina are revised through new comparative morphological descriptions and parsimony phylogenetic analyses. Unpublished material of pampatheriids (numerous osteoderms, one partial skull and a few postcranial bones) from Neogene formations of Colombia was analyzed

The Cacheuta Hill (Precordillera, Mendoza province, Argentina) is a classic locality of the Gondwanan Triassic. In this contribution, new fossil plant records in the Uspallata Group are described, the systematic palaeontology of previously described taxa is revised, and a comprehensive analysis of the Triassic palaeoflora from Cacheuta Hill is undertaken. The studied unit was correlated with other

The abundance of the major coralline algal groups has been investigated and quantified in the coralline-rich facies of the Miocene shallow-water carbonates of the Eratosthenes Seamount (eastern Mediterranean, off-shore Cyprus). The analysis is based on the quantification of the most easily-recognizable groups of coralline algae in order to provide a user-friendly approach for palaeobathymetric reconstructions

Continuing the study of petrified gymnosperm trunks recovered from the Pedra de Fogo Formation, we identify here two new taxa from the Permian deposits of the Parnaíba Basin, northeastern Brazil. One taxon is an endemic form named Ductolobatopitys mussae Conceição, Neregato et Iannuzzi, nov. gen., nov. sp., characterized by solenoid, lobed and non-septate heterocellular pith, cauline bundles with endarch

Upper Jurassic (Kimmeridgian–Tithonian) and Cretaceous (Berriasian–Barremian) strata of the Ukrainian part of the Carpathian Foredeep basement are rich, at least locally, in crinoid remains. Crinoids belonging to cyrtocrinids (Cyrtocrinida) are represented by whole cups, isolated remains of disarticulated cups, brachial plates and columnals. They are assigned to the following taxa: Cyrtocrinida indet

Scaphitid ammonoids were ubiquitous and significant components of the Western Interior Seaway during the Late Cretaceous. This group is characterized by a recurved hook at maturity that deviates from the juvenile whorls. Such a modification seems counterproductive to active locomotion and to manage a biologically effective orientation that facilitates efficient feeding and swimming. Virtually reconstructed

The Fezouata Shale in Morocco is the only Lower Ordovician Lagerstätte to yield a diverse exceptionally preserved marine fauna. Sediments of this formation have yielded soft to lightly sclerotized taxa that were previously unknown from the Ordovician. Yet the taphonomic pathway of fossils from this formation remains poorly understood. Here, based on drill core material, a close association between

A new sample of 65 specimens representing a minimum number of 15 individuals of the Eurasian antelope Gazellospira torticornis is described from the Lower Pleistocene fossil sites of Dafnero (DFN, N. Greece). The intrapopulation comparisons highlight that several cranial (frontal sinuses, inter-frontal sutures, longitudinal grooves, degree of the horn-cores torsion, and development of anterior keel)

A new conodont species, Siphonodella leiosa, is described from the lower Carboniferous pelagic limestones of the Montagne Noire (France), deposited in North Gondwana on a outer platform environment. Specimens were obtained from one level dated to the Siphonodella jii conodont Zone. The major difference from other siphonodellid conodonts known in this area is that the elements of this new species have

Classifying fossil teeth of Erinaceinae (spiny hedgehogs) is a challenging task, because of their scanty record and systematic treatment that heavily relies on skull characteristics. In this paper we describe the complete set of isolated dental elements of Erinaceinae from the upper Miocene sediments of the Teruel Basin (eastern Central Spain). Four different species were recognized: Postpalerinaceus

Two new taxa of freshwater mussels (Bivalvia: Unionida) from the Aptian Crato Formation of the Araripe Basin, NE Brazil, are described. The fossil bivalves are confined to 30- to 130-cm-thick bioturbated mudstones overlying the fossil-rich laminated limestones of the Crato Formation Konservat-Lagerstätte. Individuals are often preserved with closed or splayed articulated valves, some of them potentially

The first evidence of an ankylosaur from the Late Jurassic Qigu Formation of the southern Junggar Basin (Xinjiang, northwestern China) is described, based on an isolated caudal vertebra that was discovered together with fragmentary remains of other dinosaurs, including stegosaurs, sauropods, and theropods. The caudal vertebra is characterized by the following features: (i) elliptical morphology of

The new crustacean microcoprolite Halorina cryptica nov. ichnogen., nov. ichnosp., is reported from cryptic cavities cutting the Upper Triassic (Carnian to lower Rhaetian) Dachstein-type limestones from the Northern Apuseni Mountains, Romania. The new ichnotaxon is extremely abundant in cavities, neptunian dikes and sills filled with red ferruginous carbonate sediment. The associated microfauna consists

A rock sample obtained from the Caliza Masiva of the San Emiliano Formation (Bashkirian–early Moscovian) in the Mina Profunda area (NE Villamanín) of the Bodón Nappe (Cantabrian Zone, NW Spain) has yielded numerous brachiopods and fish remains not frequently represented in the fossil record. The brachiopod assemblage comprises 13 taxa and is characterized by phosphatic (Langella, Orbiculoidea) as well

Devonian and Carboniferous dendroid graptolites from Belgium are evaluated and partly revised. New finds in two different stratigraphic intervals of the ‘Carrière de Lompret’, an active quarry exploiting Frasnian limestones and shales east of Frasnes-lez-Couvin, allow the identification of Callograptus sp. and Dictyonema fraiponti, both belonging to the dendroid family Acanthograptidae. The relatively

The Mersin Mélange (MM) as a part of the Mersin Ophiolitic Complex in southern Turkey is a sedimentary complex including blocks and tectonic slices within a Late Cretaceous matrix. Two blocks (Keven and Cingeypinari) within the MM originated from the northern branch of Neotethys (Izmir-Ankara-Erzincan Ocean) and have been studied in detail using foraminiferal assemblages to correlate them with coeval

New Pliocene macrofloras and microfloras perfectly preserved from the Mont-Dore (Puy-de-Dôme, Massif central, France) have been reinvestigated. Samples come from different stratigraphical levels collected from three localities, Lac Chambon, La Gratade and Pont de Chocol. The 40Ar/39Ar radiometric datings bracketing the Chambon Lake and La Gratade fossil-bearing horizons give 4.46 ± 0.05 Ma and 3.94 ± 0

Marly sediments of the early Messinian Abad Member of the Turre Formation from the northeastern sector of the Carboneras-Nijar Basin (southern Spain) have yielded a rich fossil assemblage, of which 60 taxa are documented herein. Besides nannoflora and microfauna, this assemblage includes the first autochthonous macrofauna described from the Abad Member. Based on the calcareous nannofossil assemblage

Two new fossil charophyte species from middle Miocene lacustrine deposits of Moneva (Ebro Basin, NE Spain) are described and illustrated. Sphaerochara miocenica nov. sp. is represented by medium sized gyrogonites with a characteristic spheroidal shape and ornamented with numerous small and regularly spaced tubercles arranged along the spiral cells. Several specimens show an unusual carbonate encrusted

As a contribution to the still open debate on the multiple african origins of the domesticated donkey, this work focuses on the wild ass of the Maghreb. It follows the recent paleontological review of the equids from Lac Karâr, a middle Pleistocene site in Northern Algeria, where most of the faunal remains were attributed to wild asses (Equus africanus Heuglin and Fitzinger, 1866). The morphometric

Two specimens of Campinasuchus dinizi (CPPLIP 1319 and CPPLIP 1360) belonging to Baurusuchidae (Crocodyliformes, Notosuchia) from the Upper Cretaceous Bauru Group of Minas Gerais state (Brazil) were scanned in a Toshiba Aquilion 64 CT machine. Based on these data, it was possible to identify and reconstruct the paranasal sinuses, the nasal cavity proper, the nasopharyngeal duct, the encephalon, the

Bulk sampling and surface collecting of two glauconitic horizons located in Southern Togo yielded a diverse elasmobranch fauna described here. This fauna includes 30 species dominated by carcharhiniforms (eleven species), myliobatiforms (nine species) and lamniforms (five species); it also comprises three orectolobiforms, whereas the squatiniforms and rhinopristiforms are represented by one species

Field investigations of the Palaeogene sections exposed in Barmer district, Rajasthan (India) led to the discovery of a new fossiliferous horizon in the Padma Rao Open Cast Bentonitic Clay Quarry. The bentonitic clay sequence of this quarry is considered as representing the upper part of the shale, carbonaceous shale, lignite and bentonitic clay succession of the Akli Formation exposed in the Giral

New discoveries on the ichnological site known as “the Pterosaur Beach of Crayssac” (lower Tithonian, Upper Jurassic; south-western France) answer the question of terrestrial capabilities of non-pterodactyloid pterosaurs. If the terrestrial type of locomotion of pterodactyloid pterosaurs has been solved from ichnological evidence for more than twenty years, no tracks and trackways referable to non-pterodactyloid

The Ordovician Radiation was among the most extensive intervals of diversification in the history of life. However, a delineation of the proximal cause(s) of the Radiation remains elusive. Any such determination should involve an analysis of geographic overprints on diversification: did the Radiation occur randomly around the world or, alternatively, was it focused in particular geographic or depositional

L’originalité des dépôts sédimentaires et des faunes d’ammonites du jebel Bou Rharraf repose sur la présence de faciès « Ammonitico Rosso », les plus occidentaux connus pour le Pliensbachien, une forte diversité des Phylloceratida (Phylloceras, Calaiceras, Zetoceras, Partschiceras et Juraphyllites) et une disparité morphologique importante chez les Galaticeras, Miltoceras et les Tauromeniceras. Si

Three new species of fossil snipe flies (Insecta, Diptera, Rhagionidae) from the Daohugou Formation of Chifeng City in Nei Monggol Autonomous Region (= Inner Mongolia), northeastern China are described as Palaeobolbomyia sinica nov. sp., Ussatchovia robusta nov. sp. and Ussatchovia gracilenta nov. sp. They represent the first records of the genera Palaeobolbomyia Kovalev and Ussatchovia Kovalev in

A comprehensive outline of the Jurassic ammonoid superfamily Aequiloboidea is here presented: this group is known from? Rhaetian-early Hettangian to early Pliensbachian and it is exclusively found within the Mediterranean Tethys (Austrian Alps, Bavarian Prealps, Tuscany, Umbria-Marche and Abruzzi Apennines, Morocco, Tunisia, western Hungary). On the basis of the available documentation, it is composed

Microremains of various sharks, actinopterygians and crocodiles have been recovered from two sites in the Douiret Formation and three sites in the Aïn el Guettar Formation in southern Tunisia. The presence of an actinistian is also suggested based on histological study of hemisegments of lepidotrichia. Convergence in dental enameloid microstructure between neoselachian sharks and actinopterygians sharing

The taxonomy of the calcareous nannofossil Arkhangelskiella is revised using the results of a biometric analysis performed on 599 specimens from various stratigraphic levels throughout the upper Campanian-Maastrichtian of the Stevns-1 borehole, Denmark. Combined qualitative labelling and biometric measurements suggest that this genus comprises at least three distinct morphogroups in this stratigraphic

The dental morphology of Pascualgnathus polanskii Bonaparte (Therapsida, Eucynodontia, Traversodontidae), from the Middle Triassic Río Seco de la Quebrada Formation (Puesto Viejo Group, Argentina), is described and compared with that of other basal traversodontid cynodonts. Albeit Pascualgnathus is frequently used in phylogenetic analyses, neither a detailed description nor drawings of its postcanines

The taxonomic revision of the carbonate microbiota of the limestone lenses intercalated into the Carboniferous siliciclastic series of Balia-Maden (Turkey) shows that most lenses are early or middle Brigantian in age (latest Visean), only a single lens being of younger age (late Serpukhovian). Calcareous microbiota are abundant in the Balia-Maden lenses carbonates. Microfacies analysis shows the dominance

A revision of Chamaeleo caroliquarti Moody and Roček is presented. The comparisons of the holotypic left dentary with those of specimens subsequently assigned to C. caroliquarti and of the Recent species of Chamaeleo, Furcifer and Calumma is carried out. It is shown that the type dentaries of C. caroliquarti include two different morphotypes with the absence of unique features. Within the Recent chameleons

In order to study the adaptive significance of the nasal chamber in felids (Mammalia, Carnivora), we measured the nasal aperture area and used it as an indirect estimate of the nasal chamber volume. We assume that this measurement relates to the metabolic demands for oxygen by animals, which in turn would depend on their mass, hunting techniques and/or the environment inhabited. The proven relationship

The antillocaprinid rudist bivalve Antillosarcolites Chubb is revised based on abundant specimens from the Campanian of Jamaica. Two genera are recognised: Antillosarcolites, type species Antillosarcolites macgillavryi Chubb, and Parantillosarcolites nov. gen., type species Parantillosarcolites lenticularis nov. gen., nov. sp. These two genera are characterised by distinct myocardinal arrangements

Successive growth stages of P1-elements in the Middle to early Late Triassic species Pseudofurnishius murcianus allows the observation of a detailed ontogeny. Besides the gradual enlargement of its curved blade and the growing number of its denticles, a small internal platform develops, eventually followed by an external one, both bearing denticles. The number of denticles on the blade and internal

A monospecific assemblage of myodocopid ostracods has been found in the Middle Devonian of a unique hydrothermal vent system of Hamar Laghdad (eastern Anti-Atlas, southern Morocco), which developed over a submarine eruption of basaltic rocks. This fauna has been recovered from a neptunian dyke representing the sediment infill of an Eifelian venting fissure discovered in the central part of Hamar Laghdad

In this paper we describe a new species of Hypolagus coming from an early Pliocene karstic deposit near Caló den Rafelino (Manacor, Mallorca). It represents the westernmost European record for the genus. The faunal assemblage of this deposit represents an early phase of the second insular faunal episode of Mallorca, related with the Messinian regressive episode (latest Miocene). Although the postcranial

In this paper we present the effects of different tracemakers on the redistribution of calcareous nannofossils throughout the K-Pg boundary at the Bidart section (SW France), along with their consequences for our knowledge of the K-Pg boundary event. Danian calcareous nannofossil assemblages are present in Maastrichtian samples due to infiltration into dark trace fossil infillings proceeding from the

The new genus Cieneguiticeras, assigned to the family Oppeliidae, is described on the basis of Andean lower-middle Tithonian ammonites from Arroyo Cieneguita, west-central part of the Neuquén-Mendoza Basin, Argentina. The macroconchs are closely homoeomorphic with Neochetoceras Spath and the microconchs have a ‘glochiceratid’-type morphology. The stratigraphic range of Cieneguiticeras nov. gen. includes

New taxonomic study of the “old collection” of Carnivora from Petralona Cave, associated to the well-known hominid skull, housed in the Geology School of the Thessaloniki Aristotle University since 1960, revealed 11 species (Canis arnensis, Lycaon lycaonoides, Vulpes praeglacialis, Ursus deningeri, U. spelaeus, U. arctos, Pliocrocuta perrieri, Pachycrocuta brevirostris, Crocuta crocuta, Panthera leo

Intensive sampling of the Tulong Formation in South Tibet has facilitated the construction of a highly-resolved middle and late Smithian ammonoid succession. The new biostratigraphical sequence comprises the middle Smithian Brayardites compressus beds, Nammalites pilatoides beds, and the Nyalamites angustecostatus beds followed by the late Smithian Wasatchites distractus beds and Glyptophiceras sinuatum

The material belonging to the holotype of Rayososaurus agrioensis Bonaparte is redescribed. The great development of the acromion process, directed in a markedly posterior direction, and the ventral margin of the scapula with a strong ventrodistal expansion, interpreted as autapomorphies of the taxon, justify the validity of the species. Although the material is rather fragmentary, the racquet-shaped

Ten different types of microproblematic structures occur on the surfaces, and in epidermal and hypodermal cells of fern pinnules preserved in the Late Pennsylvanian Grand-Croix cherts from France. These include thick-walled spheres, some with a prominent exit site, aggregations of variously sized spheres that may be surrounded by a membrane or sheath, a cylindrical structure composed of polygonal compartments

A distinct large vole lineage involving three species from the Late Pliocene – Early Pleistocene of China is morphologically and quantitatively delineated. A special sinuous line (linea sinuosa) pattern, not previously recognized, diagnoses the new lineage, and distinguishes the species in the lineage from all other vole genera known either from China or elsewhere. At present, only two morphologically

The study of abundant permineralized fern remains collected in the Oligocene Rancahué Formation (Neuquén Province, Argentina) allowed the identification of two different taxa. The name Cuyenopteris patagoniensis nov. gen., nov. sp. is proposed for several stems and fronds characterized by the presence of caulinar dictyosteles with root gaps, producing C-shaped leaf traces composed by two hippocampiform

The depositional history of the Name Chamber at the Sterkfontein early hominid site is complex, as is the case with most such cavities. Unravelling this history may therefore benefit from the input of less usual lines of evidence to complement baseline geological investigations. In this case, micromammalian remains from the Western Talus of the Name Chamber provide tentative evidence for the depositional

Dans plusieurs synclinaux du Haut Atlas central, les « Couches rouges » succédant à la fermeture du sillon marin atlasique téthysien au cours du Jurassique moyen sont constituées par trois formations ou unités successives de dépôts continentaux ayant fait l’objet de datations biostratigraphiques récentes. Des marqueurs micropaléontologiques, essentiellement des charophytes et des ostracodes, permettent

This paper summarizes the results of investigations carried out in the Mokrá quarry since 2006 on the biostratigraphy of the Tournaisian-Visean (T-V) boundary interval. It also integrates previous results obtained by J. Kalvoda and collaborators. The main focus is on the boundary itself, but stratigraphically lower and higher levels have been investigated as well to provide a biostratigraphical context

An assemblage of Phlycticeras Hyatt from a precisely dated zone of Middle Callovian in Kutch, India has been analyzed. Systematic study reveals that this sample can be divided into two size groups. The larger set shows different adult modifications leading to ornamental polymorphism. Polymorphs are very similar, if not identical, to different chronospecies of Europe, which range between Middle to Upper

Sinocalopteryx shangyongensis nov. gen., nov. sp., the first fossil calopterygoid from eastern Asia, is described from the earliest Eocene of Southwest China. Although the new genus has the principle synapomorphies of Calopterygoidea, it possesses a unique structure (possible reversal) in the pattern of vein RP1/2.

Sublethal injuries, the effects of which are seen as regeneration patterns, are described from Late Bajocian and Bathonian (Middle Jurassic) ammonites from Poland (Polish Jura area) for the first time. The total number of ammonite shells bearing signs of sublethal injuries is small (only 11 specimens, which constitute ∼1.2% of all ammonites investigated), and this value is even smaller (∼0.3 to 0.8%)

Les niveaux du Crétacé qui affleurent à Somolinos (Chaîne Ibérique, Espagne) ont été étudiés depuis longtemps d’un point de vue stratigraphique, sédimentologique et paléontologique. Une très riche faune d’ammonites, échinoïdes et rudistes a été décrite mais jusqu’à présent, ces niveaux n’avaient jamais été échantillonnés pour une étude palynologique. Nous avons effectué l’analyse palynologique de deux
