The Carnivora (Mammalia) from the Middle Miocene Locality of Gračanica (Bugojno Basin, Gornji Vakuf, Bosnia and Herzegovina)
Palaeobiodiversity and Palaeoenvironments https://doi.org/10.1007/s12549-018-0353-0 ORIGINAL PAPER The Carnivora (Mammalia) from the middle Miocene locality of Gračanica (Bugojno Basin, Gornji Vakuf, Bosnia and Herzegovina) Katharina Bastl1,2 & Doris Nagel2 & Michael Morlo3 & Ursula B. Göhlich4 Received: 23 March 2018 /Revised: 4 June 2018 /Accepted: 18 September 2018 # The Author(s) 2018 Abstract The Carnivora (Mammalia) yielded in the coal mine Gračanica in Bosnia and Herzegovina are composed of the caniform families Amphicyonidae (Amphicyon giganteus), Ursidae (Hemicyon goeriachensis, Ursavus brevirhinus) and Mustelidae (indet.) and the feliform family Percrocutidae (Percrocuta miocenica). The site is of middle Miocene age and the biostratigraphical interpretation based on molluscs indicates Langhium, correlating Mammal Zone MN 5. The carnivore faunal assemblage suggests a possible assignement to MN 6 defined by the late occurrence of A. giganteus and the early occurrence of H. goeriachensis and P. miocenica. Despite the scarcity of remains belonging to the order Carnivora, the fossils suggest a diverse fauna including omnivores, mesocarnivores and hypercarnivores of a meat/bone diet as well as Carnivora of small (Mustelidae indet.) to large size (A. giganteus). Faunal similarities can be found with Prebreza (Serbia), Mordoğan, Çandır, Paşalar and Inönü (all Turkey), which are of comparable age. The absence of Felidae is worthy of remark, but could be explained by the general scarcity of carnivoran fossils. Gračanica records the most eastern European occurrence of H. goeriachensis and the first occurrence of A. giganteus outside central Europe except for Namibia (Africa). The Gračanica Carnivora fauna is mostly composed of European elements. Keywords Amphicyon . Hemicyon . -

[Un nuevo Lagomorfo del Mioceno superior de Chad (África central).] Revista Española de Paleontología, 22 (), -20. ISSN 023-6937. ABSTRACT A new species of the genus Serengetilagus Dietricht 94, here named S. tchadensis n. sp., is described from Toros Menalla deposits, Late Miocene of Djurab Erg (North Chad, central Africa). It shows primitive features, such as a simple archaeolagine-type p3, with only two main external folds, and upper cheek teeth strongly widened with wear. Its size and skeletal features resemble S. praecapensis Dietricht 94 from the Middle Pliocene of Laetoli (Tanzania). They differ in several cranial and dental features (choanae width, zygoma, orbits, basicranial-basi- facial angle, lack of hypoflexus in P2, short and asymmetric hypoflexus in P3-M2, lack of lingual folds in p3, etc). Individual variations in S. tchadensis n. sp. approach S. praecapensis, such as an incipient anteroflexid and a forward-curved hypoflexid in some p3. -
Oldest Mephitine Cranium and Its Implications for the Origin of Skunks
Oldest mephitine cranium and its implications for the origin of skunks MIECZYSEAW WOLSAN Wolsan, M. 1999. Oldest mephitine cranium and its implications for the origin of skunks. -Acta Palaeontologica Polonica 44,2,223-230. -- Recent molecular studies have recognized the skunks (Mephitinae) to be the sister taxon of a clade comprising the Procyonidae and Mustelidae. These findings are inconsistent with the traditional placement of the skunks among mustelids, which is based on mor- phological evidence from extant taxa. This paper reports on a well-preserved cranium of a young individual, recovered from the middle Miocene deposits (MN 7+8, about 11-12 Ma) of Steinheim am Albuch, Germany. The fossil is the holotype of Palaeo- mephitis steinheimensis Jager, 1839, which is here recognized as a senior subjective syn- onym of Trochotherium cyamoides Fraas, 1870 (consequently, Palaeomephitis Jager, 1839 is a senior subjective synonym of Trochotherium Fraas, 1870). The specimen is identified as the oldest and most primitive mephitine cranium known to date, approach- ing the primitive morphology for the Mephitinae. It exhibits a combination of mephitine (accessory middle-ear chamber, lateral swelling of the squamosal) and mustelid (mus- telid suprameatal fossa) synapomorphies,corroborating the view that skunks are derived from a mustelid ancestor. Its auditory bulla shows a slightly inflated and relatively large caudal entotympanic, which indicates that the uninflated and relatively small caudal entotympanics of adult mephitines, as well as their hypertrophied ectotympanics, are not primitive (as hitherto assumed) but derived, providing a synapomorphy that supports a sister-group relationship between the Mephitinae and Lutrinae. Key words : Palaeomephitis, Trochotherium,Mephitinae, Mustelidae, Carnivora, phy- logeny, taxonomy, morphology. -

EURASIAN MIDDLE AND LATE MIOCENE HOMINOID PALEOBIOGEOGRAPHY AND THE GEOGRAPHIC ORIGINS OF THE HOMININAE by Mariam C. Nargolwalla A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Anthropology University of Toronto © Copyright by M. Nargolwalla (2009) Eurasian Middle and Late Miocene Hominoid Paleobiogeography and the Geographic Origins of the Homininae Mariam C. Nargolwalla Doctor of Philosophy Department of Anthropology University of Toronto 2009 Abstract The origin and diversification of great apes and humans is among the most researched and debated series of events in the evolutionary history of the Primates. A fundamental part of understanding these events involves reconstructing paleoenvironmental and paleogeographic patterns in the Eurasian Miocene; a time period and geographic expanse rich in evidence of lineage origins and dispersals of numerous mammalian lineages, including apes. Traditionally, the geographic origin of the African ape and human lineage is considered to have occurred in Africa, however, an alternative hypothesis favouring a Eurasian origin has been proposed. This hypothesis suggests that that after an initial dispersal from Africa to Eurasia at ~17Ma and subsequent radiation from Spain to China, fossil apes disperse back to Africa at least once and found the African ape and human lineage in the late Miocene. The purpose of this study is to test the Eurasian origin hypothesis through the analysis of spatial and temporal patterns of distribution, in situ evolution, interprovincial and intercontinental dispersals of Eurasian terrestrial mammals in response to environmental factors. Using the NOW and Paleobiology databases, together with data collected through survey and excavation of middle and late Miocene vertebrate localities in Hungary and Romania, taphonomic bias and sampling completeness of Eurasian faunas are assessed. -

Phylogenetic Relationships and Evolutionary History of the Dental Pattern of Cainotheriidae
Palaeontologia Electronica palaeo-electronica.org A new Cainotherioidea (Mammalia, Artiodactyla) from Palembert (Quercy, SW France): Phylogenetic relationships and evolutionary history of the dental pattern of Cainotheriidae Romain Weppe, Cécile Blondel, Monique Vianey-Liaud, Thierry Pélissié, and Maëva Judith Orliac ABSTRACT Cainotheriidae are small artiodactyls restricted to Western Europe deposits from the late Eocene to the middle Miocene. From their first occurrence in the fossil record, cainotheriids show a highly derived molar morphology compared to other endemic European artiodactyls, called the “Cainotherium plan”, and the modalities of the emer- gence of this family are still poorly understood. Cainotherioid dental material from the Quercy area (Palembert, France; MP18-MP19) is described in this work and referred to Oxacron courtoisii and to a new “cainotherioid” species. The latter shows an intermedi- ate morphology between the “robiacinid” and the “derived cainotheriid” types. This allows for a better understanding of the evolution of the dental pattern of cainotheriids, and identifies the enlargement and lingual migration of the paraconule of the upper molars as a key driver. A phylogenetic analysis, based on dental characters, retrieves the new taxon as the sister group to the clade including Cainotheriinae and Oxacron- inae. The new taxon represents the earliest offshoot of Cainotheriidae. Romain Weppe.

E-mail: [email protected] Abstract The Linxia Basin, Gansu Province, China, is known for its abundant and well-preserved fossils. Here a new species, Chleuastochoerus linxiaensis sp. nov., is described based on specimens collected from the upper Miocene deposits of the Linxia Basin, distinguishable from C. stehlini by the relatively long facial region, more anteromedial-posterolaterally compressed upper canine and more complicated cheek teeth. A cladistics analysis placed Chleuastochoerus in the sub- family Hyotheriinae, being one of the basal taxa of this subfamily. Chleuastochoerus linxiaensis and C. stehlini are con- sidered to have diverged before MN 10. C. tuvensis from Russia represents a separate lineage of Chleuastochoerus, which may have a closer relationship to C. stehlini but bears more progressive P4/p4 and M3. Key words: Linxia Basin, upper Miocene Liushu Formation, Hyotheriinae, Chleuastochoerus, phylogeny Introduction Chleuastochoerus Pearson 1928 is a small late Miocene-early Pliocene fossil pig (Suidae).
