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 . -
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.

Hyaenodonts and Carnivorans from the Early Oligocene to Early Miocene of Xianshuihe Formation, Lanzhou Basin, Gansu Province, China
Palaeontologia Electronica http://palaeo-electronica.org HYAENODONTS AND CARNIVORANS FROM THE EARLY OLIGOCENE TO EARLY MIOCENE OF XIANSHUIHE FORMATION, LANZHOU BASIN, GANSU PROVINCE, CHINA Xiaoming Wang, Zhanxiang Qiu, and Banyue Wang ABSTRACT Fieldwork in the 1990s produced a few records of carnivorous mammals (cre- odonts and carnivorans) in the early Oligocene through early Miocene of Lanzhou Basin, Gansu Province, China. Although only five taxa are known so far, most repre- sented by fragmentary material, the new carnivore assemblage is unique and shows little resemblance to faunas elsewhere in eastern Asia. The early Oligocene record is represented by a single premolar of a Hyaenodon, referable to H. pervagus. In the early Miocene, a new species of Hyaenodon, H. weilini sp. nov., represented by sev- eral cheek teeth, is the last record of this genus in east Asia. A horizontal ramus of an amphicyonid, here identified as Ictiocyon cf. I. socialis, is the first record of this taxon in Asia, and a very small musteloid lower carnassial, although difficult to identify to genus, is clearly a new record because nothing of this small size has been known in Asia. The overall faunal composition seems to suggest affinity with northern Eurasia rather than southern Asia. Xiaoming Wang.

AMERICAN MUSEUM NOVITATES Published by THz AmERICAN MUSEUM OF NATURAL HISTORY Number 485 New York City Aug. 25, 1931 56.092T EXPLORATIONS, RESEARCHES AND PUBLICATIONS OF PIERRE TEILHARD DE CHARDIN, 1911-1931 WITH MAP AND LEGEND SHOWING CHIEF FOSSIL COLLECTING AREAS OF CHINA, 1885-1931 By HENRY FAIRFIELD OSBORN In recent years the Department of Vertebrate Paleontology of the American Museum has enjoyed the cooperation of Pierre Teilhard de Chardin, especially in the Eocene fauna of France from the Paleocene stage up to the close of the Phosphorites or Lower Oligocene time, also through explorations and researches first reported to the Mus6e National d'Histoire Naturelle of Paris in the year 1920. The Ameri- can Museum Central Asiatic Expedition of the summer of 1930 was fortunate in obtaining the cooperation of Teilhard in the field. On February 10, 1931, he addressed the Osborn Research Club and sum- marized the results of his explorations in China, accompanying his address by the map which is reproduced herewith. The present article is prepared as a brief outline of the principal observations made by Teil- hard in the Eocene of France and Belgium and as a summary of the observations made in China, concluding with an abstract of the address of February 10 above mentioned, a bibliography of his writings now contained in the Osborn Library of the American Museum, and a map showing twenty-three of the chief fossil collecting areas of China pre- pared by Teilhard for the present publication. OLIGOCENE TO MIDDLE EOCENE Under the direction of Marcellin Boule, now the ranking verte- brate palheontologist of France, Teilhard began his studies in 1911 with a synthetic review of the creodonts and true carnivores, of the PHOS- PHORITES DU QUERCY, the famous fissure horizon of Eocene to Oligo- cene age, tracing their phylogeny (1915, p. -

An Arctomorph Carnivoran Skull from the Phosphorites Du Quercy and the Origin of Procyonids
An arctomorph carnivoran skull from the Phosphorites du Quercy and the origin of procyonids MIECZYSEAW WOLSAN and BRIGI'ITE LANGE-BAD& Wolsan, M. & Lange-BadrC, B. 1996. An arctomorph carnivoran skull from the Phosphorites du Quercy and the origin of procyonids. Acta Palaeontologica Poloni- ca 41, 3, 277-298. The size and morphological characteristics of a skull of an arctomorph carnivoran mammal from Mouillac (old collection of the Phosphorites du Quercy, of unknown age) in France closely match those of the holotype of the earliest known procyonid Pseudobassaris riggsi and another skull referred to this species, both from old collections of the Phosphorites du Quercy (Caylus and Mouillac), probably earliest Late Oligocene in age. The skull is more primitive in morphology than those of ~seudobassarisrig&i and every other known procyonid, approaching a hypothetical primitive procyonid morphotype. The only, but methodologically fundamental, departure from this morphotype is the lack of the procyonid supra- meatal fossa, which is the crucial synapomorphy of the family Procyonidae. To explain the phylogenetic and taxonomic status of the arctomorph represented by the skull, three competing hypotheses are put forward. Hypothesis A, which considers the arctomorph as an individual of Pseudobassaris riggsi, assumes that the procyonid suprameatal fossa first appeared in a common ancestor of Pseudo- bassaris and other procyonids but was still of variable occurence within Pseudo- bassaris riggsi. Hypothesis B, which proposes the arctomorph as a member of a new Pseudobassaris species ancestral to Pseudobassaris riggsi, concludes that the procyonid suprameatal fossa arose in Pseudobassaris riggsi and in the Procyonidae independently, excluding Pseudobassaris from the procyonids. -
Macaques at the Margins: the Biogeography and Extinction of Macaca Sylvanus in Europe. Sarah Elton1 and Hannah J. O'regan2 1D
Macaques at the margins: the biogeography and extinction of Macaca sylvanus in Europe. Sarah Elton1 and Hannah J. O’Regan2 1Department of Anthropology, Durham University, Durham, DH1 3LE 2Department of Archaeology, University of Nottingham, University Park Nottingham, NG7 2RD. KEYWORDS Miocene, Pliocene, Pleistocene, primate, fossil, modelling, Eurasia, time budgets ABSTRACT The genus Macaca (Primates: Cercopithecidae) originated in Africa, dispersed into Europe in the Late Miocene and resided there until the Late Pleistocene. In this contribution, we provide an overview of the evolutionary history of Macaca in Europe, putting it into context with the wider late Miocene, Pliocene and Pleistocene European monkey fossil record (also comprising Mesopithecus, Paradolichopithecus, Dolichopithecus and Theropithecus). The Pliocene and Pleistocene European Macaca fossil material is largely regarded as Macaca sylvanus, the same species as the extant Barbary macaque in North Africa. The M. sylvanus specimens found at West Runton in Norfolk (53°N) during the Middle Pleistocene are among the most northerly euprimates ever discovered. Our simple time-budget model indicates that short winter day lengths would have imposed a significant constraint on activity at such relatively high latitudes, so macaque populations in Britain may have been at the limit of their ecological tolerance. Two basic models using climatic and topographic data for the Last Interglacial and the Last Glacial Maximum alongside Middle and Late Pleistocene fossil 1 distributions indicate that much of Europe may have been suitable habitat for macaques. The models also indicate that areas of southern Europe in the present day have a climate that could support macaque populations. However, M. sylvanus became locally extinct in the Late Pleistocene, possibly at a similar time as the straight-tusked elephant, Palaeoloxodon antiquus, and narrow-nosed rhinoceros, Stephanorhinus hemitoechus. -

The section is easily accessible, well exposed, suitable for field excursions, and well documented in terms of carbonate lithofacies, depositional sequences and stable- isotope chemostratigraphy. The late Tonian Ombombo Subgroup is 355 m thick above the basal Beesvlakte Formation, which is not included in the section due to poor outcrop and complex structure. The early- middle Cryogenian Abenab Subgroup is 636 m thick and the early Ediacaran Tsumeb Subgroup is 1020 m thick. While the section is complete in terms of formations represented, the Ombombo and lower Abenab subgroups have defined gaps due to intermittent uplift of the northward-sloping Makalani rift shoulder. The upper Abenab and Tsumeb subgroups are relatively thin due to erosion of a broad shallow trough during late Cryogenian glaciation and flexural arching during post-rift thermal subsidence of the carbonate platform. -
