The Carnivora of the Edson Local Fauna (Late Hem- phillian), Kansas. Smithsonian Contributions to Paleobiology, number 54, 42 pages, 18 figures, 1983.—The late Hemphillian Edson Quarry Local Fauna contains 36 species of amphibians, reptiles, birds, and mammals. The eight species of carnivorans are Cams davisi, a primitive dog; Osteoborus cyonoides, a large borophagine; Agnotherium species, a long-limbed bear; Plesiogulo marshalli, a wolverine; Pliotaxidea nevadensis, a badger; Martinogale alveodens, a skunk; Adel- phatlurus kansensis, a metailurine felid; and Machairodus coloradensis, a machai- rodontine felid. Edson is one of several fossil localities in Sherman County, Kansas, and was deposited in a series of fine sands within the Ogallala Formation. A secondary channel in a braided stream system is proposed as the environment of deposition. The high percentage of juveniles, as well as the vast numbers of the salamander Ambystoma kansensis, indicate accumulation during the spring of the year. The Edson Quarry Local Fauna compares very well with such typically late Hemphillian faunas as Coffee Ranch, Texas, and Optima, Oklahoma. Although only the carnivorans have been treated in depth, a listing of the vertebrate taxa is offered as well. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.

Because of the scarcity of fossil remains, the anatomy of this felid has been very poorly known. However, the recently discovered Miocene carnivore trap of Batallones-1, near Madrid, Spain, has yielded almost complete skeletons of this animal, which is now one of the best known machairodontines. Consequently, the machairodont adaptations of this primitive sabre-toothed felid can be assessed for the first time. Some characters, such as the morphology of the mastoid area, reveal an intermediate state between that of felines and machairodontines, while others, such as the flattened upper canines and verticalized mandibular symphysis, show clear machairodont affinities.

  • Carnivora from the Late Miocene Love Bone Bed of Florida
    Bull. Fla. Mus. Nat. Hist. (2005) 45(4): 413-434 413 CARNIVORA FROM THE LATE MIOCENE LOVE BONE BED OF FLORIDA Jon A. Baskin1 Eleven genera and twelve species of Carnivora are known from the late Miocene Love Bone Bed Local Fauna, Alachua County, Florida. Taxa from there described in detail for the first time include the canid cf. Urocyon sp., the hemicyonine ursid cf. Plithocyon sp., and the mustelids Leptarctus webbi n. sp., Hoplictis sp., and ?Sthenictis near ?S. lacota. Postcrania of the nimravid Barbourofelis indicate that it had a subdigitigrade posture and most likely stalked and ambushed its prey in dense cover. The postcranial morphology of Nimravides (Felidae) is most similar to the jaguar, Panthera onca. The carnivorans strongly support a latest Clarendonian age assignment for the Love Bone Bed. Although the Love Bone Bed local fauna does show some evidence of endemism at the species level, it demonstrates that by the late Clarendonian, Florida had become part of the Clarendonian chronofauna of the midcontinent, in contrast to the higher endemism present in the early Miocene and in the later Miocene and Pliocene of Florida.

    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 .

    THE PEARCE-SELLARDS Series NUMBER 19 THE GENUS DINOFELIS (CARNIVORA, MAMMALIA) IN THE BLANCAN OF NORTH AMERICA by BJORN KURTEN Submitted for publication May 30, 1972 TEXAS MEMORIAL MUSEUM / 24TH & TRINITY / AUSTIN, TEXAS W. W. NEWCOMB, JR., DIRECTOR The Genus Dinofelis (Carnivora, Mammalia) in the Blancan of North America Bjorn Kurten* INTRODUCTION The Blanco fauna was described by Meade (1945), who created the new on a felid species Panthera palaeoonca , based skull and associated mandible. Comparing the new species with members of the genera Panthera and Felis, he concluded that it showed close affinity to the jaguar. This has been tenta- tively accepted by later workers (Savage, 1960). The species forms the basis for the record of the genus Panthera in the Blancan of North America. A restudy of the material in 1971 led to the discovery in the collections of the Texas Memorial Museum at the University of Texas at Austin, of an additional, better preserved specimen (an upper canine) which clearly did not belong to Panthera or Felis but showed close affinity to the genus Dino- felis which has hitherto only been recorded from the Old World. Checking back on the type skull and mandible, the reference to Dinofelis could be fully substantiated. I wish to express my gratitude to Drs. John A. Wilson and Ernest L. Lundelius, the University of Texas at Austin, for the opportunity to study collections in their care. The abbreviation TMM is used to signify collections of the Texas Memorial Museum, the University of Texas at Austin.

  • Mammalia, Felidae, Canidae, and Mustelidae) from the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas
    Chapter 9 Carnivora (Mammalia, Felidae, Canidae, and Mustelidae) From the Earliest Hemphillian Screw Bean Local Fauna, Big Bend National Park, Brewster County, Texas MARGARET SKEELS STEVENS1 AND JAMES BOWIE STEVENS2 ABSTRACT The Screw Bean Local Fauna is the earliest Hemphillian fauna of the southwestern United States. The fossil remains occur in all parts of the informal Banta Shut-in formation, nowhere very fossiliferous. The formation is informally subdivided on the basis of stepwise ®ning and slowing deposition into Lower (least fossiliferous), Middle, and Red clay members, succeeded by the valley-®lling, Bench member (most fossiliferous). Identi®ed Carnivora include: cf. Pseudaelurus sp. and cf. Nimravides catocopis, medium and large extinct cats; Epicyon haydeni, large borophagine dog; Vulpes sp., small fox; cf. Eucyon sp., extinct primitive canine; Buisnictis chisoensis, n. sp., extinct skunk; and Martes sp., marten. B. chisoensis may be allied with Spilogale on the basis of mastoid specialization. Some of the Screw Bean taxa are late survivors of the Clarendonian Chronofauna, which extended through most or all of the early Hemphillian. The early early Hemphillian, late Miocene age attributed to the fauna is based on the Screw Bean assemblage postdating or- eodont and predating North American edentate occurrences, on lack of de®ning Hemphillian taxa, and on stage of evolution.

  • Mammalia: Carnivora) in the Americas: Past to Present
    Journal of Mammalian Evolution https://doi.org/10.1007/s10914-020-09496-8 ORIGINAL PAPER Environmental Drivers and Distribution Patterns of Carnivoran Assemblages (Mammalia: Carnivora) in the Americas: Past to Present Andrés Arias-Alzate1,2 & José F. González-Maya3 & Joaquín Arroyo-Cabrales4 & Rodrigo A. Medellín5 & Enrique Martínez-Meyer2 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Understanding species distributions and the variation of assemblage structure in time and space are fundamental goals of biogeography and ecology. Here, we use an ecological niche modeling and macroecological approach in order to assess whether constraints patterns in carnivoran richness and composition structures in replicated assemblages through time and space should reflect environmental filtering through ecological niche constraints from the Last Inter-glacial (LIG), Last Glacial Maximum (LGM) to the present (C) time. Our results suggest a diverse distribution of carnivoran co-occurrence patterns at the continental scale as a result of spatial climatic variation as an important driver constrained by the ecological niches of the species. This influence was an important factor restructuring assemblages (more directly on richness than composition patterns) not only at the continental level, but also from regional and local scales and this influence was geographically different throughout the space in the continent. These climatic restrictions and disruption of the niche during the environmental changes at the LIG-LGM-C transition show a considerable shift in assemblage richness and composition across the Americas, which suggests an environ- mental filtering mainly during the LGM, explaining between 30 and 75% of these variations through space and time, with more accentuated changes in North than South America.

    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.
