    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.

  • The Carnivora (Mammalia) from the Middle Miocene Locality of Gračanica (Bugojno Basin, Gornji Vakuf, Bosnia and Herzegovina)

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.

    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.

  • 5 the Influence of Character Correlations on Phylogenetic Analyses

However, the fact that most studies of modularity and morphological integration have found significant correlations among many phenotypic traits worryingly calls into question the validity of this assumption. Because gathering data on character correlations for every character in every taxon of interest is unrealistic, studies of modularity are more tractable for assessing the impact of character non-independence on phylogenetic analyses in a real system because modules summarise broad patterns of trait correlations. In this study, we use empirically derived data on cranial modularity and morphological integration in the carnivoran skull to assess the impact of trait correlations on phylogenetic analyses of Carnivora. Carnivorans are a speciose clade of over 270 living species, with an extremely broad range of morphological and dietary diversity, from social insectivores to folivores to hypercarnivores (Nowak, 1999; Myers, 2000). This diversity offers many opportunities to isolate various potential influences on morphology, and, in this case, to study the effects of trait correlations

  • Paleoecological Comparison Between Late Miocene Localities of China and Greece Based on Hipparion Faunas
    Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas Tao DENG Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, Beijing 100044 (China) [email protected] Deng T. 2006. — Paleoecological comparison between late Miocene localities of China and Greece based on Hipparion faunas. Geodiversitas 28 (3) : 499-516. ABSTRACT Both China and Greece have abundant fossils of the late Miocene Hipparion fauna. Th e habitat of the Hipparion fauna in Greece was a sclerophyllous ever- green woodland. Th e Chinese late Miocene Hipparion fauna is represented respectively in the Guonigou fauna (MN 9), the Dashengou fauna (MN 10), and the Yangjiashan fauna (MN 11) from Linxia, Gansu, and the Baode fauna (MN 12) from Baode, Shanxi. According to the evidence from lithology, carbon isotopes, paleobotany, taxonomic framework, mammalian diversity and faunal similarity, the paleoenvironment of the Hipparion fauna in China was a subarid open steppe, which is diff erent from that of Greece. Th e red clay bearing the Hipparion fauna in China is windblown in origin, i.e. eolian deposits. Stable carbon isotopes from tooth enamel and paleosols indicate that C3 plants domi- nated the vegetation during the late Miocene in China. Pollens of xerophilous and sub-xerophilous grasses show a signal of steppe or dry grassland. Forest mammals, such as primates and chalicotheres, are absent or scarce, but grass- land mammals, such as horses and rhinoceroses, are abundant in the Chinese Hipparion fauna. Th e species richness of China and Greece exhibits a similar KEY WORDS trend with a clear increase from MN 9 to MN 12, but the two regions have Hipparion fauna, low similarities at the species level.

    DIPLOMARBEIT KILLING BEHAVIOR IN SMILODON FATALIS (MAMMALIA, CARNIVORA, FELIDAE) BASED ON FUNCTIONAL ANATOMY AND BODY PROPORTIONS OF THE FRONT- AND HIND LIMBS BY JENS-UWE SCHMIEDER GEOLOGISCHES INSTITUT DER EBERHARDT-KARLS-UNIVERSITÄT TÜBINGEN JULY 2000 Jens Schmieder Page II 02.07.2003 Hiermit versichere ich, die vorliegende Arbeit selbständig und nur unter Zuhilfenahme erlaubter und angegebener Hilfsmittel angefertigt zu haben. Tübingen, August 2000. (Jens Schmieder) Jens Schmieder Page III 02.07.2003 Abstract Elongated canines exclusively evolved in carnivores, which are able to stabilize their victims with their anterior extremities. It was shown that power and agility of the front limbs are strongly correlated with the development of sabers. Limb- and skull proportions of the extinct cat Smilodon fatalis were therefore compared with those of six extant species of large felids and those of Canis lupus. Furthermore, differences in hunting behavior and locomotory capabilities were analyzed. Ratios of limb segment lengths have been shown to relate to functional and locomotory differences (e.g., cursoriality) in both extinct and extant felines. S. fatalis is equipped with relatively short and sturdy limbs. Moreover, it possessed a great angle of inclination of the olecranon fossa relative to the long axis of the humerus, in addition to a wide and laterally oriented radial notch. The radial head was more circular than in any other extant cat member. Additionally, the Teres major muscle inserts further away from the shoulder joint and the joints are more powerfully built and demonstrate a great amount of strength and flexibility. It is very likely that Smilodon preyed on the large contemporary megafauna because of its overall more powerful anatomy compared to that of modern felines.

    1 Re-appraisal of 'Felis' pamiri Ozansoy, 1959 (Carnivora, Felidae) from the upper Miocene of 2 Turkey: the earliest pantherin cat? 3 4 Denis GERAADS and Stéphane PEIGNE 5 Centre de Recherche sur la Paléobiodiversité et les Paléoenvironnements (UMR 7207), Sorbonne 6 Universités, MNHN, CNRS, UPMC, CP 38, 8 rue Buffon, 75231 PARIS Cedex 05, France 7 8 Running head: 'Felis' pamiri from Turkey 9 10 Abstract 11 Although the divergence of the Panthera clade from other Felidae might be as old as the 12 earliest middle Miocene, its fossil record before the Pliocene is virtually non-existent. Here we 13 reassess the affinities of a felid from the early upper Miocene of Turkey, known by well-preserved 14 associated upper and lower dentitions. We conclude that it belongs to the same genus 15 (Miopanthera Kretzoi, 1938) as the middle Miocene 'Styriofelis' lorteti (Gaillard, 1899), and that 16 this genus is close to, if not part of, the Panthera clade. 17 18 Keywords: Carnivora – Felidae – Pantherini – Phylogeny – Upper Miocene – Turkey 19 20 Introduction 21 The Felidae can be divided in two subfamilies (Johnson et al. 2006; Werdelin et al. 2010) 22 Felinae (= Pantherinae, or big cats, plus Felinae, or smaller cats, in e.g., Wilson and Mittermeier 23 2009) and Machairodontinae, although their monophyly is hard to demonstrate, the second one 24 being extinct. The Neogene fossil record of the Machairodontinae, or saber-toothed felids, is 25 satisfactory, but that of other members of the family, conveniently called conical-toothed felids 26 (although several of them have compressed, flattened canines) is much more patchy.

Paramachaerodus (Mammalia: Carnivora: Felidae) fossils at the Miocene locality of Ortok, Kyrgyzstan Sophie A. Miller, Paul Z. Barrett, Win N.F. McLaughlin, and Samantha S.B. Hopkins ABSTRACT Dentition from a Miocene hyaenid and a saber-toothed felid are described from the Chu Formation of Kyrgyzstan. Identified as Adcrocuta eximia (UOMNH F-70508) and c.f. Paramachaerodus (UOMNH F-70509), these represent one of the only formal- ized descriptions of fossil taxa from the Miocene in Kyrgyzstan. These specimens were recovered from the Ortok locality at the northwestern corner of the Kochkor Basin, the youngest of the known bone-bed localities in the Chu Formation. Using bio- and mag- netostratigraphy, the Chu Formation is attributed to the late Miocene to Pliocene, deposited approximately at 8 to 4 Ma. The Adcrocuta specimen consists of a partial dentary with condylar and angular processes, one upper, five lower teeth, and the par- tial root and alveoli of a fifth mandibular tooth. The c.f. Paramachaerodus specimen includes a partial M1, P4, and C1, and exhibits the features of the “scimitar-toothed” machairodontines. Preserved diagnostic characters place the Kyrgyz specimen closest to P. ogygia, although with certain features similar to that of P. transasiaticus, such as incipient crenulations on the canine. However, the age of the Kyrgyz specimen, approximately 6 Ma, is substantially younger than what is known for either of these taxa. We therefore hypothesize this Paramachaerodus specimen could be evidence of an endemic taxon in Kyrgyzstan from earlier migrating Asian species, potentially due to geological uplift with the Tien Shan Mountains.
