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. -
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. -

Chapter 1 - Introduction
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. -
First Nimravid Skull from Asia Alexander Averianov1,2, Ekaterina Obraztsova3, Igor Danilov1,2, Pavel Skutschas3 & Jianhua Jin1
www.nature.com/scientificreports OPEN First nimravid skull from Asia Alexander Averianov1,2, Ekaterina Obraztsova3, Igor Danilov1,2, Pavel Skutschas3 & Jianhua Jin1 Maofelis cantonensis gen. and sp. nov. is described based on a complete cranium from the middle- upper Eocene Youganwo Formation of Maoming Basin, Guangdong Province, China. The new taxon Received: 08 September 2015 has characters diagnostic for Nimravidae such as a short cat-like skull, short palate, ventral surface of petrosal dorsal to that of basioccipital, serrations on the distal carina of canine, reduced anterior Accepted: 21 April 2016 premolars, and absence of posterior molars (M2-3). It is plesiomorphic nimravid taxon similar to Published: 10 May 2016 Nimravidae indet. from Quercy (France) in having the glenoid pedicle and mastoid process without ventral projections, a planar basicranium in which the lateral rim is not ventrally buttressed, and P1 present. The upper canine is less flattened than in other Nimravidae.Maofelis cantonensis gen. and sp. nov. exemplifies the earliest stage of development of sabertooth specialization characteristic of Nimravidae. This taxon, together with other middle-late Eocene nimravid records in South Asia, suggests origin and initial diversification of Nimravidae in Asia. We propose that this group dispersed to North America in the late Eocene and to Europe in the early Oligocene. The subsequent Oligocene diversification of Nimravidae took place in North America and Europe, while in Asia this group declined in the Oligocene, likely because of the earlier development of open habitats on that continent. Nimravids are cat-like hypercarnivores that developed saber-tooth morphology early in the Cenozoic and were top predators in the late Eocene – late Oligocene mammal communities of the Northern Hemisphere1–3. -
O Ssakach Drapieżnych – Część 2 - Kotokształtne
PAN Muzeum Ziemi – O ssakach drapieżnych – część 2 - kotokształtne O ssakach drapieżnych - część 2 - kotokształtne W niniejszym artykule przyjrzymy się ewolucji i zróżnicowaniu zwierząt reprezentujących jedną z dwóch głównych gałęzi ewolucyjnych w obrębie drapieżnych (Carnivora). Na wczesnym etapie ewolucji, drapieżne podzieliły się (ryc. 1) na psokształtne (Caniformia) oraz kotokształtne (Feliformia). Paradoksalnie, w obydwu grupach występują (bądź występowały w przeszłości) formy, które bardziej przypominają psy, bądź bardziej przypominają koty. Ryc. 1. Uproszczone drzewo pokrewieństw ewolucyjnych współczesnych grup drapieżnych (Carnivora). Ryc. Michał Loba, na podstawie Nyakatura i Bininda-Emonds, 2012. Tym, co w rzeczywistości dzieli te dwie grupy na poziomie anatomicznym jest budowa komory ucha środkowego (bulla tympanica, łac.; ryc. 2). U drapieżnych komora ta jest budowa przede wszystkim przez dwie kości – tylną kaudalną kość entotympaniczną i kość ektotympaniczną. U kotokształtnych, w miejscu ich spotkania się ze sobą powstaje ciągła przegroda. Obydwie części komory kontaktują się ze sobą tylko za pośrednictwem małego okienka.

In the present paper we describe five bacula attributed to the bear Indarctos arctoides Depe´ret, 1895 from the Batallones-3 site (Madrid Basin, Spain). Both the length and morphology of this fossil bacula enabled us to make interpretative approaches to a series of ecological and ethological characters of this bear. Thus, we suggest that I. arctoides could have had prolonged periods of intromission and/or maintenance of intromission during the post-ejaculatory intervals, a multi-male mating system and large home range sizes and/or lower population density. Its size might also have helped females to choose from among the available males. -

The African Wild Cat, Felis Silvestris (Forster, 1780) and Synonym Felis Silvestris Cafra (Desmarest, 1822): an Overview
Chapter 1: General introduction CHAPTER 1 General introduction 1. The African wild cat, Felis silvestris (Forster, 1780) and synonym Felis silvestris cafra (Desmarest, 1822): an overview The African wild cat (Felis silvestris) has a wide distributional range (Fig. 1.1). However there is a paucity of information on all aspects of its biology. Since the wild cat is the ancestor of the domestic cat and they can interbreed and produce fertile offspring, hybridisation with the domestic form may be the biggest threat to the survival of wild cats today (Nowell & Jackson, 1996). 1.1 Phylogenetic relations and taxonomic classification Felid classification has a long and complex history fluctuating between extremes of “splitting” and “lumping” of the species (see historical review by Werdelin in Nowell & Jackson, 1996). Even on the subspecies level there has been considerable debate between the traditional taxonomic approach and the more contemporary approach using knowledge from population biology and genetics (Nowell & Jackson, 1996). The recent revolution in sequencing of genomes and new technologies to probe DNA has lead to the development of valuable new tools and methods for investigating phylogenetic relationships. Consequently, the first clearly resolved Feliday family tree has only recently been constructed (Johnson, Eizirik, Pecon-Slattery, Murphy, Antunes, Teeling & O’Brien, 2006, O’Brien & Johnson, 2007). The 37 felid species were grouped into eight lineages by molecular analysis, consistent with observations that lineages shared morphological, biological, physiological characteristics found only in their group. The recent findings suggest that all modern cats are descended from one of several Pseudaelurus species that lived in Asia around 11 million years ago (O’Brien & Johnson, 2007). -
Late–Early–Middle Pleistocene Records of Homotherium Fabrini (Felidae, Machairodontinae) from the Asian Territory of Russia
Abstracts 155 LATE–EARLY–MIDDLE PLEISTOCENE RECORDS OF HOMOTHERIUM FABRINI (FELIDAE, MACHAIRODONTINAE) FROM THE ASIAN TERRITORY OF RUSSIA Marina SOTNIKOVA. Geological Institute of Russian Academy of Sciences, Moscow, Russia. [email protected] Irina FORONOVA. Sobolev Institute of Geology and Mineralogy of SB RAS, Novosibirsk, Russia. [email protected] The time span of the Homotherium occurrence is defined within 3.7 to 0.5 Ma. In the Pliocene and Pleistocene the homotheres inhabited Eurasia, Africa, and North America. The latest homotheres are known as H. latidens from the terminal Early to Middle Pleistocene sediments in Europe from England to the Black Sea region (Turner, Antón, 1997; Sotnikova, Titov, 2009), whereas their synchronous analogs in Asia are described as H. ultimus in China and H. teilhardipiveteaui in Tajikistan (Teilhard de Chardin, 1939; Sharapov, 1989). In Asian Russia finds ofHomotherium were recorded in the Kuznetsk Depression (Novosergeevo quarry), near Krasnoyarsk (Kurtak archeological area), in the Adycha River basin, northern Siberia (Kyra-Sullar outcrop), and in the western Transbaikalia in the Zasukhino 2–3 and Kudun localities (Erbaeva et al., 1977; Sotnikova, 1978; Foronova, 1983, 2001). In the Novosergeevo quarry the lower mandible assigned to Homotherium aff. ultimus (IGG 3486) was collected nearby the section, in which the Sergeevo Formation deposits corresponding to the upper part of the Matuyama Chron are overlain by the Middle and Late Pleistocene sediments (Foronova, 1998, 2001). The finding of another lower mandible fragment of a small-sized Homotherium (IGG 1050) is associated with the Middle Pleistocene deposits of the Berezhekovo section in the Paleolithic Kurtak area (Foronova, 2001).
