Lucy in the Sky with Diamonds and Butterflies
Home / Life / Specials Lucy in the sky with diamonds and butterflies A butterfly flapping its wings in Brazil can produce a tornado in Texas. The author of this poetic image was Edward Lorenz, a meteorologist who in 1972 explained how small changes in a system as complex as the atmosphere can generate large effects. This expression was a huge success and since then has often been used. Two million years ago, in the middle of the Pleistocene, a population of African apes lived astride the border between two worlds: the old world of the forest and the new world of the grasslands. They were Australopithechi, “southern apes”, which had recently climbed down from the trees but were already able to walk as bipeds, just in a way that was a little more ungainly than we do. They had their feet on the ground but their paws still on branches because trees remained a safe refuge into which they could climb to rest and to escape the large felines of the time, huge and ferocious beasts like the sabre-toothed cat ( Homotherium crenatidens ), the Megantereon, cousin of the sabre-toothed tiger and the worst of all of them: the Dinofelis, literally meaning “terrible cat”. It seems that the incisions found on the fossilised bones of some Australopitechi were the result of attacks by that prehistoric leopard. The most famous Australopitecus is Lucy, a young female who lived just over three million years ago, discovered in Ethiopia in November 1974.

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.

Carnivora, Mammalia) in the Blancan of North America
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.

Blumenschine Interactions between Oldowan hominins and larger carnivores likely shaped important aspects of hominin adaptation including morphology, foraging patterns, habitat preferences, and social behavior. Hypotheses of Oldowan hominin carcass procurement strategies include scavenging large muscle masses, flesh scraps and/or bone marrow from larger felid kills. Efforts to evaluate these hypotheses are hindered by a current inability to recognize zooarchaeologically the specific carnivore taxa with which hominins interacted. This dissertation helps redress this limitation by documenting and quantifying taxon-specific traces of modern African carnivore consumption of Thomson’s gazelle through buffalo-sized prey carcasses, including gross bone damage patterns, the incidence and patterning of tooth marking, and tooth mark measurements. Integrating these taphonomic traces facilitates the construction of hypotheses concerning the ii involvement of particular carnivores with Oldowan hominins. These results are applied to four Plio-Pleistocene archaeofaunas from East Africa to test hypotheses of hominin- carnivore interaction and document hominin carcass procurement strategies. -
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.

Pleistocene Panthera Leo Spelaea
Quaternaire, 22, (2), 2011, p. 105-127 PLEISTOCENE PANTHERA LEO SPELAEA (GOLDFUSS 1810) REMAINS FROM THE BALVE CAVE (NW GERMANY) – A CAVE BEAR, HYENA DEN AND MIDDLE PALAEOLITHIC HUMAN CAVE – AND REVIEW OF THE SAUERLAND KARST LION CAVE SITES n Cajus G. DIEDRICH 1 ABSTRACT Pleistocene remains of Panthera leo spelaea (Goldfuss 1810) from Balve Cave (Sauerland Karst, NW-Germany), one of the most famous Middle Palaeolithic Neandertalian cave sites in Europe, and also a hyena and cave bear den, belong to the most im- portant felid sites of the Sauerland Karst. The stratigraphy, macrofaunal assemblages and Palaeolithic stone artefacts range from the final Saalian (late Middle Pleistocene, Acheulean) over the Middle Palaeolithic (Micoquian/Mousterian), and to the final Palaeolithic (Magdalénien) of the Weichselian (Upper Pleistocene). Most lion bones from Balve Cave can be identified as early to middle Upper Pleistocene in age. From this cave, a relatively large amount of hyena remains, and many chewed, and punctured herbivorous and carnivorous bones, especially those of woolly rhinoceros, indicate periodic den use of Crocuta crocuta spelaea. In addition to those of the Balve Cave, nearly all lion remains in the Sauerland Karst caves were found in hyena den bone assemblages, except those described here material from the Keppler Cave cave bear den. Late Pleistocene spotted hyenas imported most probably Panthera leo spelaea body parts, or scavenged on lion carcasses in caves, a suggestion which is supported by comparisons with other cave sites in the Sauerland Karst. The complex taphonomic situation of lion remains in hyena den bone assemblages and cave bear dens seem to have resulted from antagonistic hyena-lion conflicts and cave bear hunting by lions in caves, in which all cases lions may sometimes have been killed and finally consumed by hyenas. -
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. -

Late Pleistocene Panthera Leo Spelaea (Goldfuss, 1810) Skeletons
Late Pleistocene Panthera leo spelaea (Goldfuss, 1810) skeletons from the Czech Republic (central Europe); their pathological cranial features and injuries resulting from intraspecific fights, conflicts with hyenas, and attacks on cave bears CAJUS G. DIEDRICH The world’s first mounted “skeletons” of the Late Pleistocene Panthera leo spelaea (Goldfuss, 1810) from the Sloup Cave hyena and cave bear den in the Moravian Karst (Czech Republic, central Europe) are compilations that have used bones from several different individuals. These skeletons are described and compared with the most complete known skeleton in Europe from a single individual, a lioness skeleton from the hyena den site at the Srbsko Chlum-Komín Cave in the Bohemian Karst (Czech Republic). Pathological features such as rib fractures and brain-case damage in these specimens, and also in other skulls from the Zoolithen Cave (Germany) that were used for comparison, are indicative of intraspecific fights, fights with Ice Age spotted hyenas, and possibly also of fights with cave bears. In contrast, other skulls from the Perick and Zoolithen caves in Germany and the Urșilor Cave in Romania exhibit post mortem damage in the form of bites and fractures probably caused either by hyena scavenging or by lion cannibalism. In the Srbsko Chlum-Komín Cave a young and brain-damaged lioness appears to have died (or possibly been killed by hyenas) within the hyena prey-storage den. In the cave bear dominated bone-rich Sloup and Zoolithen caves of central Europe it appears that lions may have actively hunted cave bears, mainly during their hibernation. Bears may have occasionally injured or even killed predating lions, but in contrast to hyenas, the bears were herbivorous and so did not feed on the lion car- casses.
