This reference provides comprehensive information on the taxonomy and distribution in time and space of all currently recognised southern African fossil mammals. After an introductory background chapter on southern Africa, mammals, sites and dating, the following chapters are presented by epoch, covering the Eocene, Miocene, Pliocene, Pleistocene and Holocene. Individual maps provide information on where in the landscape specific taxa have been found, and a comprehensive index lists all the fauna and site locations. It ends with a chapter on how the book can be used, and lines of future research. Collecting a vast amount of information together in an accessible format, this is an essential reference for non-specialist taxonomists and palaeontologists, as well as for those using fossil data for other applications, such as archaeology, neontology and nature conservation.

Probably the first published report of a fossil from South Africa was made in 1839 (Bain 1839; Seeley 1891), while T. H. Bowker excavated artefacts from near the mouth of the Fish River in 1857, and a Palaeolithic stone implement from Cape Town was sent to England in 1866 (Malan 1970). It was not until early in the twentieth century that palaeontological work began in earnest (e.g. Broom 1909a, 1909b and Péringuey 1911) published seminal works on the Stone Ages of South Africa. What might be described as the modern era began some 20 years later. South African mammalian palaeontology received a major boost with the report of Australopithecus africanus from Taung (Dart 1925), and by the second half of the 1930s Broom (e.g. 1936a, 1936b, 1937a, 1937b) had begun to describe material from the extremely rich limestone caves of the then Transvaal (now Gauteng), which continue to yield new forms (e.g. Berger et al. 2015; Fourvel 2018). The palaeontological importance of Namibia (then South West Africa) only began to be appreciated during the 1920s (e.g. Stromer 1921), but the importance of this country for Eocene and Miocene mammalian evolution has since become abundantly clear through the ongoing work of Martin Pickford and colleagues, especially Brigitte Senut, Jorge Morales and Pierre Mein.

    Late Quaternary environmental phases in the Eastern Cape and adjacent Plettenberg Bay-Knysna region and Little Karoo, South Africa Colin A. Lewis Department of Geography, Rhodes University, Grahamstown 6140, South Africa Tel: +27 46 6222416, Fax: +27 46 6361199 e-mail: [email protected] ABSTRACT Four major climato-environmental phases have been identified in the Eastern Cape, Plettenberg Bay-Knysna region and Little Karoo between somewhat before ~ 40 000 cal. a BP and the present: the Birnam Interstadial from before 40 000 cal. a BP until ~ 24 000 cal. a BP; the Bottelnek Stadial (apparently equating with the Last Glacial Maximum) from ~24 000 cal. a BP until before ~ 18 350 cal. a BP; the Aliwal North (apparently equating with the Late Glacial) from before ~ 18 350 cal. a BP until ~ 11 000 cal. a BP; the Dinorben (apparently equating with the Holocene) from ~ 11 000 cal. a BP until the present. The evidence for, and the characteristics of, these phases is briefly described. Key words Palaeoclimate. Southern Africa. Late Quaternary. Last Glacial Maximum. Late Glacial. Holocene. 1. Introduction 1.1. Purpose of this paper and use of proxy data The purpose of this paper is to summarise the evidence for, and describe the characteristics of, the major climato-environmental phases that have occurred in the Eastern Cape and adjacent Plettenberg Bay-Knysna region and Little Karoo during the last ~ 40 000 a (Fig. 1). The age of these phases has been established mainly by radiocarbon dating. Events predating ~ 40 000 cal. a BP are effectively beyond the range of radiocarbon dating and are not considered in this paper.

  • No Evidence for Proteolytic Venom Resistance in Southern African Ground Squirrels
    1 No evidence for proteolytic venom resistance in southern African ground squirrels Molly A. Phillips, Jane M. Waterman, Pg Du Plessis, Martin Smit, and Nigel C. Bennett Abstract Many species that interact with venomous snakes show resistances to their venoms. The family Sciuridae has several North American members that harass venomous snakes and show proteolytic resistances in their sera. We examined sera collected from an African ground squirrel (Xerus inauris) against two sympatric venomous snakes (Bitis arietans and Naja annulifera) and found no support for proteolytic resistance. Our results add to our understanding of the risks in predator defense within the family Sciuridae. Keywords: Xerus inauris; Bitis arietans; Naja annulifera; Venom; Venom resistance; Predator-prey Animal venoms are a complex mixture of proteins and peptides that induce many destructive physiological effects for a variety of purposes, including prey capture (Fry et al., 2008; Jansa and Voss, 2011), digestion (Thomas and Pough, 1979), and defense (Kardong, 1982). The evolution of venom in snakes is thought to be a major factor leading to the radiation of over 2500 advanced snake species (Vidal, 2002). Some animals that interact with venomous snakes have physiological resistance to venom. As a predator, the Indian grey mongoose (Herpestes edwardsii) is resistant to the haemorrhagic effects caused by the venom of many snake species (Tomihara et al., 1990). California ground squirrels (Spermophilus (Otospermophilus) beecheyi) defend against snake predation by mobbing and have resistance against the proteolytic activity of the venom from northern Pacific rattlesnakes (Crotalus oreganus) (Biardi, 2000). The Cape ground squirrel (Xerus inauris) is a ground-dwelling sciurid that inhabits the arid regions of southern Africa (Skurski and Waterman, 2005).

  • 29 Figure8. the Limited Rank Hydrophilic Sedge and Grass Patches Within the Central Valley Bottom Wetland Provide Suitable Roost
    Figure8. The limited rank hydrophilic sedge and grass patches within the central valley bottom wetland provide suitable roosting and foraging habitat for African Grass Owls. The high levels of human disturbances on the site including hunting with dogs; severely restricts the likelihood of any nests and limits potential roosting suitability. The annual burning of the site restricts the vegetative cover along the valley bottom wetland. Off-road bikes, quads and vehicle tracks transverse the entire site as well as helicopter training and landing on the site and open areas to the south of the site adjacent to the Waterval cemetery. African Grass Owls are found exclusively in rank grass, typically, although not only, at fair altitudes. Grass Owls are secretive and nomadic breeding in permanent and seasonal vleis, which it vacates while hunting or post-breeding, although it will breed in any area of long grass and it is not necessarily associated with wetlands. It marshlands it is usually outnumbered by the more common Marsh Owl (Asio capensis) 10:1 (Tarboton et al. 1987). Grass Owls nest on the ground within a system of tunnels constructed in mostly tall grass; peak-breeding activity (February- April) tends to coincide with maximum grass cover (Steyn 1982). Grass Owls specialise in large rodent prey, particularly Otomys vlei rats, although a wide range of rodent prey species, including Rhabdomys, Praomys, Mus, and Suncus, are taken (Earle 1978). Some local and nomadic movements in response to fluctuating food supplies, fire and the availability of suitable habitat can be expected (Steyn 1982). The ecological requirements of this species make it susceptible to many land-use changes impacting contemporary South Africa.

Blumenschine and approved by ______________________________ ______________________________ ______________________________ ______________________________ New Brunswick, New Jersey January 2007 ABSTRACT OF THE DISSERTATION HOMININ-CARNIVORE INTERACTIONS: EVIDENCE FROM MODERN CARNIVORE BONE MODIFICATION AND EARLY PLEISTOCENE ARCHAEOFAUNAS (KOOBI FORA, KENYA; OLDUVAI GORGE, TANZANIA) by Briana Lee Pobiner Dissertation Director: Robert J. 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.

    A PALAEOECOLOGICAL AND TAPHONOMIC ANALYSIS OF THE MICROMAMMALS FROM A MARINE ISOTOPE STAGE 5 LAYER AT KLASIES RIVER, SOUTHERN CAPE, SOUTH AFRICA. By: Nompumelelo Maringa 717230 Supervisor: Prof Sarah Wurz Co-Supervisor: Dr Jerome Reynard A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, 2020, in fulfilment of the requirements for the degree of Master of Science. DIVISION OF ARCHAEOLOGY SCHOOL OF GEOGRAPHY, ARCHAEOLOGY AND ENVIRONMENTAL STUDIES. Declaration I declare that this dissertation is my own, unaided work. It is being submitted for the Degree of Master of Science in the University of the Witwatersrand, Johannesburg. It has not been submitted before for any degree or examination at any other University. Name: Nompumelelo Maringa Student number: 717230 Date: 6 July 2020 Signature: i Abstract This research investigated the palaeoecology at Klasies River main site during Marine Isotope Stage 5d by analysing the micromammal remains excavated from the BOS Three layer in Cave 1 during the 2017 excavation season. During this time, Cave 1 was inhabited by anatomically modern humans with complex modern behaviour. The taphonomic analysis shows that light and moderate digestion on the cranials and post-cranials are common, with the majority of specimens displaying moderate breakage. These modifications are associated with Tyto alba (Barn owl) and Bubo africanus (Spotted eagle-owl) as the accumulators of the assemblage. Encrustation and soil staining are the most prevalent post-depositional modifications in both cranial and post-cranial assemblages. This relates to the presence of tufa, speleothem material and the presence of water. The taxonomic analysis on the cranial elements (mandibles, maxillae and teeth) identified the most prominent species as Otomys irroratus (Southern African vlei rat), Myosorex varius (Forest shrew) and Crocidura flavescens (Greater red musk shrew).

ALLEN A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 1997 Copyright 1997 by Craig R. Allen ACKNOWLEDGEMENTS The work presented in this dissertation would not have been possible without the cooperation and encouragement of many. Foremost is the understanding of my immediate family, that is my wife Patty and now three-year-old son, Reece. Reece, while generally confused about what I was doing, nonetheless supported my effort to "write a book" in order to become a "doctor." Conflicts arose only when he needed my computer for dinosaur games. My co-advisors, W. M. Kitchens and C. S. Holling, encouraged my investigations and provided me with intellectual support and opportunity. For the same reasons, I extend my appreciation to my committee members, S. Humphrey, M. Moulton and D. Wojcik. Numerous friends and colleagues provided me with intellectual support and acted as a sounding board for ideas. Foremost are E. A. Forys, G. Peterson M. P. Moulton and J. Sendzemir as well as the entire "gang" of the Arthur Marshal Ecology Laboratory. I wish to thank all for their support and friendship. II!

ABSTRACT Our understanding of p-globin gene cluster evolutionlwithin eutherian mammals .is based solely upon data collected from species in the two most derived eutherian superorders, Laurasiatheria and Euarchontoglires. Ifence, nothing is known regarding_the gene composition and evolution of this cluster within afrotherian (elephants, sea cows, hyraxes, aardvarks, elephant shrews, tenrecs and golden moles) and xenarthran (sloths, anteaters and armadillos) mammals.
