Megafauna and Methods New Approaches to the Study of Megafaunal Extinctions Megafauna and Methods New Approaches to the Study of Megafaunal Extinctions Organized by Jillian Swift and Patrick Roberts Max Planck Institute for the Science of Human History Jena, Germany 20-21 February, 2017 The extinction of large-bodied animals (often termed ‘megafauna’) during the Late Pleistocene and Holocene has been described as one of the most significant events in recent Earth history. While climate change, disease, and even extraterrestrial impacts have been postulated as significant contributors, the potential role of our species in this process has proved of significant interest, particularly in addressing the impacts of Homo sapiens on the world’s ecosystems following its expansion beyond Africa. Teasing apart natural and human impacts on large fauna has proven highly challenging, and requires both regional and global approaches, as well as a broad suite of scientific methods. In this workshop we seek to examine how megafaunal extinctions are studied, and explore how new methods in such fields as ancient DNA research, proteomics, ZooMS, palaeoecology and computational modeling might be combined with large- scale interdisciplinary efforts that bring together researchers from different projects, regions and/or disciplines. The aim is develop a novel, multi-proxy, collaborative research project aimed at improving the narratives and scope of megafaunal studies. Our hope is that this will help to test ideas regarding the timing and nature of lasting human impacts on the world’s ecosystems. Format: Speakers are asked to focus on how new methods and approaches and how these might be leveraged to generate a novel approach to the topic of megafaunal extinctions. Our goal is to have as much discussion and interaction as possible. Please keep talks to a maximum of 15 minutes, allowing at least 5 minutes for questions after each presentation. 1 DAY 1 Monday, 20 February 8:00-8:30 Arrival and coffee at Max Planck Institute for the Science of Human History SESSION 1: New Approaches to Megafaunal Extinctions and the Max Planck Institute for the Science of Human History 8:30-8:40 Nicole Boivin (Max Planck Institute for the Science of Human History) Welcome 8:40-8:55 Jillian Swift (Max Planck Institute for the Science of Human History) Megafauna and Methods: Laying the groundwork for innovative approaches to megafaunal extinctions 8:55-9:10 Michael Petraglia (Max Planck Institute for the Science of Human History) Did humans shape environments in the Pleistocene? 9:10-9:30 Initial thoughts from workshop participants SESSION 2: New Molecular Techniques for Taxonomic Identifications Chair: Christopher Johnson (University of Tasmania) 9:30-9:45 Frido Welker (Max Planck Institute for Evolutionary Anthropology) The potential of ancient protein research to rhinoceros extinction events 9:50-10:05 Viviane Slon (Max Planck Institute for Evolutionary Anthropology) Recovering mammalian mitochondrial DNA from Late and Middle Pleistocene sediments by hybridization capture 10:10-10:25 Michael Bunce (Curtin University) Scrapheap Challenge: Insights gained from analyzing ancient DNA preserved in bulk bone 10:30-11:00 Discussion What is the potential for these analyses to bring new light to preexisting sites/assemblages?

Abstract Since the frst discoveries of megafauna fossils in the Wellington Valley of New South Wales in the 1830s, caves have featured prominently in the study of Quaternary Australia. Today, most of the well-dated, strati- fed Quaternary megafauna sites are known from caves. Tis refects the relatively stable preservation environment within Australian caves, where skeletal remains may lay undisturbed for hundreds of thousands of years.

In contrast, the equine fossil record shows that an extraordinarily richer diversity existed in the past and provides multiple examples of a highly dynamic evolution punctuated by several waves of explosive radiations and extinctions, cross-continental migrations, and local adaptations.

    Archaeology Resources Page Intentionally Left Blank Archaeological Resources Background Archaeological Resources are defined as “any prehistoric or historic district, site, building, structure, or object [including shipwrecks]…Such term includes artifacts, records, and remains which are related to such a district, site, building, structure, or object” (National Historic Preservation Act, Sec. 301 (5) as amended, 16 USC 470w(5)). Archaeological resources are either historic or prehistoric and generally include properties that are 50 years old or older and are any of the following: • Associated with events that have made a significant contribution to the broad patterns of our history • Associated with the lives of persons significant in the past • Embody the distinctive characteristics of a type, period, or method of construction • Represent the work of a master • Possess high artistic values • Present a significant and distinguishable entity whose components may lack individual distinction • Have yielded, or may be likely to yield, information important in history These resources represent the material culture of past generations of a region’s prehistoric and historic inhabitants, and are basic to our understanding of the knowledge, beliefs, art, customs, property systems, and other aspects of the nonmaterial culture. Further, they are subject to National Historic Preservation Act (NHPA) review if they are historic properties, meaning those that are on, or eligible for placement on, the National Register of Historic Places (NRHP). These sites are referred to as historic properties. Section 106 requires agencies to make a reasonable and good faith efforts to identify historic properties. Archaeological resources may be found in the Proposed Project Area both offshore and onshore.

  • The Giant Alcelaphine Antelope, M. Priscus, Is One of Six Extinct Species
    Palaeont. afr. , 32, 17-22 (1995) A NEW FIND OF MEGALOTRAGUS PRISCUS (ALCELAPHINI, BOVIDAE) FROM THE CENTRAL KAROO, SOUTH AFRICA by J.S. Brink!, H. de Bruiyn2, L.B. Rademeyer2 and W.A. van der Westhuizen2 lFlorisbad Quaternary Research Dept., National Museum, POBox 266, Bloemfontein 9300, South Africa 2Dept. of Geology, University of the Orange Free State, Bloemfontein 9300, South Africa ABSTRACT We document the occurrence of the Florisian, or late Quaternary, form of the giant a1celaphine, Megalotragus priscus, from dongas on the Ongers River, near Britstown in the central Karoo. This is significant as it confirms the occurrence of the species in the Karoo and it suggests significantly wetter environments and productive grasslands in the central Karoo in pre-Holocene times. The present-day Karoo environment did not maintain populations of large ruminant grazers similar to M. priscus, and other specialized Florisian grazers, prior to the advent of agriculture and pasture management. Aridification in recent times is the likely cause of changes in grassland quality and the local dissappearance of these animals, if not their extinction. KEY WORDS: A1celaphine evolution, Florisian mammals, Late Pleistocene extinction INTRODUCTION modem bovid fauna is the product (Vrba 1976, 1979; The giant alcelaphine antelope, M. priscus, is one of Bigalke 1978; Gentry 1978; Gentry & Gentry 1978). six extinct species which define the Florisian Land One example of this increase in end~mism is the Mammal Age (Brink 1994; Hendey 1974). The evolution of M. priscus. An ancestral form, species is known from a variety of late Quaternary M. katwinkeli, is known from East Africa and possibly sites in the interior of southern Africa as well as from some southern African Plio-Pleistocene sites, but in the Cape Ecozone in pre-Holocene times (Brink 1987; the Middle and Late Pleistocene the genus Bender & Brink 1992; Klein 1980, 1984; Klein & Megalotragus is only found in southern African fossil Cruz-Uribe 1991).
