New morphological information about Cretaceous sauropod dinosaurs from the Eromanga Basin,Queensland, Australia

New observations on various sauropod postcranial elements from Queensland provide insights into the taxonomic composition of northern Australia's sauropod fauna and the structure of sauropod vertebrae. An incomplete sauropod humerus from a site near Blackall, Queensland, represents the southernmost occurrence of sauropod fossils in the Eromanga Basin, and indicates a possibly new taxon. The internal architecture of at least one of the vertebral centra of Austrosaurus mckillopi comprises bony disks parallel to the posterior articular face and bony lamellae perpendicular to the anterior articular face reinforcing the structure against axial forces. The lack of pneumaticity proximally in dorsal ribs indicates that A. mckillopi may not be a titanosauriform. Material (QM F6737) from the Winton Formation includes probable osteoderms, the first known from Australian sauropods, and some of the oldest known. Comparison of this specimen with named Winton Formation sauropods suggests that it represents a distinct taxon.     

Traditional and computed tomographic (CT) techniques link modern and Cenozoic fruits of Pleiogynium (Anacardiaceae) from Australia

Computed tomography (CT) and traditional techniques were used to study the internal morphology of modern fruits of Pleiogynium timoriense (DC.) Leenh., and phosphatized and silicified fruits that were considered to belong to the genus. The results demonstrate that phosphatized fruits from the Oligocene–Miocene Dunsinane site at Riversleigh and silicified fruits from the Oligocene Glencoe Site, which are both in Queensland, are referable to Pleiogynium. The Riversleigh material (Pleiogynium wannanii Rozefelds, Dettmann & Clifford sp. nov.) is very similar to extant P. timoriense (DC.) Leenh. Both possess locules that, in the vertical axial plane, are asymmetrically reniform and enclosed by a two-layered endocarp, the inner layer woody and resistant to decay, the outer of fibres and parenchyma, surrounded by a mesocarp of fibres and sclereids and a parenchymatous exocarp. The outer mesocarp is sculpted by meridionally arranged, elongate depressions (germination apertures) situated at the dorsal surface of each locule; erosion of the mesocarp and outer endocarp provides passage for emergence of the embryo’s radicle on germination. The silicified material from Glencoe (P. parvum Rozefelds, Dettmann & Clifford sp. nov.) is smaller in all its parts and has locules that are ovate in the vertical axial plane. Discrete, cap-like, opercula are not evident in the fruit wall of the fossil and extant fruits studied. The presence of Pleiogynium, and associated taxa, indicates the existence of rainforest communities at Glencoe, and mixed open forest/rainforest at Riversleigh during Oligocene–Miocene times. The multilocular, fossil fruit described as Pleiogynium mitchellii Collinson, Manchester and Wilde from the Eocene deposits at Messel Quarry, Germany, is not considered to belong in the genus, as evidence of elongate depressions on the dorsal surface of the fruit stones has not been demonstrated conclusively, and its internal morphology/anatomy differs significantly from that of Pleiogynium.

Abstract

One of the few maps made by the indigenous population of the Americas and dating from the early eighteenth century to have survived, either in original or copied form, is the subject of this article. The map, on deerskin, was given to the new governor of South Carolina, Francis Nicholson, by an unknown Native American. Entitled A Map Describing the Situation of the Several Nations of Indians between South Carolina and the Massissipi River, it has generally been attributed to the Catawba nation. After situating the map in its historical period and detailing the claims for a Catawba origin, these claims are refuted and evidence supplied for a Cherokee origin.     

Remembering and forgetting 1974: the 2011 Brisbane floods and memories of an earlier disaster

The city of Brisbane, capital of the Australian state of Queensland, sits on a floodplain and has been struck by two devastating flood disasters in the last 50 years. This article contributes to the growing literature on disaster memory by tracing memories of a flood in 1974 as they were constructed and re‐enacted in a more recent disaster in 2011. The article examines how disaster memories shape local identities and considers how such memories influence policy and local knowledge, doing so by reference to an analysis of three forms of memory media—personal narratives, news media reporting, and built memorials. At times, memories of 1974 enabled Brisbane residents to prepare for an oncoming flood and to understand the scope of the 2011 event. Yet other memories produced a form of forgetting by positioning the earlier flood as a successfully navigated event now safely contained in the past. Findings from the analysis thus point to the importance of understanding memories of past disasters as a critical element of disaster planning and management.     

Recent Trends in Northwestern America

The Northwest Coast has long held a seminal role in the ethnographic and theoretical development of anthropology in North America. Both that role and the saliency of Native American Indigenous peoples have seemingly waned over time. Almost invisibly, however, a critical mass of new ethnographic perspectives and a new aspiration toward synthesis have emerged across the sub-disciplines and subject areas of Americanist anthropology in the United States and particularly in Canada. The Northwest Coast as the quintessential culture area has become a more fluid continuum of contact zones intersecting across Northeastern North America, as reflected in the works discussed here.     

ENCOUNTERING INDIGENEITY: RE-IMAGINING AND DECOLONIZING GEOGRAPHY

ABSTRACT. In an era of postcolonialism and postcolonization, Indigenous struggles continue. Within 'settler societies' issues of dispossession—particularly of lands—remain largely unresolved. As part of the discipline of geography's active movement away from its colonizing project, this introduction to this special edition of Geografiska Annaler B seeks to (re)focus a disciplinary lens, and (re)open a dialogue—and potential research trajectory - about 'indigenous geographies'. As the papers in this special issue demonstrate, new cultural geographies have begun a process of re-engagement with issues of indigeniety through careful, sensitive, inclusive, representative and emancipatory research projects.     

Standardization of long bone growth in children

Diaphyseal lengths of long bones of juveniles from five prehistoric Native American populations were collected in order to test the hypothesis of equivalence of relative lengths of all long bones. Results indicate that the relative lengths of all long bones are not equivalent and that the long bones of the Native Americans exhibit a consistent, significant sequence from relatively most affected (relatively smallest) to relatively least affected (relatively longest): femur, fibula, tibia, humerus, ulna and radius. This sequence can be explained if it is assumed that the most rapidly growing long bones are the most greatly affected by nutritional and disease stress.     

Brief encounters: Tatham Mound and the evidence for Spanish and Native American confrontation

Skeletal trauma often has been utilized to examine facets of inter- and intragroup violence. Eighteen skeletal elements from Tatham Mound are considered in this study, which exhibit wounds similar to documented cases of trauma caused by edged metal weapons. Tatham Mound is a sixteenth century mortuary site in central Gulf Coast Florida and is located within the reconstructed zone of contact with the Spanish explorer Hernando de Soto. Macroscopic and microscopic analyses of skeletal elements are conducted in order to distinguish trauma due to edged metal weapons from other perimortem and post-mortem bone modification. The damage on elements from Tatham Mound is compared with documented cases of trauma from edged metal weapons as well as medieval European skeletal remains exhibiting trauma due to edged metal weapons. It is concluded that some of the observed cases are probably due to metal weapon wounds inflicted by the Spanish explorers.     

Metallurgical analysis of copper artifacts from Cahokia

Copper artifacts from Cahokia Mounds, Illinois were analyzed from a materials science perspective to shed light on techniques used by Mississippian copper workers to deform nuggets of native copper into thin sheets. Eight small copper pieces from a copper-working site at Cahokia’s Mound 34 were subjected to metallographic examination. Replication experiments thereafter recreated features of the artifacts under controlled conditions. It is concluded that copper sheets were thinned through repeated cycles of hammering and annealing performed at temperatures achievable in an open wood fire. The welding of sheets to create multilayered objects was not observed in any artifacts and could not be accomplished experimentally. Additionally, a possible cutting method used on some artifacts was identified.     

Determining the Provenance of native copper artifacts from Northeastern North America: evidence from instrumental neutron activation analysis

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified.
