Human occupation of northern Australia by 65,000 years ago

The time of arrival of people in Australia is an unresolved question. It is relevant to debates about when modern humans first dispersed out of Africa and when their descendants incorporated genetic material from Neanderthals, Denisovans and possibly other hominins. Humans have also been implicated in the extinction of Australia’s megafauna. Here we report the results of new excavations conducted at Madjedbebe, a rock shelter in northern Australia. Artefacts in primary depositional context are concentrated in three dense bands, with the stratigraphic integrity of the deposit demonstrated by artefact refits and by optical dating and other analyses of the sediments. Human occupation began around 65,000 years ago, with a distinctive stone tool assemblage including grinding stones, ground ochres, reflective additives and ground-edge hatchet heads. This evidence sets a new minimum age for the arrival of humans in Australia, the dispersal of modern humans out of Africa, and the subsequent interactions of modern humans with Neanderthals and Denisovans.

The archaeology, chronology and stratigraphy of Madjedbebe (Malakunanja II): A site in northern Australia with early occupation.

Published ages of >50 ka for occupation at Madjedbebe (Malakunanja II) in Australias north have kept the site prominent in discussions about the colonisation of Sahul. The site also contains one of the largest stone artefact assemblages in Sahul for this early period. However, the stone artefacts and other important archaeological components of the site have never been described in detail, leading to persistent doubts about its stratigraphic integrity. We report on our analysis of the stone artefacts and faunal and other materials recovered during the 1989 excavations, as well as the stratigraphy and depositional history recorded by the original excavators. We demonstrate that the technology and raw materials of the early assemblage are distinctive from those in the overlying layers. Silcrete and quartzite artefacts are common in the early assemblage, which also includes edge-ground axe fragments and ground haematite. The lower flaked stone assemblage is distinctive, comprising a mix of long convergent flakes, some radial flakes with faceted platforms, and many small thin silcrete flakes that we interpret as thinning flakes. Residue and use-wear analysis indicate occasional grinding of haematite and woodworking, as well as frequent abrading of platform edges on thinning flakes. We conclude that previous claims of extensive displacement of artefacts and post-depositional disturbance may have been overstated. The stone artefacts and stratigraphic details support previous claims for human occupation 50-60 ka and show that human occupation during this time differed from later periods. We discuss the implications of these new data for understanding the first human colonisation of Sahul.

Review Of Geophysical Applications in Australian archaeology

Abstract Multidisciplinary approaches are now commonplace in the investigation of archaeological sites worldwide. Consequently, geophysics has become an increasingly important tool for reconstructing past landscapes and investigating research questions. However, despite their acceptance internationally, in Australia the use of geophysical techniques on archaeological sites has been underutilised. This paper examines the history of archaeological geophysics in Australia and seeks to understand, given their potential advantages, the role that factors such as costs, time, instrument availability and lack of theoretical knowledge have played in the underrepresentation of these methods in local archaeological investigations to date. With the recent introduction of short courses in archaeological geophysics to at least one Australian tertiary institution, this review is a timely overview of where this discipline has been, what it has to offer and whether there is potential for Australian archaeologists to develop the skills necessary to conduct archaeological geophysic investigations, as their international counterparts do already, in the future.

The Queensland Native Police and strategies of recruitment on the Queensland Frontier, 1849-1901

ABSTRACT Although historians have provided substantial insights into the structure, development and activities of the Queensland Native Mounted Police, they have rarely focused on the complex and sensitive issue of Aboriginal recruitment. A careful reading of historical records, however, identifies several methods, including coercion, intimidation, kidnapping and inducement, as well as “voluntary” enlistment. It is difficult to identify Aboriginal agency in recruitment processes as the records are entirely one-sided—the voices of the troopers themselves are absent from the archival sources. In this article, we examine the cultural and historical contexts of Aboriginal recruitment—for example, the dire social situations of Aboriginal survivors of the frontier war and the absence of future survival options for the potential recruits. We explore, through the framework of historical trauma, the impacts on vulnerable victims of violence and other devastating effects of colonisation. We conclude that the recruitment of Aboriginal troopers was far from a homogeneous or transparent process and that the concept of agency with regard to those who can be considered war victims themselves is extremely complex. Unravelling the diverse, conflicting and often controversial meanings of this particular colonial activity remains a challenge to the historical process.

Archaeological geophysical survey of a Prehistoric Bronze Age site in Cyprus (Alambra Mouttes)—applications and limitations

The University of Queensland Alambra Archaeological Mission (UQAAM) conducted a program of geophysical survey and archaeological excavation over four seasons from 2012 to 2016. This program has allowed this study to compile a large array of geophysical data, which has been tested against actual excavation results. By integrating the two forms of archaeological investigation, the UQAAM has been able to identify geophysical ‘signatures’ diagnostic and indicative of internal architectural features relating to the Cypriot Prehistoric Bronze Age (c2400–1750BC). This is the first time internal features have been identified using these techniques on a Middle Bronze Age site in Cyprus. The program has also identified two, and possibly four, areas of domestic settlement. This has yielded results that are of considerable value to cultural heritage managers of the site, which is experiencing development pressures. While identifying several constraints with the geophysical survey for the Prehistoric Bronze Age in Cyprus, the program has demonstrated the efficacy of a combined geophysical survey and excavation approach to sites of the Early-Middle Bronze Age period.

The homestead as fortress: Fact or folklore?

Houses are quintessential statements of identity, encoding elements of personal and social attitudes, aspirations and realities. As functional containers for human life, they reflect the exigencies of their construction and occupation, as well as the alterations that ensued as contexts, occupants and uses changed. As older houses endure into subsequent social contexts, they become drawn into later symbolic landscapes, connoting both past and present social relationships simultaneously and connecting the two via the many ways they are understood and represented in the present. As historical archaeologist Anne Yentsch has argued: ‘Many cultural values, including ideas about power relationships and social inequality, are expressed within the context of the stories surrounding houses’.1 This paper is one attempt to investigate the stories surrounding a ruined pastoral homestead in central northern Queensland in light of relationships between non-Aboriginal and Aboriginal people on the frontier.

A multi-proxy study of anthropogenic sedimentation and human occupation of Gledswood Shelter 1: exploring an interior sandstone rockshelter in Northern Australia

Rockshelters contain some of the most important archives of human activity in Australia but most research has focused on artifacts and cultural context. This study explores geomorphological and geoarchaeological approaches for understanding a sandstone rockshelter in interior northern Australia: Gledswood Shelter 1. At this site, magnetic susceptibility and micromorphology techniques were integrated with bulk sedimentology, soil chemistry and geochronology to better understand the record of human impact and site formation processes. The micromorphology studies indicate that primary depositional fabrics, such as graded bedding or laminations, are absent, and sediment structural development is low throughout the entire sequence, with most samples exhibiting a high degree of post-depositional mixing. The sediment magnetic susceptibility analysis reveals magnetic changes coinciding with human occupation, a result of anthropogenic burning. Specifically we highlight that combustion features are prevalent in this sandstone shelter and provide critical insights into the human usage of the shelter.

Understanding Australia’s cultural history through archaeological geophysics

The aim of this thesis is to develop and apply geophysical methods for Australian archaeology. The methods focus on magnetic susceptibility and ground penetrating radar (GPR). The techniques are contextualised through application to the following four key archaeological questions: 1) Can magnetic susceptibility assist in resolving questions surrounding the potential downward movement of stone artefacts in rockshelter deposits?; 2) Is human occupation persistent through the changing climatic regime associated with the last glacial maximum (LGM) at a Pleistocene-aged rockshelter in interior Australia?; 3) How might we identify burials in a geologically complex rockshelter deposit? and; 4) How might magnetic susceptibility contribute to knowledge about the formation of ‘archaeologically instantaneous’ shell matrix sites? In exploring these questions, research was conducted at two rockshelters in northern Australia and on three shell mounds in the Gulf of Carpentaria, Australia. The results demonstrate that both magnetic susceptibility and GPR studies can be valuable tools in deciphering key archaeological questions in the Australian landscape. The most important findings relate to the ability of magnetic susceptibility signals to clearly define levels at which humans first appear in the archaeological record. This will allow major progress in determining the timing and dispersion of human settlements for Australian sites.
