Ethnohistoric accounts indicate that the people of Australia's Channel Country engaged in activities rarely recorded elsewhere on the continent, including food storage, aquaculture and possible cultivation, yet there has been little archaeological fieldwork to verily these accounts. Here, the authors report on a collaborative research project initiated by the Mithaka people addressing this lack of archaeological investigation. The results show that Mithaka Country has a substantial and diverse archaeological record, including numerous large stone quarries, multiple ritual structures and substantial dwellings. Our archaeological research revealed unknown aspects, such as the scale of Mithaka quarrying, which could stimulate re-evaluation of Aboriginal socio-economic systems in parts of ancient Australia. Keywords: Australia, Aboriginal, Mithaka, trade networks, cultivation, villages, stone extraction, Introduction In this article, we report the first results of an ongoing archaeological project in the traditional territory of the Mithaka people, in Australia's Channel Country (Figure 1).

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 Australias 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., Author(s): Chris Clarkson (corresponding author) [1]; Zenobia Jacobs (corresponding author) [2, 3]; Ben Marwick [3, 4]; Richard Fullagar [3]; Lynley Wallis [5]; Mike Smith [6]; Richard G.

This paper presents preliminary results from the 2019 excavations at Walufeni Cave, at the eastern end of the Great Papuan Plateau (GPP) in western Papua New Guinea. Preliminary dating and analysis of the unfinished excavations at Walufeni Cave span the Holocene and probably continue into the Late Pleistocene, confirming the presence of people on the Plateau from at least the Early Holocene and potentially much earlier. The data presented here offer a site-specific model of early intensive site use from at least 10,000 years ago, then ephemeral use, followed by a sustained Late Holocene occupation. Although there are significant changes in the quantity of material discard over time, there is little evidence for significant change in the subsistence base or technology, reflecting a degree of relative homogeneity until the Late Holocene, when we see the introduction of pig, a change of focus in the plant economy and the presence of marine shell from the southern coast.

This study presents the first data on a level one archaeology student cohort, exploring their demographic composition and motivations for enrolling, as well as external stressors such as health and caring responsibilities that may influence student study goals, retention, and needs. A survey of 107 students enrolled in introductory level archaeology units at 13 Australian universities was undertaken in Semester 1, 2021. The results show a diverse cohort by age, gender, and educational background. Consistent with the professional Australian archaeological community, there is little diversity in the ethnicity of enrolled students. Further, many respondents reported having caring responsibilities, and both physical and mental health concerns. Students were motivated to enrol both for general interest and future career pathways; however, there was a poor understanding within the cohort of Australian archaeological job opportunities. These results indicate that there is clearly much to be done in public archaeological engagement and outreach in Australia. What is required of the Australian archaeological community is a concerted effort to improve how the discipline is taught and learned across all levels of education, and a collaborative approach to designing teaching methods suitable for our modern student cohort.

We review current zooarchaeological practice in Australia, identifying major research themes and key methodological gaps where opportunities exist for the development of Australian zooarchaeology as a discipline. We demonstrate that marsupial remains form a significant component of Australian zooarchaeological assemblages, yet high resolution taxonomic identification of these remains continues to prove challenging, owing to a combination of high species diversity and few resources which provide diagnostic criteria for discriminating morphologically similar, but ecologically variable taxa. The lack of robust protocols for discriminating marsupial taxa significantly impacts our ability to effectively integrate zooarchaeological data into broader narratives of Aboriginal colonisation, resilience and adaptation across Australia. Publication of identification protocols would help refine and standardise diagnostic criteria used between analysts, improve the methodological transparency of zooarchaeological analysis and provide resources for the training of a new generation of specialists. A range of opportunities currently exist, utilising qualitative and quantitative techniques, to significantly contribute towards the methodological robustness of zooarchaeological practice in Australia.

Ethnographic records show that people from Orokolo Bay in the Papuan Gulf (Papua New Guinea) made, used, and exchanged artefacts made from bone and teeth during the twentieth century. Archaeologically, these kinds of artefacts are poorly documented, partly because osseous materials tend to decay rapidly in exposed tropical rainforest sites. Where these artefacts have been found in the Papuan Gulf, only a few have been reported in detail. Here we contribute detailed analyses of eight osseous artefacts from the past village site of Popo which date to within the period 770–220 cal BP. We describe a modified shark tooth, a drilled or pierced dog tooth ornament, several bone points, and a trapezoidal section of modified bone. An ochred bone point shows that people applied pigment to material culture in the period 540–285 cal BP; the item is the only known archaeological evidence for pigment use on bone in the Papuan Gulf. Our analyses provide a starting point for historicising the use of osseous artefacts in this part of the Papuan Gulf. [ABSTRACT FROM AUTHOR]

Stable isotopic analysis of palaeontological and archaeological biogenic apatite carbonates from herbivorous mammalian species represents an important tool for worldwide palaeoecological research. Tooth enamel carbonates are more resistant to taphonomic processes than bone or dentine carbonates but are not invulnerable to diagenesis. As such, they require careful preanalytical processing that considers depositional environment and age. An established part of this process includes a weak acid treatment to remove soluble exogenous carbonates; however, published treatment times for isotopic studies of archaeological tooth enamel are variable and range from 15 min to over 8 hr. This study tests three different pretreatment protocols on modern and Pleistocene age archaeological kangaroo teeth (dating from contemporary to 46,000 bp) to assess the effect of acid treatment time on isotopic integrity. The results indicate that treatment time is a critical parameter for producing consistency across results and shorter pretreatments of 4 hr or less are preferable for removing diagenetic carbonates while minimising alteration of the biological signal.

Located on the edge of Australia's North West continental shelf, Barrow Island is uniquely located to address a number of research questions, such as the antiquity and changing nature of Indigenous occupation, including shifting uses of regional economic resources in response to post-glacial sea-level rise. These questions are addressed from a range of archaeological, zooarchaeological, and geoarchaeological disciplines. Although only preliminary, results to date indicate the presence of marine resources dating to before sea-level stabilization (∼ 7.5 ka) that contain both dietary and utilitarian species, including high-ranked species such as sea turtle. The marine assemblages reflect a variety of habitats and substrates with a 17,000-year record for the presence of a former tidal marsh or estuary. We also note recently obtained14C and OSL dates that extend the dietary marine faunas and initial occupation to well before 41 ka. This demonstrates that consumption of coastal resources began prior to the Holocene, when we begin to observe more widespread evidence of marine resource exploitation in the broader Canarvon Bioregion of northwest Australia. This evidence supports arguments for further research to directly test both the productivity of, and human reliance on, marine habitats from initial occupation. [ABSTRACT FROM AUTHOR]

In regions that lack built structures or stratified open archaeological sites, such as precolonial Australia, rockshelters are a major source of detailed information for understanding the nature and timing of human occupation. A key concern is that the proposed ages for the earliest archaeological sites are based on luminescence dating of sediments, rather than directly of cultural materials, leaving the association between the sediments and evidence of human activity questionable. Here, we present evidence of magnetic enhancement associated with cultural horizons within the deposits of a Pleistocene rockshelter in interior northern Queensland. Soil magnetic studies combined with experimental burning show that magnetically enhanced sediments in Gledswood Shelter 1 are the result of anthropogenic burning of hearth fires, which burn hotter and for a longer time than natural wild fires. These techniques appear to work in this setting because of the nature of the local geology and the geological antiquity of the landscape. Susceptibility and frequency dependence of susceptibility signatures provide a critical tool to resolve that human occupation starts at 2.2 m depth within a stratigraphic section. In conjunction with luminescence dating, soil magnetic studies provide an opportunity for archaeologists to resolve the timing of human settlement in Australia and other intracratonic plate settings.

This paper presents the first application of mammal tooth enamel carbonate stable isotope analysis for the purpose of investigating late Pleistocene–early Holocene environmental change in an Australian archaeological context. Stable carbon (δ13C) and oxygen (δ18O) isotope ratios were analyzed from archaeological and modern spectacled hare wallaby (Lagorchestes conspicillatus) and hill kangaroo (Osphranter robustus) tooth enamel carbonates from Boodie Cave on Barrow Island in Western Australia. δ18O results track the dynamic paleoecological history at Boodie Cave including a clear shift towards increasing aridity preceding the onset of the Last Glacial Maximum and a period of increased humidity in the early to mid-Holocene. Enamel δ13C reflects divergent species feeding ecology and may imply a long-term shift toward increasing diversity in vegetation structure. This study contributes new data to the carbonate-isotope record for Australian fauna and demonstrates the significant potential of stable isotope based ecological investigations for tracking paleoenvironment change to inter-strata resolution.

Archaeological deposits from Boodie Cave on Barrow Island, northwest Australia, reveal some of the oldest evidence for Aboriginal occupation of Australia, as well as illustrating the early use of marine resources by modern peoples outside of Africa. Barrow Island is a large (202 km 2 ) limestone continental island located on the North-West Shelf of Australia, optimally located to sample past use of both the Pleistocene coastline and extensive arid coastal plains. An interdisciplinary team forming the Barrow Island Archaeology Project (BIAP) has addressed questions focusing on the antiquity of occupation of coastal deserts by hunter-gatherers; the use and distribution of marine resources from the coast to the interior; and the productivity of the marine zone with changing sea levels. Boodie Cave is the largest of 20 stratified deposits identified on Barrow Island with 20 m 3 of cultural deposits excavated between 2013 and 2015. In this first major synthesis we focus on the dating and sedimentology of Boodie Cave to establish the framework for ongoing analysis of cultural materials. We present new data on these cultural assemblages – including charcoal, faunal remains and lithics – integrated with micromorphology, sedimentary history and dating by four independent laboratories. First occupation occurs between 51.1 and 46.2 ka, overlapping with the earliest dates for occupation of Australia. Marine resources are incorporated into dietary assemblages by 42.5 ka and continue to be transported to the cave through all periods of occupation, despite fluctuating sea levels and dramatic extensions of the coastal plain. The changing quantities of marine fauna through time reflect the varying distance of the cave from the contemporaneous shoreline. The dietary breadth of both arid zone terrestrial fauna and marine species increases after the Last Glacial Maximum and significantly so by the mid-Holocene. The cave is abandoned by 6.8 ka when the island becomes increasingly distant from the mainland coast. [ABSTRACT FROM AUTHOR]

The significance of the role of birds in hominin evolution in Island Southeast Asia is not clear. Few avian vertebrate deposits have been recovered from archaeological or fossil sites in the region, and their association with either hominin or natural deposition in caves and rock shelters complicates their usefulness in hominin behavioural and palaeoecological reconstructions. In this paper, we assess the taphonomic history of the Pleistocene avian vertebrate remains recovered from Laili Cave, Timor-Leste, dated to between ca. 44.6 to 11.2 ka and in association with abundant lithic material. We use avian taxonomic composition, skeletal element abundance, and bone surface modification data to determine the agent of avian skeletal deposition. Our analyses indicate that the small grassland and woodland birds (quail, buttonquail, song birds), which dominate the assemblage, were deposited by avian predators (probably barn owls) throughout the sequence. Humans possibly hunted the small quantity of larger birds (imperial pigeon, duck). The bird remains suggest that grasslands, woodland savannahs, wetlands, and forest environments were present locally during the Pleistocene. [ABSTRACT FROM AUTHOR]

We present Bayesian modelling on a long sequence of radiocarbon ages from the archaeological site of Nawarla Gabarnmang, central Arnhem Land plateau, northern Australia. A horizon of wind-borne sediments containing flaked stone artefacts and charcoal commencing >45,610 cal BP (the young end of the modelled boundary age range, which extends beyond the limit of the calibration curve), with a median modelled age of 48,500 cal BP, signals the onset of aeolian mobilisation of fine sands and silts across the landscape, and re-deposition within the site at a time synchronous with the first evidence of people. This earliest cultural horizon (Stratigraphic Unit 4) contains 509 stone artefacts, and is marked by a contemporaneous sedimentary break, from underlying culturally sterile sediments consisting of disintegrating roof-fall and in situ sandstone and quartzite to overlying culturally-rich wind-blown sand. The new radiocarbon ages and wind-blown sediments together provide evidence for the commencement of noticeable landscape burning on the Arnhem Land plateau c. 48,500 cal BP, suggesting an intensification of landscape management practices at the summit of the Arnhem Land plateau some 10,000–15,000 years after the lowest dense band of artefacts (Phase 2) at Madjedbebe on the floodplains 90 km to the north. These results have ramifications for the structure and timing of the spread of people across Australia, and the extinction of megafauna in Sahul. • Radiocarbon ages spanning the past c. 48,500 years of human occupation are presented for Nawarla Gabarnmang, north Australia. • Earliest flaked stone artefacts and in situ charcoal appear in tandem. • The first stone artefacts and charcoal appear within the site with the onset of aeolian sediments. • The earliest artefacts, in situ charcoal and aeolian sediments overlie soft sediments originating from roof-fall. • The onset of aeolian sediments with artefacts and charcoal in the site suggest anthropic landscape modifications 45,610–52,160 years ago. • These results suggest permanent occupation of the rugged Arnhem Land plateau > 10,000 years after the northern floodplains.

Increasing diet breadth, a distinguishing characteristic of human foraging strategies at the end of the Pleistocene and in the early Holocene, is known to be a key development contributing to domestication and the spread of agriculture and pastoralism. Many scholars have focused on broad-spectrum foraging as a result of resource depression due to demographic stress or environmental degradation. However, these factors are absent in an increasing number of cases. New research in the Gobi Desert shows that a dramatic change in organizational strategies, including the intensified use of low-ranked foods from dune-field and wetland habitats, is closely correlated with the establishment of dispersed patches boasting high species diversity and a concentrated abundance of small prey. According to a global suite of paleoenvironmental and archaeological data, it appears that the fragmentation of more homogeneous grassland habitats coincided with the rise of broad-spectrum foraging and that these fragmented ecosystems were ideally suited to the unique set of foraging strategies employed by modern Homo sapiens. This study shows how broad-spectrum foraging, increased human population density, and the shift toward food production should be considered by-products of major environmental changes that created an ecological setting ideal for enhanced human reproduction.

• Marra Australian Aboriginal philosophies guide archaeological research. • Stone artefacts are embedded within Marra relational philosophies and politics. • Stone 'raw materials' are potent ancestral substances. • Access to powerful Marra ancestral quarries changed through time. • Lithic analyses of Marra stone artefacts reveal changing social worlds. In archaeology, investigations into the social and cultural contexts of stone artefacts have largely focused on their typological styles, manufacturing technologies, functions, geographic distributions and the significance of the quarries they come from. Yet what is oftentimes overlooked is the deeper contemporary understandings by Indigenous groups of the stone artefacts recovered from excavations. In this paper, we analyse an assemblage of 9,642 excavated stone artefacts from the rockshelter site of Walanjiwurru 1 in Marra Country in northern Australia, in light of the cosmological significance of regional stone sources to local Aboriginal groups. Each recovered stone artefact, and the quarries of their raw materials, is laden with meanings that help reveal how Marra Aboriginal people socially and cosmologically engaged with their landscape. By combining archaeological and Marra cultural perspectives, we argue that subtle variations in the range of stones and their relational characteristics signal changing political engagements with ancestral places over the past 2300 years.

Published ages of >50 ka for occupation at Madjedbebe (Malakunanja II) in Australia's 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. [ABSTRACT FROM AUTHOR]

The distribution of food in space and time influences hunter-gatherer settlement and subsistence patterning in generalizable ways. In North Slope, Alaska, where caribou (Rangifer tarandus) are abundant annually in predictable locations, storage equalizes availability across relative scarcity. This study examined an assemblage of caribou long-bone specimens from an activity area at the Croxton archaeological site for evidence of mass processing for bone-marrow storage outside of the meal course as an indicator of production efficiency in an economy of scale. The archaeological faunal samples were compared on three criteria with ethnoarchaeological meal-midden and mass-processing model assemblages. The analysis indicated that the archaeological specimens are short and variable and are not biased toward marrow-rich skeletal elements, indicating that they probably resulted from meal middens and not from marrow mass-processing debris. The results of this study suggest that meal-based access to a full spectrum of nutrient sources was emphasized over efficiency in marrow extraction and storage in the archaeological faunal samples. This study demonstrates that analyzes of faunal remains based on models of subsistence organization can be useful in the development of perspectives about past food systems. [ABSTRACT FROM AUTHOR]
