There are numerous ethnographic reports describing the processing of animal parts, but identification of collagen, the principle component of animal protein, can be difficult because of the similarity in appearance to other non-collagenous residues (e.g. Lombard and Wadley, 2007). Additionally, damage to collagen structure caused by processing and taphonomic factors can alter collagen's microscopic morphological features and further prevent microscopic identification. This paper describes the trialling, blind testing and application of a modified Picro-Sirius Red (PSR) staining protocol not reliant on intact morphology which can be used to identify archaeological collagenous residues. The protocol allows for differentiation of Types I, II and III collagen and can detect the minuscule amounts in archaeological samples. The application of this staining protocol to ten grindstones from arid and semiarid regions in south and central Australia supports the view that lack of collagen heretofore reported in residue studies is more likely the result of under-detection than its absence (see Monnier et al., 2012). The staining protocol represents an inexpensive, efficient and reliable process which can be added to contemporary use-wear and residue analyses. This addition allows more inclusive assessments of past function and promotes wider understandings of the behaviour of past peoples.

Yet some artefacts hold such cultural significance that sampling is inappropriate, restricting the methods that can be brought to bear in their analysis. Such restrictions often apply to rock art, especially where research is directed by the indigenous peoples who have stewardship over not only the site fabric, but its inseparable cultural context. Here we report a multi-technique program of in-field and laboratory-based analyses to describe the materiality of a painted rock art site in Nyiyaparli country, in the Central Pilbara region of Western Australia. The relationship between the rock art, nearby potential pigment sources and evidence for ochre processing at the site was investigated using in situ portable X-Ray Fluorescence and optical microscopy, with interpretations aided by field and laboratory-based residue analysis of grinding related stone artefacts and X-Ray Powder Diffraction of potential ochre sources. Our findings provide an example of the nuanced interpretations that scientific analyses can add to rock art investigations. Our work suggests that local materials were used in the production of painted art and that ochre processing was ubiquitous at the site and other nearby rockshelters. Combined with the placement of rock art in a hidden context within the site, we suggest the panels at BBH15-01 were part of in-group events and that art and ochre processing in the Baby Hope study area were part of everyday activities.

Humans colonized the continent by 50 ka, but an apparent lack of cultural innovations compared to people in Europe and Africa 3,4 has been deemed a barrier to early settlement in the extensive arid zone. Here we present evidence from Warratyi rock shelter in the southern interior that shows that humans occupied arid Australia by around 49 ka, 10 thousand years (kyr) earlier than previously reported. The site preserves the only reliably dated, stratified evidence of extinct Australian megafauna, including the giant marsupial Diprotodon optatum, alongside artefacts more than 46 kyr old. We also report on the earliest-known use of ochre in Australia and Southeast Asia (at or before 49-46 ka), gypsum pigment (40-33 ka), bone tools (40-38 ka), hafted tools (38-35 ka), and backed artefacts (30-24 ka), each up to 10 kyr older than any other known occurrence. Thus, our evidence shows that people not only settled in the arid interior within a few millennia of entering the continent, but also developed key technologies much earlier than previously recorded for Australia and Southeast Asia.

In Australia, grinding and pounding stones are ubiquitous across the semi-arid and arid zones and the associated tasks have been mostly informed by ethnographic case studies. More recently, plant microfossil studies have provided important insights to the breadth of plants being exploited in a range of contexts and over long time periods. The preservation of starch and/or phytoliths on the used surfaces of these artefacts is well documented, though the factors determining the survival or destruction of use-related starch residues are still largely unknown. Some of these artefacts have also been used for grinding up small animals and these tasks can be identified by specific staining methods for organic remains such as collagen. In this study, 25 grinding and pounding stones identified during an archaeological project in arid South Australia, were examined for starch and collagen residues. The artefacts were from 3 locations in central South Australia, all located in exposed settings. Of these localities, Site 11 in the Western Valley near Woomera is an important Aboriginal landscape specifically associated with male ceremonial practice in the recent past. The remaining two sites, one in the adjacent Nurrungar Valley and the other near Andamooka 100 km distant, have unrestricted access and potentially a different suite of residues. The Kokatha Mula Nations, the Traditional Owners of Woomera, requested that this study be undertaken to explore the range of plants that may have been processed here. It provided an opportunity to investigate the preservation potential of starch and collagen on grinding stones; explore the range of taphonomic factors involved in the persistence of residues in extreme environmental conditions; and test the methodological developments in identifying specific plant origin of starch residues. Of the 25 grinding/pounding stones tested, 7 yielded starch grains. Geometric morphometric analysis identified 3 economic grass species, Crinum flaccidum (Andamooka Lily) and Typha domingensis (Bulrush/Cumbungi). Folded collagen was identified on one artefact. Oral histories recount the movement between Andamooka and Nurrungar/Western Valley for men's ceremonies, and documented in the movement of stone resources, e.g. oolytic chert. The survival of residues in this environment and the identification of economic plant taxa complement the current knowledge of ceremonial activities and the movement of people and resources across significant dis-tances in arid South Australia.

In Europe, collective ritual performance is expected to be highly structured and to leave behind a loud archaeological signature. In Australia and Papua New Guinea, ritual is highly structured; however, material signatures for performance are not always apparent, with ritual frequently bound up in the surrounding natural and cultural landscape. One way of assessing long-term ritual in this context is by using archaeology to historicize ethno-historical and ethnographic accounts. Examples of this in the Torres Strait region, islands between Papua New Guinea and mainland Australia, suggest that ritual activities were materially inscribed at kod sites (ceremonial men's meeting places) through distribution of clan fireplaces, mounds of stone/bone and shell. This paper examines the structure of Torres Strait ritual for a site ethnographically reputed to be the ancestral kod of the Mabuyag Islanders. Intra-site partitioning of ritual performance is interpreted using ethnography, rock art and the divergent distribution of surface and sub-surface materials (including microscopic analysis of dugong bone and lithic material) across the site. Finally, it discusses the materiality of ritual at a boundary zone between mainland Australia and Papua New Guinea and the extent to which archaeology provides evidence for Islander negotiation through ceremony of external incursions.

Detailed chronometric dating, combined with high-resolution 3D mapping, geomorphological studies and archaeological excavations, now allow a dense sequence of Late Holocene ash layers and their contents to be correlated with GunaiKurnai ethnography and current knowledge. These results suggest a critical re-interpretation of what the Old People were, and were not, doing in Cloggs Cave during the Late Holocene. Instead of a lack of Late Holocene cave occupation, as previously thought through the conceptual lens of ‘habitat and economy’, Cloggs Cave is now understood to have been actively used for special, magical purposes. Configured by local GunaiKurnai cosmology, cave landscapes (including Cloggs Cave’s) were populated not only by food species animals, but also by ‘supernatural’ Beings and forces whose presence helped inform occupational patterns. The profound differences between the old and new archaeological interpretations of Cloggs Cave, separated by five decades of developing archaeological thought and technical advances, draw attention to archaeological meaning-making and highlight the significance of data capture and the pre-conceptions that shape the production of archaeological stories and identities of place.

Working in conjunction with the Traditional Owners and Parks Victoria, slumped hearth and midden deposits were excavated carefully, and samples sent to specialists for analysis. The remainder of the intact feature was photographed in 3D and then preserved by the construction of a rock-retaining wall by Parks Victoria. The results of the scientific analyses have yielded insights into the activities that took place in the vicinity of the hearth around the time of first contact between Aboriginal and European people, and illustrate the potential for similar studies to be undertaken on comparable deposits at other Aboriginal places.

During the archaeological salvage works, a series of twelve 25 m2 salvage areas were excavated, with over 17,000 Aboriginal stone artefacts recovered. This paper focuses on an extraordinarily high-density stone artefact assemblage (over 13,000 artefacts) identified within one of these investigation areas adjacent to Kororoit Creek, where stone artefact attribute and residue/use-wear analyses of the assemblage permit a glimpse of the range of past land-use activities that occurred within the Rockbank landscape. However, 3D distributional analysis of the archaeological material indicates that the assemblage does not represent a stratigraphically intact deposit, as much of the assemblage was transported by post-depositional processes. Through examination by a series of specific research questions, this work enhances our understanding of the nature of Aboriginal occupation on the Volcanic Plains of western Victoria.

This paper examines the application of three biochemical staining protocols to investigate activities associated with a rock shelter site Wirrilee 2 located in the Carnarvon Ranges (Katjarra) in the Western Desert of Western Australia. Previous research at the nearby site of Serpents Glen indicates that Katjarra (or Carnarvon Ranges), homeland to the hunter-gatherer Martu people, has been occupied for at least 26,000 years. It is inferred that over this period of time an array of activities relating to subsistence, medicine, hunting and ceremony would have been undertaken. The site of Wirrilee 2 contains a number of potential grinding circles or work areas. In-situ grinding furniture in the form of top stones is associated with two of these eight activity areas. In addition, a large section of roof fall exhibiting ground or worked surface sections was identified. These indicators of past processing, along with the site’s proximity to nearby rock art sites and extensive grassy plains, made it an ideal site for undertaking investigations relating to past processing activities. This talk will discuss the results of this study and the biochemical staining approaches employed. If time permits, the results of a related study investigating the use of nearby open context grindstones will also be presented.

A major strength of this approach is that functional assessments are determined independent of form and associated typological assumptions. Its reliability, however, is dependent on the accuracy of the analysts to reliably identify microscopic residues. Lombard and Wadley (2007:155) have highlighted interpretative issues associated with the morphological similarities of some faunal and plant residues. Additionally residues may become unidentifiable when their microscopic diagnostic features have been damaged by activities such as cooking and drying or by the mechanical forces associated with pounding and grinding (Babot 2003). As such a need for an additional identification method which is not largely dependent on the visualization of microscopic diagnostic features is highlighted. In particular, the unequivocal identification of animal residues regardless of any associated processing activities is essential for achieving unambiguous functional understandings. This paper reports on the development, adaptation and application of a biochemical staining protocol designed to highlight animal specific residues within archaeological contexts. In particular its application for identifying ground residues associated with grindstones, grinding hollows and grinding patches is demonstrated.

A proposed subsistence shift leading to an increased reliance on seed during the late Holocene currently underpins a number of Australian arid zone settlement and social models. The late Holocene appearance of millstones, which, according to Smith’s (1985, 1986, 1988) functional grindstone typology represents a formal, specialised seed-grinding tool, is frequently cited as evidence of this shift. Yet this typological classification is challenged by others who recognise the millstone as a multi-purpose grinder whose particular form relates to the end stage of a variable reduction process rather than specialised function (Gorecki et al. 1997). Past use-wear and residue analysis studies of grindstones have frequently been impeded by methodological issues relating to grindstone morphology, sample size, identification of grinding fragments, and perceived interpretative weaknesses associated with use-wear and residue analyses generally (see Balme et al. 2001:4; Crowther and Haslam 2007:999; Hiscock and Clarkson 2000:100; Smith 2004:170). As such, in Australia, millstone function currently remains equivocal. To resolve these interpretative issues and the disparate views of millstone function, a sampling strategy based on extensive experimental work, portable digital microscopy and innovative biochemical staining, are integrated into recognised use-wear and residue analyses to empirically assess the function of ten arid zone Holocene millstones from Queensland, Australia. The resulting expanded hierarchy of evidence allows for more informed assessments of past behaviour and has the potential to directly contribute towards the resolution of a number of seminal Australian arid zone debates.

In addition to damaged residues, intact residues such as plant fibres, phyoliths, starches, minerals, barbules and the like remain unaffected and are clearly observed. The addition of biochemical staining permits definitive assessments of similar plant and animal residues. As such, these staining approaches allow for more inclusive assessments of past function and contribute to more informed understandings of past behaviour. While these approaches can be used to investigate a variety of archaeological material, this poster demonstrates the utility of uncomplicated biochemical staining methods to investigate the function of grindstones from Australian contexts. The wide array of residues and their preservation is fascinating and supports suggestions of multiple and contrasting uses. Biochemical staining represents an inexpensive, simple, value-adding, nondestructive additional residue approach that is being applied successfully in Australia and overseas. If you thought Masterchef was cool then you need to view the colourful world of staining and see the residues associated with the kitchens and preparation areas of the past.

Results suggest discrete areas of artefact use including modification of bone, plant-processing and ‘symbolic’ activities that required treatment of artefacts involving red and yellow ochre. This case study is put within a broader context of late Holocene ceremonial activities observed across western Torres Strait.

Previous research has emphasised the exploitation of largely terrestrial resources by hunter-gatherers on the island. The recent recovery of two modified tiger shark teeth from the Maros-Pangkep karsts of South Sulawesi, however, offers new insights. The authors combine use-wear and residue analyses with ethnographic and experimental data to indicate the use of these artefacts as hafted blades within conflict and ritual contexts, revealing hitherto undocumented technological and social practices among Toalean hunter-gatherers. The results suggest these artefacts constitute some of the earliest archaeological evidence for the use of shark teeth in composite weapons.

Yet some artefacts hold such cultural significance that sampling is inappropriate, restricting the methods that can be brought to bear in their analysis. Such restrictions often apply to rock art, especially where research is directed by the indigenous peoples who have stewardship over not only the site fabric, but its inseparable cultural context. Here we report a multi-technique program of in-field and laboratory-based analyses to describe the materiality of a painted rock art site in Nyiyaparli country, in the Central Pilbara region of Western Australia. The relationship between the rock art, nearby potential pigment sources and evidence for ochre processing at the site was investigated using in situ portable X-Ray Fluorescence and optical microscopy, with interpretations aided by field and laboratory-based residue analysis of grinding related stone artefacts and X-Ray Powder Diffraction of potential ochre sources. Our findings provide an example of the nuanced interpretations that scientific analyses can add to rock art investigations. Our work suggests that local materials were used in the production of painted art and that ochre processing was ubiquitous at the site and other nearby rockshelters. Combined with the placement of rock art in a hidden context within the site, we suggest the panels at BBH15-01 were part of in-group events and that art and ochre processing in the Baby Hope study area were part of everyday activities.

In Europe, collective ritual performance is expected to be highly structured and to leave behind a loud archaeological signature. In Australia and Papua New Guinea, ritual is highly structured; however, material signatures for performance are not always apparent, with ritual frequently bound up in the surrounding natural and cultural landscape. One way of assessing long-term ritual in this context is by using archaeology to historicize ethno-historical and ethnographic accounts. Examples of this in the Torres Strait region, islands between Papua New Guinea and mainland Australia, suggest that ritual activities were materially inscribed at kod sites (ceremonial men's meeting places) through distribution of clan fireplaces, mounds of stone/bone and shell. This paper examines the structure of Torres Strait ritual for a site ethnographically reputed to be the ancestral kod of the Mabuyag Islanders. Intra-si...

In this paper, we map the distribution of use-polish and residues on a classic Central Australian millstone. We begin by setting out an explanatory 'cradle–to–grave' model of the dynamics of millstones to assist our interpretations. We then apply various methods of functional analysis to map the distribution of microwear and residues across the millstone. Several dynamics are evident: (1) the kinetics of grinding create spatial variability in use–polish and residues; (2) systemic factors lead to a palimpsest of different residues, not all of which relate to the major function of the implement; and (3) various systemic factors degrade some of the traces on millstones well before they are buried. Our results for this Central Australian millstone show that there is substantial variability within and between grinding grooves, reflecting the continuing attrition of these surfaces. Starch, which was presumably a primary residue, is poorly preserved, even on the most recent ground surfaces. There is a diversity of other residues present, reflecting secondary use of this millstone as an impromptu work surface. We conclude that the long systemic use–lives of these durable implements can complicate their identification as seed–grinders, and raise issues for future functional research.

In Australia, early settler writings from the 1830s to mid-1800s reported congregations of Aboriginal groups from multiple clans and language groups taking advantage of the annual migration of Bogong moths (Agrotis infusa) in and near the Australian Alps, the continent’s highest mountain range. The moths were targeted as a food item for their large numbers and high fat contents. Within 30 years of initial colonial contact, however, the Bogong moth festivals had ceased until their recent revival. No reliable archaeological evidence of Bogong moth exploitation or processing has ever been discovered, signalling a major gap in the archaeological history of Aboriginal groups. Here we report on microscopic remains of ground and cooked Bogong moths on a recently excavated grindstone from Cloggs Cave, in the southern foo...

Humans colonized the continent by 50 ka, but an apparent lack of cultural innovations compared to people in Europe and Africa has been deemed a barrier to early settlement in the extensive arid zone. Here we present evidence from Warratyi rock shelter in the southern interior that shows that humans occupied arid Australia by around 49 ka, 10 thousand years (kyr) earlier than previously reported. The site preserves the only reliably dated, stratified evidence of extinct Australian megafauna, including the giant marsupial Diprotodon optatum, alongside artefacts more than 46 kyr old. We also report on the earliest-known use of ochre in Australia and Southeast Asia (at or before 49-46 ka), gypsum pigment (40-33 ka), bone tools (...

Detailed chronometric dating, combined with high-resolution 3D mapping, geomorphological studies and archaeological excavations, now allow a dense sequence of Late Holocene ash layers and their contents to be correlated with GunaiKurnai ethnography and current knowledge. These results suggest a critical re-interpretation of what the Old People were, and were not, doing in Cloggs Cave during the Late Holocene. Instead of a lack of Late Holocene cave occupation, as previously thought through the conceptual lens of ‘habitat and economy’, Cloggs Cave is now understood to have been actively used for special, magical purposes. Configured by local GunaiKurnai cosmology, cave landscapes (including Cloggs Cave's) were populated not only by food species animals, but also by ‘supernatural’ Beings and forces whose p...

This paper focuses on an extraordinarily high-density stone artefact assemblage (over 13,000 artefacts) identified within one of these investigation areas adjacent to Kororoit Creek, where stone artefact attribute and residue/use-wear analyses of the assemblage permit a glimpse of the range of past land-use activities that occurred within the Rockbank landscape. However, 3D distributional analysis of the archaeological material indicates that the assemblage does not represent a stratigraphically intact deposit, as much of the assemblage was transported by post-depositional processes. Through examination by a series of specific research questions, this work enhances our understanding of the nature of Aboriginal occupation on the Volcanic Plains of western Victoria.

Previous research at the nearby site of Serpents Glen indicates that Katjarra (or Carnarvon Ranges), homeland to the hunter-gatherer Martu people, has been occupied for at least 26,000 years. It is inferred that over this period of time an array of activities relating to subsistence, medicine, hunting and ceremony would have been undertaken. The site of Wirrilee 2 contains a number of potential grinding circles or work areas. In-situ grinding furniture in the form of top stones is associated with two of these eight activity areas. In addition, a large section of roof fall exhibiting ground or worked surface sections was identified. These indicators of past processing, along with the site’s proximity to nearby rock art sites and extensive grassy plains, made it an ideal site for undertaking investigations relating to past processing activities. This talk will discuss the results of this study and the biochemical staining approaches employed. If time permits, the results of a related study investigating the use of nearby open context grindstones will also be presented.
