Recent archaeological investigations at Widgingarri Shelter 1, northwest Australia
Site Formation History of Widgingarri Shelter 1, Northwestern Australia and Investigation of Postdepositional Disturbance With Single‐Grain OSL Dating and Soil Micromorphology
Widgingarri Shelter 1 (WS1) is a rock shelter site within a small escarpment and preserves evidence of late Pleistocene and Holocene human activity. The site was first excavated in 1985 and again in 2022. Here, we present the stratigraphy and chronology following the latter excavation. Site context and stratigraphy were investigated through field observations of the landscape, site and soil micromorphology. A chronological framework was establish…
Use-polished stone flakes from Liang Bua, Indonesia
Edge-glossed flakes, usually recognised as stone tools with macroscopically visible polish from use, have been documented in parts of Southeast Asia from contexts spanning the past 12,000 years and possibly more than 30,000 years. It has been proposed that the edges of these flakes were polished by cutting, splitting or otherwise processing siliceous and fibrous plants for matting, basketry and bindings, and possibly by the reaping of cereals suc…
The acid test
Caves in tropical regions form a key resource for those reconstructing human evolution and dispersals. However, the complex sedimentary records they contain remain under-interpreted because of the poorly constrained effects of humid tropical climates upon archaeological site formation processes. Guano-driven phosphatic diagenesis impacts archaeological preservation in caves, but atypical features observed in guano layers in prominent Southeast As…

The Pleistocene geoarchaeology and geochronology of Con Moong Cave, North Vietnam
This paper presents the results of geoarchaeological and geochronological investigations at Con Moong Cave, North Vietnam. Beneath the published, terminal Pleistocene sequence, recent excavations have uncovered a ~5 m stratigraphic sequence containing flaked stone artifacts and sedimentary features that indicate extensive post‐depositional change. As the effects of tropical conditions on Pleistocene cave sediments are poorly resolved, a range of …

The monograph discusses key results obtained in a multidisciplinary study of assemblages recovered from Chagyrskaya Cave, a unique Middle Paleolithic site of North Asia. This publication presents archaeological, anthropological, palynological, palaeontological, geological and paleogeographical data, as well as absolute age determinations. Investigations undertaken during 2007–2015 enable reconstruction of the Neanderthal subsistence strategies in…
Reply to comments on Clarkson et al. (2017) ‘Human occupation of northern Australia by 65,000 years ago’
We thank the authors for their comments in the previous issue of Australian Archaeology. The 2012-2015 research at Madjedbebe offers a new and comprehensive look at the early occupation of Sahul and adds substantially to our knowledge of the timing of that event and the behaviour of the first people to enter the region. Establishing occupation of northern Australia by 65 ± 6 thousand years ago (ka, with the uncertainty expressed at 95.4% probabil…
Incorporating terpenes, monoterpenoids and alkanes into multiresidue organic biomarker analysis of archaeological stone artefacts from Liang Bua (Flores, Indonesia)
A sensitive and selective gas chromatography-tandem mass spectrometry (GC–MS/MS) method for the detection and quantification of terpenes, monoterpenoids and alkanes was developed and validated, to complement an existing analytical workflow set up for organic biomarker analysis of stone artefacts. This method was applied to seven stone artefacts—six of which contained potential use-residues based on a previous study using non-volatile low molecula…
Raman spectroscopy of lipid micro-residues on Middle Palaeolithic stone tools from Denisova Cave, Siberia
The spatio-temporal distribution of archaeological and faunal finds at Liang Bua (Flores, Indonesia) in light of the revised chronology for Homo floresiensis
Liang Bua, the type site of Homo floresiensis, is a limestone cave on the Indonesian island of Flores with sedimentary deposits currently known to range in age from about 190 thousand years (ka) ago to the present. Recent revision of the stratigraphy and chronology of this depositional sequence suggests that skeletal remains of H. floresiensis are between ∼100 and 60 ka old, while cultural evidence of this taxon occurs until ∼50 ka ago. Here we e…

The chronostratigraphy of the Haua Fteah cave (Cyrenaica, northeast Libya) — Optical dating of early human occupation during Marine Isotope Stages 4, 5 and 6
Friday essay
Over the past half century, Australia has experienced a ‘time revolution’ with Indigenous history pushed back into the dizzying expanse of deep time. The latest discovery reminds us that science, like history, is an ongoing inquiry
Single-grain OSL chronologies for the Still Bay and Howieson's Poort industries and the transition between them
Luminescence ages for three ‘Middle Palaeolithic’ sites in the Nihewan Basin, northern China, and their archaeological and palaeoenvironmental implications
The Nihewan Basin is a key region for studying the Palaeolithic archaeology of East Asia. However, because of the lack of suitable dating methods and representative lithic technologies in this region, the ‘Middle Palaeolithic’ sites in this basin have been designated based mainly on stratigraphic correlation, which may be unreliable. In this study, three Palaeolithic sites, Motianling, Queergou and Banjingzi, which have been assigned previously t…

Archaeological evidence for indigenous human occupation of Southern Arabia at the Pleistocene/ Holocene transition
The Neolithic peopling of Arabia is a subject of increasing debate, as different scenarios are proposed to describe the relatively sudden appearance of seemingly homogeneous archaeological sites throughout the south of the Peninsula during the Early Holocene. Such sites are identified by the co-occurrence of a laminar core reduction strategy with its supposed fossile directeur, the “ Fasad point.” This techno-typological package has been used by …
Optical Dating of Single and Multiple Grains of Quartz From Jinmium Rock Shelter, Northern Australia
Jinmium rock shelter is famous for the claims made by Fullagar et al. (1996) for the early human colonization and ancient rock art of northern Australia. These claims were based on thermo‐luminescence ages obtained for the artefact‐bearing quartz sediments that form the floor deposit at the site. In this paper, we outline the background to the optical dating programme at Jinmium, and describe the experimental design and statistical methods used t…

Optical Dating of Single and Multiple Grains of Quartz From Jinmium Rock Shelter, Northern Australia
Quartz sediments from the floor deposit at Jinmium rock shelter have been investigated using the multiple‐grain and single‐grain optical dating methods described by Galbraith et al. (1999, this volume). Here we present the results of this dating programme and argue that the artefact‐bearing sediments were deposited within the last 10000 years. This time interval is consistent with the radiocarbon chronology but is much younger than previous claim…

The Emergence of a Grain Market in Bamako, 1883-1908
RÉSUMÉLe marché des grains de Bamako apparaît comme une réponse à la demande de l'Etat colonial et des employeurs de la main-d'oeuvre salariée. Les profits du commerce et de la spéculation ont souvent été substantiels pour les marchands européens et africains qui y ont participé. Deux explications du développement de ce marché peuvent être offertes. La première souligne la taille de la population engagée dans la production des grains pour la vent…

An evaluation of radiocarbon chronologies at Miriwun rock shelter and the Monsmont site, Ord valley, east Kimberley, Western Australia
Miriwun rock shelter, since the early 1970s permanently inundated in Lake Argyle in the Ord valley, east Kimberley, Western Australia, was the first Aboriginal occupation site of Pleistocene age to be recorded in Western Australia's sub-tropical northwest (Dortch 1972, 1977a). Miriwun and the Stonewall Creek open-air site 35 km to the north (Dortch 1977b) provide the only unequivocal 'two-phase' stone industrial sequences yet recorded in the Ord …
New optical and radiocarbon dates from Ngarrabullgan Cave, a Pleistocene archaeological site in Australia
The human settlement of Australia falls into that period where dating is hard because it is near or beyond the reliable limit of radiocarbon study; instead a range of luminescence methods are being turned to (such as thermoluminescence at Jinmium: December 1996 ANTIQUITY). Ngarrabullgan Cave, a rock-shelter in Queensland, now offers a good suite of radiocarbon determinations which match well a pair of optically stimulated luminescence (OSL) dates…
