Mammalian extinction worldwide during the Late Pleistocene has been a major focus for Quaternary biochronology and paleoecology. These extinctions have been variably attributed to the impacts of climate change and human interference. However, until relatively recently, research has been largely restricted to the Americas, Europe, and Australasia. We present the oldest Middle-Late Pleistocene stratified and numerically dated faunal succession for the Indian subcontinent from the Billasurgam cave complex. Our data demonstrate continuity of 20 of 21 identified mammalian taxa from at least 100,000 y ago to the present, and in some cases up to 200,000 y ago. Comparison ...


A Single-Aliquot Luminescence Dating Procedure For K-Feldspar Based On The Dose-Dependent Met-Pirir Signal Sensitivity, Bo Li, Richard G. Roberts, Zenobia Jacobs, Sheng-Hua Li Jan 2014

A Single-Aliquot Luminescence Dating Procedure For K-Feldspar Based On The Dose-Dependent Met-Pirir Signal Sensitivity, Bo Li, Richard G. Roberts, Zenobia Jacobs, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

It has been shown previously that the ‘sensitivity’ of the post-infrared infrared stimulated luminescence (post-IR IRSL or pIRIR) signal—that is, the intensity of the test dose signal (Tx)—can retain a ‘memory’ of the pre-dose received in nature, but can be reset by sunlight bleaching. Based on this observation, we describe here a single-aliquot regenerative-dose (SAR) multiple elevated temperature (MET) pIRIR dating procedure for K-feldspar that differs in one important respect from the conventional SAR MET-pIRIR procedure. Instead of using a high temperature IR bleaching step between each SAR cycle—as in the conventional procedure—our modified procedure uses ...


Assessing The Time Of Final Deposition Of Youngest Toba Tuff Deposits In The Middle Son Valley, Northern India, Christina M. Neudorf, Richard G. Roberts, Zenobia Jacobs Jan 2014

Assessing The Time Of Final Deposition Of Youngest Toba Tuff Deposits In The Middle Son Valley, Northern India, Christina M. Neudorf, Richard G. Roberts, Zenobia Jacobs

Faculty of Science, Medicine and Health - Papers: part A

We present optical ages for quartz and K-feldspar grains extracted from sedimentary deposits above and below Youngest Toba Tuff (YTT) at two localities in the Middle Son Valley (MSV), Madhya Pradesh, India. These ash deposits have been the focus of past palaeoenvironmental investigations that aim to understand the effects of the ~ 74 ka Toba super-eruption on ecosystems and human populations in northern India. Age estimates from both quartz and feldspar grains post-date the Toba eruption and single-grain age distributions suggest that YTT ash-bearing sediments in the MSV are mainly composed of a mixture of recently sun-exposed, flood-transported grains and older ...

The Evolution Of A Terrace Sequence Along The Manas River In The Northern Foreland Basin Of Tian Shan, China, As Inferred From Optical Dating, Zhijun Gong, Sheng-Hua Li, Bo Li Jan 2014

The Evolution Of A Terrace Sequence Along The Manas River In The Northern Foreland Basin Of Tian Shan, China, As Inferred From Optical Dating, Zhijun Gong, Sheng-Hua Li, Bo Li

Faculty of Science, Medicine and Health - Papers: part A

The Tian Shan range lies in the actively deforming part of the India-Asia collision zone. The uplift rate and deformation pattern of the Tian Shan are important for understanding the dynamics of crustal deformation in the region. The river terraces in northern Tian Shan provide key records of past changes in climate and/or regional tectonics. In this study, a terrace sequence along the Manas River in a tectonically active zone in the northern foreland basin of Tian Shan is investigated. Six river terraces were identified and dated using optically stimulated luminescence (OSL). The results show that the six terraces ...


Testing A Model Of Alluvial Deposition In The Middle Son Valley, Madhya Pradesh, India - Irsl Dating Of Terraced Alluvial Sediments And Implications For Archaeological Surveys And Palaeoclimatic Reconstructions, Christina M. Neudorf, Richard G. Roberts, Zenobia Jacobs Jan 2014

Testing A Model Of Alluvial Deposition In The Middle Son Valley, Madhya Pradesh, India - Irsl Dating Of Terraced Alluvial Sediments And Implications For Archaeological Surveys And Palaeoclimatic Reconstructions, Christina M. Neudorf, Richard G. Roberts, Zenobia Jacobs

Faculty of Science, Medicine and Health - Papers: part A

Over the past three decades, the Middle Son Valley, Madhya Pradesh, India has been the focus of archaeological, geological, and palaeoenvironmental investigations that aim to reconstruct regional climate changes in the Late Pleistocene and to understand the effects of the ∼74 ka Toba super-eruption on ecosystems and human populations in northern India. The most recently published model of alluvial deposition for the Middle Son Valley subdivides its alluvium into five stratigraphic formations, each associated with a specific artefact assemblage. In this study, new cross-valley topographic profiles, field observations and infrared stimulated luminescence (IRSL) age estimates are used to refine this ...


Facial Approximation Of 'Angel': Case Specific Methodological Review, Susan Hayes Jan 2014

Facial Approximation Of 'Angel': Case Specific Methodological Review, Susan Hayes

Faculty of Science, Medicine and Health - Papers: part A

A forensic facial approximation is typically undertaken to generate further leads to identity of the deceased, and over the past ten years there has been a considerable increase in the number of verified relationships concerning the skull and likely facial appearance. This paper describes the evidence and methods used to approximate the face and facial features of a young woman whose remains were found in the Belanglo State Forest (New South Wales, Australia) in August 2010. A review of methodologically analogous forensic facial approximations (i.e. involving some degree of manual manipulation to achieve the results), and published in international ...

Pre-Pottery Neolithic assemblages are best known from the fertile areas of the Mediterranean Levant. The archaeological site of Jebel Qattar 101 (JQ-101), at Jubbah in the southern part of the Nefud Desert of northern Saudi Arabia, contains a large collection of stone tools, adjacent to an Early Holocene palaeolake. The stone tool assemblage contains lithic types, including El-Khiam and Helwan projectile points, which are similar to those recorded in Pre-Pottery Neolithic A and Pre-Pottery Neolithic B assemblages in the Fertile Crescent. Jebel Qattar lies ~500 kilometres outside the previously identified geographic range of Pre-Pottery Neolithic cultures. Technological analysis of the ...


Extending The Age Limit Of Luminescence Dating Using The Dose-Dependent Sensitivity Of Met-Pirir Signals From K-Feldspar, Bo Li, Zenobia Jacobs, Richard G. Roberts, Sheng-Hua Li Jan 2013

Extending The Age Limit Of Luminescence Dating Using The Dose-Dependent Sensitivity Of Met-Pirir Signals From K-Feldspar, Bo Li, Zenobia Jacobs, Richard G. Roberts, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

We investigated the sensitivity change of multiple-elevated-temperature (MET) stimulated post-infrared infrared-stimulated luminescence (MET-pIRIR) signals as a response to irradiation, sunlight bleaching and heating using samples from the Mu Us Desert, central China. A strong dose dependence of MET-pIRIR signal sensitivity was observed. The intensity of the test-dose signals (Tx) increase with the pre-dose received. Furthermore, the signal sensitivity can be reset by sunlight bleaching or heating. This suggests that both the electron traps and hole centres in K-feldspar can be bleached by sunlight, and can, therefore, be used for dating. Using the test-dose signal as a monitor for sensitivity change ...


Micro-Biomechanics Of The Kebara 2 Hyoid And Its Implications For Speech In Neanderthals, Ruggero D'Anastasio, Stephen Wroe, Claudio Tuniz, Lucia Mancini, Deneb T. Cesana, Diego Dreossi, Mayoorendra Ravichandiran, Marie Attard, William C. H Parr, Anne Agur, Luigi Capasso Jan 2013

Faculty of Science, Medicine and Health - Papers: part A

The description of a Neanderthal hyoid from Kebara Cave (Israel) in 1989 fuelled scientific debate on the evolution of speech and complex language. Gross anatomy of the Kebara 2 hyoid differs little from that of modern humans. However, whether Homo neanderthalensis could use speech or complex language remains controversial. Similarity in overall shape does not necessarily demonstrate that the Kebara 2 hyoid was used in the same way as that of Homo sapiens. The mechanical performance of whole bones is partly controlled by internal trabecular geometries, regulated by bone-remodelling in response to the forces applied. Here we show that the ...


The Effect Of Band-Tail States On The Thermal Stability Of The Infrared Stimulated Luminescence From K-Feldspar, Bo Li, Sheng-Hua Li Jan 2013

The Effect Of Band-Tail States On The Thermal Stability Of The Infrared Stimulated Luminescence From K-Feldspar, Bo Li, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

The thermal stability of the infrared stimulated luminescence (IRSL) signal from a sedimentary K-feldspar was investigated using isothermal decay study. It is observed that the isothermal decay of IRSL signal cannot be described using a first-order exponential decay function. Instead, the decay can be well described by considering the presence of band-tail states. Based on the isothermal decay results, a trap depth of ∼1.92 eV was obtained for the IRSL stimulated at 50 °C and the width of the band-tail states was found to be ∼0.37 eV below the conduction band edge. Deeper trap depths (up to ∼2 ...


On The Dose Dependency Of The Bleachable And Non-Bleachable Components Of Irsl From K-Feldspar: Improved Procedures For Luminescence Dating Of Quaternary Sediments, Bo Li, Richard G. Roberts, Zenobia Jacobs Jan 2013

On The Dose Dependency Of The Bleachable And Non-Bleachable Components Of Irsl From K-Feldspar: Improved Procedures For Luminescence Dating Of Quaternary Sediments, Bo Li, Richard G. Roberts, Zenobia Jacobs

Faculty of Science, Medicine and Health - Papers: part A

The infrared (IR) stimulated luminescence (IRSL) and post-IR IRSL (pIRIR) signals from K-feldspar can, for convenience, be divided into two components, bleachable and ‘non-bleachable’, where the latter corresponds to the ‘residual’ signal observed in sunlight-bleached samples. In this paper, we examine the non-bleachable component of IRSL of K-feldspar for several sedimentary samples from across Eurasia. We observed a large variability in the residual doses among these samples after prolonged exposure to sunlight. By employing multiple elevated temperature (MET) IR stimulations at 50–300 °C, we show that the residual dose increases systematically with stimulation temperature, attaining values as high as ...

Ever since the Neandertal (Homo neanderthalensis) type fossil was discovered in the Neander Valley of Germany in 1856, the species has been variously portrayed as knuckle-dragging cavemen and primitive members of the human family tree who became extinct as a result of being more stupid than members of our own species, Homo sapiens.


Early And Middle Holocene Hunter-Gatherer Occupations In Western Amazonia: The Hidden Shell Middens, Umberto Lombardo, Katherine Szabo, Jose M. Capriles, Jan-Hendrik May, Wulf Amelung, Rainer Hutterer, Eva Lehndorff, Anna Plotzki, Heinz Veit Jan 2013

We report on previously unknown early archaeological sites in the Bolivian lowlands, demonstrating for the first time early and middle Holocene human presence in western Amazonia. Multidisciplinary research in forest islands situated in seasonally-inundated savannahs has revealed stratified shell middens produced by human foragers as early as 10,000 years ago, making them the oldest archaeological sites in the region. The absence of stone resources and partial burial by recent alluvial sediments has meant that these kinds of deposits have, until now, remained unidentified. We conducted core sampling, archaeological excavations and an interdisciplinary study of the stratigraphy and recovered materials ...


Faces Of Homo Floresiensis (Lb1), Susan Hayes, Thomas Sutikna, Michael Morwood Jan 2013

Faces Of Homo Floresiensis (Lb1), Susan Hayes, Thomas Sutikna, Michael Morwood

Faculty of Science, Medicine and Health - Papers: part A

Since being excavated in 2003, the skull of LB1 (the holotype of Homo floresiensis) has been given many faces, though the details regarding how each was accomplished are typically few. Here we detail our application of known, and verified, relationships between the skull and soft tissues of anatomically modern humans to produce an evidence-based facial approximation of LB1. We then compare our results to nine pre-existing LB1 faces using geometric morphometrics. These analyses suggest our facial approximation differs in proportional facial width, upper lip height and nasal morphology. Some of these differences are likely due to a different interpretation of ...


Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart Jan 2012

Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart

Faculty of Science, Medicine and Health - Papers: part A

Interpreting the spread in equivalent-dose estimates is an important aspect of optically stimulated luminescence (OSL) dating. Ideally, prior to age estimation, an assessment should be made of the likely spread in equivalent dose due to dose-rate heterogeneity in the sediment. Such a procedure would greatly increase the validity of OSL ages, particularly for sediments susceptible to partial bleaching, and for sediments with coarse or poorly sorted grain-size distributions. In this paper we take a step towards a general model of dose-rate heterogeneity by simulating the 40K-derived beta dose to quartz. We present an experimental simulation of the 40K beta dose ...

Realizing The Potential Of Fluvial Archives Using Robust Osl Chronologies, Alastair C. Cunningham, Jakob Wallinga Jan 2012

Realizing The Potential Of Fluvial Archives Using Robust Osl Chronologies, Alastair C. Cunningham, Jakob Wallinga

Faculty of Science, Medicine and Health - Papers: part A

Optically Stimulated Luminescence (OSL) dating has enormous potential for interpreting fluvial sediments, because the mineral grains used for OSL dating are abundant in fluvial deposits. However, the limited light exposure of mineral grains during fluvial transport and deposition often leads to scatter and inaccuracy in OSL dating results. Here we present a statistical protocol which aims to overcome these difficulties. Rather than estimating a single burial age for a sample, we present ages as likelihood functions created by bootstrap re-sampling of the equivalent-dose data. The bootstrap likelihoods incorporate uncertainty from age-model parameters and plausible variation in the input data. This ...

The Tangarutu Invertebrate Fauna, Katherine Szabo, Atholl Anderson

Faculty of Science, Medicine and Health - Papers: part A

The island of Rapa presents an interesting lens through which to investigate human decisionmaking and resource-use patterns in a marginal environment. In addition to being small and isolated, Rapa is climatically marginal, being positioned on the southern fringe of the tropical Indo-West Pacific marine province. Most obviously, this geographical situation translates to restricted species diversity, with a great many common tropical taxa not able to survive the conditions. However, as pointed out by Preece (1995:345), it would be a mistake to see the marine fauna of marginal Polynesian islands as simply an impoverished subset of the tropical Indo-West Pacific ...


Pleistocene Survivors And Holocene Extinctions: The Giant Rats From Liang Bua (Flores, Indonesia), Elisa Locatelli, Rokhus Awe Due, Gerrit D. Van Den Bergh, Lars W. Van Den Hoek Ostende Jan 2012

Pleistocene Survivors And Holocene Extinctions: The Giant Rats From Liang Bua (Flores, Indonesia), Elisa Locatelli, Rokhus Awe Due, Gerrit D. Van Den Bergh, Lars W. Van Den Hoek Ostende

Faculty of Science, Medicine and Health - Papers: part A

Excavations at Liang Bua Cave yielded a large amount of micromammal remains, the major part of which are murids, and some can be referred to three different species of giant rats. Whilst Papagomys armandvillei is still living on Flores, the other two species, Papagomys theodorverhoeveni and Spelaeomys florensis went extinct late during the Holocene. In this paper, the fossil record of these species at Liang Bua Cave is discussed. These giant murids are a clear example of insular gigantism, and can be seen as end members of the Island Rule. Opposition against the general applicability of this 'rule' is mainly ...


Study Of The Relationship Between Infrared Stimulated Luminescence And Blue Light Stimulated Luminescence For Potassium-Feldspar From Sediments, Zhijun Gong, Bo Li, Sheng-Hua Li Jan 2012

Study Of The Relationship Between Infrared Stimulated Luminescence And Blue Light Stimulated Luminescence For Potassium-Feldspar From Sediments, Zhijun Gong, Bo Li, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

In luminescence measurements of potassium-feldspar (K-feldspar), both infrared (IR) and blue light (BL) can be used as stimulation sources. Component analysis suggests that the blue light stimulated luminescence (BLSL) measured at 60 °C from K-feldspar can be fitted using three components, namely fast, medium and slow. In order to explore the relationship between the origin of the infrared stimulated luminescence (IRSL) signal and the different components of the BLSL, five sets of experiments were conducted, namely post-IR BLSL (pIR-BLSL), post-BL IRSL (pBL-IRSL), pulse annealing tests, dose response and laboratory fading rate tests. It is observed that most of the IRSL ...


Holocene Environmental Changes In Central Inner Mongolia Revealed By Luminescence Dating Of Sediments From The Sala Us River Valley, Sheng-Hua Li, Jimin Sun, Bo Li Jan 2012

Holocene Environmental Changes In Central Inner Mongolia Revealed By Luminescence Dating Of Sediments From The Sala Us River Valley, Sheng-Hua Li, Jimin Sun, Bo Li

Faculty of Science, Medicine and Health - Papers: part A

Luminescence dating of the fluvial and lacustrine sediments from the Sala Us River valley at the south edge of the Mu Us Desert, central Inner Mongolia, is reported. The study region lies in the northwestern marginal zone of the east Asian summer monsoon and is sensitive to climate change. The dating results combined with environmental proxies indicate that the Holocene Climate Optimum period, took place from 8.5 to 5 ka ago and was marked by lake development. After ~5 ka ago, the region became arid, as inferred from lake regression and fluvial activity. Deposition of fluvial sediments lasted from ...


Determining The Cooling Age Using Luminescence-Thermochronology, Bo Li, Sheng-Hua Li Jan 2012

Determining The Cooling Age Using Luminescence-Thermochronology, Bo Li, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

Luminescence technique has been shown to have great potential in low-temperature (< 100 °C) themochronology. This study investigates the kinetic process of luminescence in a cooling system. We present a new formula that can be used for determining the cooling age based on luminescence-thermochronology. The cooling rate can be obtained directly from a plot of luminescence age versus the present temperature. We show that the application and capacity of luminescence-thermochronology are significantly controlled by the saturation of luminescence and environmental dose rate.

Archaeological Science In Australia: Integrating Across Disciplines And Scales Of Analysis, Zenobia Jacobs

Faculty of Science, Medicine and Health - Papers: part A

The basic questions in prehistoric archaeology have not changed much over the last forty years. In Australia, we continue to debate when and where Australia and its arid interior were first colonised, and whether or not these early colonisers were responsible for the extinction of the Australian megafauna. These questions are broad and any answers involve interdisciplinary teamwork that crosses conventional academic boundaries - the humanities and sciences.


Approximating The Face Of 'Aunty': A Question Of Likeness, Susan Hayes, Hallie Buckley, Richard Bradley, Nick Milne, John Dennison Jan 2012

Approximating The Face Of 'Aunty': A Question Of Likeness, Susan Hayes, Hallie Buckley, Richard Bradley, Nick Milne, John Dennison

Faculty of Science, Medicine and Health - Papers: part A

This paper describes two approaches to the facial approximation of three individuals from the Wairau Bar burial site (New Zealand). Two individuals were approximated working in direct reference to the remains and incorporated manual drafting. The third individual, 'Aunty' (the respectful title given by the iwi Rangitane elders) was approximated from CT scans and using computer graphics. The computer graphic approach enabled a greater level of precision in the application of the research and recommendations that inform a facial approximation, and facilitated collaboration with appropriate expertise. The computer-graphic approach, however, also resulted in a more photographic facial appearance, which can ...

Extracting Storm-Surge Data From Coastal Dunes For Improved Assessment Of Flood Risk, Alastair C. Cunningham, Marcel A. J Bakker, Sytze Van Heteren, Bert Van Der Valk, Ad J. F Van Der Spek, Dennis R. Schaart, Jakob Wallinga

Faculty of Science, Medicine and Health - Papers: part A

Future changes in climate and sea level are likely to increase the threat from storm surges in many coastal regions. Mitigation of this threat requires an understanding of storm surge magnitude and frequency, and the relationship of these variables to climate parameters. This understanding is currently limited by the brevity of instrumental records, which rarely predate the twentieth century. However, evidence of former storm surges can be recorded in coastal dunes, because the dune topography may trap high-magnitude deposits at elevated locations. Here we combine a range of techniques to extract storm-surge data from coastal dune sediment. The sediment is ...

Faculty of Science, Medicine and Health - Papers: part A

Chaîne opératoire, as both an analytical approach and a sociotechnical perspective, has had a presence in material culture literature for some considerable time. However despite the longevity of the concept, its full potential for the comparative study of material culture production and consumption has not really been realized within archaeology. Here, Farbstein explores this area through looking at the production of mobiliary art in a range of raw materials at Pavlovian Upper Paleolithic sites.


Expectations Of Scatter In Equivalent-Dose Distributions When Using Multi-Grain Aliquots For Osl Dating, Alastair C. Cunningham, Jakob Wallinga, Philip S. J Minderhoud Jan 2011

Expectations Of Scatter In Equivalent-Dose Distributions When Using Multi-Grain Aliquots For Osl Dating, Alastair C. Cunningham, Jakob Wallinga, Philip S. J Minderhoud

Faculty of Science, Medicine and Health - Papers: part A

In the OSL dating of sediment, the scatter in equivalent dose (D e) between grains is almost always larger than would be expected due to counting statistics alone. Some scatter may be caused by insufficient (partial) bleaching of some of the grains prior to deposition. In order to date partially bleached sediment, it is essential to estimate the amount of scatter caused by other processes (e.g. grain-to-grain variability in the natural dose rate). Measurements of such scatter are performed at the single-grain level; by contrast, most OSL dating is performed on multi-grain subsamples, for which grain-to-grain scatter is reduced ...
