This project aims to develop a robust time scale for the known aboriginal rock art sequence in the Kimberley, Western Australia (WA). The project will use new knowledge of complex processes on sandstone surfaces across the north Kimberley, and an innovative combination of four scientific dating methods developed through our earlier work. The project expects to provide a well-dated sequence for Kimberley rock art based on replication of results, confirmation across different methods, and a large interdisciplinary data set. The project will allow rigorous analysis of the relationship between dating results and rock art styles that has not previously been possible, and give new insights into Australia’s deep indigenous heritage. This will have a significant impact for future efforts in rock art conservation, and lay a foundation for cultural tourism, with important benefits for the local economy and health of regional indigenous communities.Read moreRead less

Summary
Luminescence dating of Middle Pleistocene human histories in Europe. This project aims to ascertain the timing, context and nature of early human evolution and associated cultural turnovers in southern Europe using cutting-edge dating techniques. The project plans to use recent advances in extended-range luminescence dating to establish unequivocal, multifaceted chronologies for a comprehensive range of human fossil and stone tool sites from the Iberian Peninsula. The outcomes of this project ar ....Luminescence dating of Middle Pleistocene human histories in Europe. This project aims to ascertain the timing, context and nature of early human evolution and associated cultural turnovers in southern Europe using cutting-edge dating techniques. The project plans to use recent advances in extended-range luminescence dating to establish unequivocal, multifaceted chronologies for a comprehensive range of human fossil and stone tool sites from the Iberian Peninsula. The outcomes of this project are expected to advance our understanding of early human history by providing a critical temporal reappraisal of modelled hominin evolutionary relationships, determining the mode and tempo of cultural turnovers, and unravelling how past human populations responded to major climate change and environmental pressures.Read moreRead less
Next-generation luminescence dating techniques for Earth and archaeological science applications. Chronology is a critical component of geological and archaeological studies. To reconstruct the evolutionary histories of Homo sapiens and other hominin species in their environmental context, we must establish reliable age estimates for key archaeological sites and Quaternary deposits.

Chronology is a critical component of geological and archaeological studies. To reconstruct the evolutionary histories of Homo sapiens and other hominin species in their environmental context, we must establish reliable age estimates for key archaeological sites and Quaternary deposits. This project aims to develop new-generation sediment dating techniques using the non-fading infrared stimulated luminescence (IRSL) signal from potassium feldspars. These improved methods will be able to be applied to sites in Africa, Europe and Asia that contain important human fossils and artefacts, including the unique type localities of ‘Denisovans’ and ‘Hobbits’, to answer fundamental questions about the timing of key turning points in human evolution and dispersal.Read moreRead less
Life and death of Australopithicus sediba: how a potential ancestor ended up dead in a cave in a world heritage site in South Africa. In August 2008 the remarkable Malapa fossil site was discovered with remains of the first and only fossils of Australopithecus sediba, a potential direct human ancestor. The fossils are in an exceptional state of preservation, and excavations will start in late 2013, creating a unique opportunity to develop a detailed understanding of the chemical, physical and bi ....Life and death of Australopithicus sediba: how a potential ancestor ended up dead in a cave in a world heritage site in South Africa. In August 2008 the remarkable Malapa fossil site was discovered with remains of the first and only fossils of Australopithecus sediba, a potential direct human ancestor. The fossils are in an exceptional state of preservation, and excavations will start in late 2013, creating a unique opportunity to develop a detailed understanding of the chemical, physical and biological factors that led to burial and fossilisation. This research will focus on the complex interplay between termites, sediment chemistry, landscape conditions and palaeo-climate as contributing factors to fossil preservation. The results will document the environment in which sediba lived and died, and assist future exploration for hominid fossils.Read moreRead less
The Eocene high latitude Australasian 'tropics' in a changing climate: resolving conflicting evidence. Between 45 to 30 million years ago, high latitude subtropical floras in Australia and New Zealand experienced significant climate change, leading to the evolution of present day vegetation. Understanding the effects of this climate change on extinction and speciation will produce more accurate predictions about modern floras when faced with climate change.

Island resilience to tropical cyclones and rising sea levels. This project aims to produce a dynamic model to address the global problem of low-lying island inundation following high-energy events, such as tropical cyclones and storm surges. These events threaten coastal habitats and biodiversity, and in worst cases, displace human populations. The model will identify islands at risk to inundation thereby enabling governments to adopt appropriate mitigation and/or adaptation strategies to impr ....Island resilience to tropical cyclones and rising sea levels.

New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycl ....New tools for old rocks: first cycle provenance information. The aims of this research are to enhance stratigraphic understanding of sedimentary sequences in Western Australia through application of novel provenance fingerprinting tools in K-feldspar (Pb isotopes) & apatite (U-Pb, Sr isotopes and grain chemistry). While much stratigraphic characterization has been based on detrital zircon ages & their correlation to basement sources, two major limitations are apparent: a) zircon may be multicycle, blurring source-sink relationships, b) zircon may be absent in mafic lithologies thus biasing investigations. In this work K-feldspar & apatite provenance investigation will be undertaken on a state wide basis and include case studies in the Yilgarn Craton and Canning & Northern Carnarvon Basins.

Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this ....Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.Read moreRead less
