Toppling the Boring Billion: Biomarkers, orbital cycles and primordial life. This project aims to discover microbiological processes involved in ore formation in order to understand how zinc and lead minerals formed in the sediments of Australia’s ancient seas. The apparent ‘Boring Billion’ – the geological period 1800 to 800 million years ago – may have harboured seas of fluctuating colours.

This project aims to discover microbiological processes involved in ore formation in order to understand how zinc and lead minerals formed in the sediments of Australia’s ancient seas. The apparent ‘Boring Billion’ – the geological period 1800 to 800 million years ago – may have harboured seas of fluctuating colours. Fossil biomolecules, unearthed from 1.6 billion years old sediments, draw a picture of ancient seas oscillating between blooms of purple and green bacteria, with waters rapidly alternating between toxic and sulphidic and rich in dissolved iron. Based on these observations, the project aims to discover the dynamic nature of primordial ecosystems, investigate how ancient seas were controlled by the Earth’s orbit around the sun, and explore how microorganisms may have formed the world’s largest zinc deposits.Read moreRead less
The rise of algae and the emergence of animals. This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems. The expected outcomes include new knowledge about our own origins and the ev ....The rise of algae and the emergence of animals. This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems. The expected outcomes include new knowledge about our own origins and the events that led to the emergence of the first animals. Additionally, new insights about the mechanisms that generated the oldest hydrocarbon reserves may lead to a new biomarker tool to aid discovery of major new oil or gas reserves in Australia’s Red Centre.Read moreRead less
Molecular traces of our primordial ancestors. This project aims to work with the exploration industry to develop an age-diagnostic fingerprinting tool for ancient petroleum seeps. Primordial molecules extracted from 1.6 billion years old rocks are the first and only witnesses of this extinct world. Australia’s vast red centre retains undiscovered oil reserves. This project will yield information about an oil’s provenance and help predict where reserves may be hidden, increasing the accuracy of s ....Molecular traces of our primordial ancestors. This project aims to work with the exploration industry to develop an age-diagnostic fingerprinting tool for ancient petroleum seeps. Primordial molecules extracted from 1.6 billion years old rocks are the first and only witnesses of this extinct world. Australia’s vast red centre retains undiscovered oil reserves. This project will yield information about an oil’s provenance and help predict where reserves may be hidden, increasing the accuracy of surveys and reducing costs and risks of exploration. Broader benefits from the findings may change common understanding about our very earliest ancestors and their effect on the planet’s evolution.Read moreRead less

Old stalagmites, new techniques: South African palaeoclimate records linked to early human evolution. Caves in South Africa preserve a rich hominin (early human) fossil and archaeological record dating back over two million years. This project uses stalagmites from various South African caves to provide a new, detailed record of the palaeoclimate, forming the backdrop to the evolutionary changes that took place during this period.
Glauconite: Archive Recording Timing and Triggers of Cambrian Radiation . This project aims to constrain the timing and speed of the Cambrian radiation of complex animals, and to test potential environmental triggers of this milestone bioevent. New laser mass spectrometry and mineral mapping technology will be integrated to precisely date glauconite – a silicate mineral commonly formed in Cambrian shallow marine animal habitats.

This project aims to constrain the timing and speed of the Cambrian radiation of complex animals, and to test potential environmental triggers of this milestone bioevent. New laser mass spectrometry and mineral mapping technology will be integrated to precisely date glauconite – a silicate mineral commonly formed in Cambrian shallow marine animal habitats. This innovative and cost-effective approach will produce the first high-resolution timeline of early animal evolution, where the glauconite-based marine isotope record identifies the most likely environmental trigger for the Cambrian Radiation. Outcomes of this study include improved understanding of the drivers of animal evolution, and a new dating tool for basic and applied research.Read moreRead less

Improving thiocyanate bioremediation with meta-genomics/transcriptomics. This project aims to elucidate the roles of thiocyanate-degrading microbial consortium members involved in sulphur and nitrogen oxidation, using metagenomics and metatranscriptomics. The gold mining industry generates environmentally toxic thiocyanate as a waste by-product, for which the most cost-effective remediation strategy is degradation by natural microbes. Efforts to bioremediate, however, suffer from a lack of understanding of the full metabolic potential of the microbes involved. The intended outcome of this project is the improved design and operation of thiocyanate bioremediation reactor systems.Read moreRead less
Fleshing out the fossil record: using organically preserved soft tissues and bone to explore the evolution of unique vertebrate characters. This study integrates developmental, molecular and morphological data in both fossil and living species to provide insights into the evolutionary mechanisms which formed the musculo/skeletal system. Uncovering these evolutionary pathways has the potential to describe mechanisms common to all vertebrate and informs us about our own evolution.
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
