The May 2011 discovery of the oldest fossiliferous amber deposit from Australia, and all of Southern Gondwana, provides a unique opportunity to study the only recorded terrestrial biotas of this age on the continent. Employing new imaging techniques (MicroXCT-400, X-ray ultramicroscope and Synchrotron radiation), the new fossils dated as 90 million years old will be extracted virtually in three-dimensional to capture the finest details from this major palaeontological find. The outcomes of the study will attract much national and international attention as the researchers identify the first Mesozoic organisms of this age living in habitats in and close to the resin-producing forests, thus opening an entirely new window of opportunities in this field.Read moreRead less
New Insights into the Origin and Evolution of Life on Earth. This project aims to provide new insights into the origin of life on Earth, life’s diversification through the Precambrian, and the co-evolution of life and early Earth environments. It will be discipline-leading in that it will take the study of early life to the sub-micrometre and hence sub-cellular level. This will facilitate new opportunities for identifying the types of life present during early Earth history, their metabolisms, c ....New Insights into the Origin and Evolution of Life on Earth. This project aims to provide new insights into the origin of life on Earth, life’s diversification through the Precambrian, and the co-evolution of life and early Earth environments. It will be discipline-leading in that it will take the study of early life to the sub-micrometre and hence sub-cellular level. This will facilitate new opportunities for identifying the types of life present during early Earth history, their metabolisms, cellular chemistry and interactions with their environment. This project aims to also provide new search engines and more robust assessment criteria for life on other planets, and help to resolve specific scientific controversies, for example, the validity of claims for cellular life from 3.5 billion-year-old rocks.Read moreRead less
Predation as a major ecological driver of early animal evolution. This project aims to address one of the biggest questions about the early evolutionary history of complex life: was predation a driving force behind the major diversification of animals over 500 million years ago? This innovative study will extend the application of computational biomechanics and use extensive fossil collections to quantify the performance of predators and the evolutionary responses of prey species. Anticipated ou ....Predation as a major ecological driver of early animal evolution. This project aims to address one of the biggest questions about the early evolutionary history of complex life: was predation a driving force behind the major diversification of animals over 500 million years ago? This innovative study will extend the application of computational biomechanics and use extensive fossil collections to quantify the performance of predators and the evolutionary responses of prey species. Anticipated outcomes and benefits include a paradigm shift in knowledge of how predator-prey dynamics shaped the first animal ecosystems, new approaches for studying the functional morphology and microevolutionary patterns of extinct invertebrates, and highlighting the international significance of Australia’s natural heritage.Read moreRead less

Summary
Exploring the nexus between global palaeogeography and the rise of animals. The Ediacaran–Cambrian periods (635–485 million years ago) capture one of the most critical events in the history of life, but are rarely the focus of global-scale palaeogeographic modelling. By employing a holistic, multi-proxy approach that synthesises vast fossil and geological datasets, this project aims to reconstruct continental positions to determine how shifting landmasses influenced the evolution of the first co ....Exploring the nexus between global palaeogeography and the rise of animals. The Ediacaran–Cambrian periods (635–485 million years ago) capture one of the most critical events in the history of life, but are rarely the focus of global-scale palaeogeographic modelling. By employing a holistic, multi-proxy approach that synthesises vast fossil and geological datasets, this project aims to reconstruct continental positions to determine how shifting landmasses influenced the evolution of the first complex animals. Expected outcomes and benefits include a new, animated global model of continental evolution that can be used across a broad range of fields, particularly for studies investigating the development of Earth System processes and the biosphere in deep time, with potential applications in resource exploration.Read moreRead less
Early Palaeozoic radiolarian evolution. This project will apply a new transformative technology, X-ray micro computed tomography, to the study of Early Palaeozoic (530-300 million year old) radiolarian microfossils. It is expected that this will allow, for the first time, non-destructive examination to elucidate the internal skeletal architecture of these fossils that is critical to understanding their evolution.

It is expected that this will allow, for the first time, non-destructive examination to elucidate the internal skeletal architecture of these fossils that is critical to understanding their evolution. Computer reconstruction of three-dimensional images will reveal details upon which an understanding of early phylogenetic relationships within this phylum can be developed. This in turn will allow realisation of the full biostratigraphic potential of this important long-ranging group of marine protozoans that commonly occur in great abundance in deep marine sedimentary rocks.Read moreRead less
The reptile-mammal jaw transition as revealed by 3D imaging, embryology, and computational biomechanics: new approaches to some age old questions. The extraordinary transformation of the mammalian middle ear through biomechanical 're-tooling' of the ancestral reptilian jaw joint, also recapitulated in mammalian development, yielded the greatly improved feeding and hearing efficiency that are key to the mammalian success story. Building on recent methodological advances, this project will employ ....The reptile-mammal jaw transition as revealed by 3D imaging, embryology, and computational biomechanics: new approaches to some age old questions. The extraordinary transformation of the mammalian middle ear through biomechanical 're-tooling' of the ancestral reptilian jaw joint, also recapitulated in mammalian development, yielded the greatly improved feeding and hearing efficiency that are key to the mammalian success story. Building on recent methodological advances, this project will employ cutting-edge two-dimensional protocols to explain these mechanical details of this transition. This includes integration of the first undistorted embryological soft-tissue evidence for muscular arrangements in the transitioning jaw. Through vastly improving on conventional two-dimensional approaches, the project will maintain Australia's leading position in the fast developing field of virtual biomechanics.Read moreRead less

This project aims to reveal the role of diet in the spread and subsequent dominance of Mesozoic dinosaurs. Previous research has revealed much about dinosaur anatomy and diversity, but their diets remain broadly classified into two categories, herbivores and carnivores. This project will use 3D scans of dinosaur teeth to calculate anatomical indicators of diet, and interpret diet as a continuous variable which will permit unprecedented evolutionary analyses of dinosaur ecology. Anticipated outcomes include an innovative framework with which to reconstruct the ecological diversity of dinosaurs from Australia and around the world and understand the processes that led to their success for over 150 million years.Read moreRead less

Opalised fossils and the evolution of Australia's dinosaurs. This project aims to study dinosaur evolution in Australia. Dinosaurs were one of Earth's most successful land vertebrates, but Australia’s perceived poor dinosaur fossil record has stymied significant advances in the field and promoted the view that it was an evolutionary dead-end.

This project aims to study dinosaur evolution in Australia. Dinosaurs were one of Earth's most successful land vertebrates, but Australia’s perceived poor dinosaur fossil record has stymied significant advances in the field and promoted the view that it was an evolutionary dead-end. This project will challenge this perception by coupling an exceptional but under-valued fossil resource from Lightning Ridge, NSW, with new phylogenetic methodology and synchrotron analyses. The expected result is better understanding of the diversity, biology, and evolutionary relationships of Australian dinosaurs in the context of global dinosaur evolution.Read moreRead less

This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of environments, climate and life. A major outcome will be an improved understanding of how the Earth's atmosphere and climate are regulated by geological processes. This project will generate new knowledge about how sedimentary zinc, lead and copper ore deposits form, which may guide exploration for these commodities.Read moreRead less
