Biogeography and evolution of Australia's fossil reptiles: A global perspective. Large marine reptiles such as plesiosaurs, and missing links such as legged snakes, are spectacular animals that have captured public attention. This collaboration will directly enhance public museum displays by collecting and preparing these spectacular fossils; many of the fossils found by the CIs are now centerpieces of museum displays (e.g. the SA museum).

Large marine reptiles such as plesiosaurs, and missing links such as legged snakes, are spectacular animals that have captured public attention. This collaboration will directly enhance public museum displays by collecting and preparing these spectacular fossils; many of the fossils found by the CIs are now centerpieces of museum displays (e.g. the SA museum). Also, it will also promote awareness and sustainable use of the environment: it will facilitate CI Kear in running earthwatch-style ecotourism field trips which promote sustainable use of finite fossil resources by making them commercially valuable to local communities as a source of tourism revenue.Read moreRead less
Overturning the Ediacara biota: community structure of the oldest animal ecosystems. The first systematic excavation of serial fossil beds of South Australia's famous Ediacara biota will lead to an integrated study of the oldest diverse macroscopic assemblages of life on Earth. Once the preservational and biological components of the record have been separated, Ediacaran fossil beds can be treated as 'snap-shots? of benthic marine communities. This will enable the use of palaeoecological tools t ....Overturning the Ediacara biota: community structure of the oldest animal ecosystems. The first systematic excavation of serial fossil beds of South Australia's famous Ediacara biota will lead to an integrated study of the oldest diverse macroscopic assemblages of life on Earth. Once the preservational and biological components of the record have been separated, Ediacaran fossil beds can be treated as 'snap-shots? of benthic marine communities. This will enable the use of palaeoecological tools to determine which if any of these Precambrian fossils were members of animal groups that heralded the Cambrian explosion of animal life.Read moreRead less
Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media ....Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media. This project raises awareness about sustainable use of non-renewable fossil resources through public education and ecotourism fieldwork programs; these will help generate local interest and thus protection of sensitive fossil localities by highlighting them as lucrative tourism assets for regional communities.Read moreRead less
The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges ....The Cambrian Population Explosion of Arthropods in Australia: Ediacaran origins, evolution and biodiversity. This project addresses key questions on the origin and diversification of life, by investigating the evolution of the most important fossil group (arthropods) across arguably the most important event after the origin of life (the Cambrian explosion of macroscopic life). It will also excavate, promote and conserve two key geological resources of national importance, in the Flinders Ranges and Kangaroo Island. Also, it will lead to increased knowledge of the palaeoecology and geology of the economically-important Adelaide geosyncline, and benefit rural SA communities through ecotourism, a rural schools education program, and public outreach.Read moreRead less
Australian fossil marine reptiles: a research and regional museum program. Australian Mesozoic marine reptile fossils are common but poorly studied. Two of the most productive localities - Richmond QLD, Coober Pedy SA - are internationally important, spanning a poorly known stratigraphic interval of marine reptile evolution and representing a high-latitude geographic region subject to near freezing conditions. Such preservation occurs nowhere else and provides a unique opportunity for anatomical ....Australian fossil marine reptiles: a research and regional museum program. Australian Mesozoic marine reptile fossils are common but poorly studied. Two of the most productive localities - Richmond QLD, Coober Pedy SA - are internationally important, spanning a poorly known stratigraphic interval of marine reptile evolution and representing a high-latitude geographic region subject to near freezing conditions. Such preservation occurs nowhere else and provides a unique opportunity for anatomical, systematic and palaeobiological investigations. Such research benefits local communities because it forms the basis for regional museum displays, generates long-term tourism revenue, and encourages geological resources to be viewed as valuable natural assets to be responsibly managed for the future.Read moreRead less
Evolutionary dynamics in deep time: faunal turnover during the Ediacaran. This project aims to investigate the world’s oldest faunal succession in the fossil record by determining the presence and extent of a sedimentary gap and confirming the role of time in the control of fossil distribution. Significant breakthroughs and capacity building are expected in the areas of palaeontology, evolutionary biology and geology using a hitherto unrecognised hiatus in the rock succession. Project outcomes i ....Evolutionary dynamics in deep time: faunal turnover during the Ediacaran. This project aims to investigate the world’s oldest faunal succession in the fossil record by determining the presence and extent of a sedimentary gap and confirming the role of time in the control of fossil distribution. Significant breakthroughs and capacity building are expected in the areas of palaeontology, evolutionary biology and geology using a hitherto unrecognised hiatus in the rock succession. Project outcomes include enhanced understanding of the first animal communities on Earth – these should provide significant benefits, such as revealing Australia's unique record of oldest complex organisms, while bringing additional tourism to the region, and increasing the strength of the Flinders Ranges UNESCO World Heritage nomination.Read moreRead less

Summary
Out of China? Australia's earliest endemic jawed vertebrate faunas. This project will seek new fossil discoveries from Australian Devonian sediments to address questions of the origins, diversification and biogeographical dispersal of early jawed vertebrates. In particular, there is the potential to test or refine recent evolutionary hypotheses based on fossil finds from the Siluro-Devonian of southern China which served as a likely point of origin for several key vertebrate groups. Likely finds ....Out of China? Australia's earliest endemic jawed vertebrate faunas. This project will seek new fossil discoveries from Australian Devonian sediments to address questions of the origins, diversification and biogeographical dispersal of early jawed vertebrates. In particular, there is the potential to test or refine recent evolutionary hypotheses based on fossil finds from the Siluro-Devonian of southern China which served as a likely point of origin for several key vertebrate groups. Likely finds include fishes that test dermal bone-homologies between osteichthyans and placoderms, jawless fishes that may unveil details of the origin of jaws, and calibration of paleoatmospheric models via the observed size of Early Devonian fossil fishes.Read moreRead less
