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
Origin of jaws - the greatest unsolved mystery of early vertebrate evolution. The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton. Innovative 3D X-ray ....Origin of jaws - the greatest unsolved mystery of early vertebrate evolution. The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton. Innovative 3D X-ray computer tomography, and the Australian synchrotron, will be used to investigate ancient cells and preserved soft tissue structures, to search for evidence that copulation and internal fertilization, as in modern mammals, might have originated when jaws first evolved.

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
