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.

Global implications of Australian Cretaceous faunas: biogeography, evolution and effects of climate change. Climate change is a critical issue with poorly known long-term effects. This collaboration will provide information on how marine and terrestrial faunas have responded to environmental alteration in the past.

Climate change is a critical issue with poorly known long-term effects. This collaboration will provide information on how marine and terrestrial faunas have responded to environmental alteration in the past. Mesozoic vertebrates make spectacular fossils that capture public attention. This collaboration will enhance public museum displays by collection and preparation of important new specimens; many found by the investigators are already centerpieces in major museums (e.g. SA Museum). This project will also promote awareness and sustainable use of the environment through media promotion and 'earthwatch-style' ecotourism field trips; these highlight finite fossil resources as lucrative sources of tourism revenue to regional communities.
