This project will add to our knowledge of Australian dinosaurs and the world they inhabited. Dinosaurs are often the means through which many people, especially children, are introduced to science. This project has the potential to greatly enhance this attraction to science, using the results of research on Australian dinosaurs. It has direct links with a number of national and international museum exhibitions, and in western Queensland the results will be incorporated into a newly developed regional interpretive centre in Isisford. The enormous social and economic benefits linked to this initiative will open up numerous opportunities for local businesses, and increase the appreciation for science and exploration in outback areas.Read moreRead less
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.

This collaboration will enhance public museum displays by collection and preparation of important new spec ....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. 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.

The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on trop ....The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification. This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less
Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes ....Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes. This project expects to generate new knowledge on the anatomy of the vertebrate brain with improved methods for reconstructing fossil brains to better understand our own neurological evolution. Expected outcomes include enhanced institutional collaborations within Australia, and between Australia, Canada and the USA.Read moreRead less
Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography dat ....Resolving evolutionary problems at the fish-tetrapod transition. The project aims to investigate very early Australian tetrapod trackways and conduct fieldwork to resolve the place of origin and timing of the evolution of the first tetrapods. The evolution of fishes to tetrapods was one of the key events in evolution. Studies on Northern Hemisphere fossils place an origin for the group around 380 million years ago. Australian fossils suggest a much older origin. New micro computed tomography data from Australian 3-D fossil fishes, combined with study of rare tetrapod gill arch bones, would enable us to determine the origins of tetrapod air-breathing and its ecological setting. The project may facilitate a rewriting of vertebrate evolution's most significant first step.Read moreRead less
The Devonian Gogo Fauna: Diversity, Palaeoecology and Global Significance. The late Devonian Gogo Formation (380 million years old) is undoubtedly one of the richest and best-preserved assemblages of fossil fishes and invertebrates from this age anywhere on Earth. This project will use CT scanning for stomach contents, plus use biomechanical and morphometric analyses to reconstruct tropic relationships of reef-dwelling organisms and test the resilience of the reef ecosystem. Several new species .... The Devonian Gogo Fauna: Diversity, Palaeoecology and Global Significance. The late Devonian Gogo Formation (380 million years old) is undoubtedly one of the richest and best-preserved assemblages of fossil fishes and invertebrates from this age anywhere on Earth. This project will use CT scanning for stomach contents, plus use biomechanical and morphometric analyses to reconstruct tropic relationships of reef-dwelling organisms and test the resilience of the reef ecosystem. Several new species will be published and the heritage significance of the site will be assessed. Working with local indigenous stakeholders, the scientific findings will feed into developing a long-term management plan to protect and conserve the site for future research work and to grow tourism in the region.Read moreRead less
Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mech ....Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mechanisms to ensure that managers of Australia's reefs have critical information on how past disturbance frequency and intensity has affected coral reef communities. This information will help ensure the continuation of ecosystem goods and services from Australia's high diversity coral reefs.Read moreRead less
