Determining the relative roles of dispersal and vicariance in the assembly of the New Zealand fauna. New fossils from New Zealand's St Bathans Fauna (19-16 million years) will revolutionise our understanding of the shared biodiversity and evolutionary history of New Zealand and Australia through the first views of the origin and evolution of major Gondwanan groups including frogs, crocodiles, birds and bats on the now mostly-drowned continent Zealandia.
Glauconite: Archive Recording Timing and Triggers of Cambrian Radiation . This project aims to constrain the timing and speed of the Cambrian radiation of complex animals, and to test potential environmental triggers of this milestone bioevent. New laser mass spectrometry and mineral mapping technology will be integrated to precisely date glauconite – a silicate mineral commonly formed in Cambrian shallow marine animal habitats.

This project aims to constrain the timing and speed of the Cambrian radiation of complex animals, and to test potential environmental triggers of this milestone bioevent. New laser mass spectrometry and mineral mapping technology will be integrated to precisely date glauconite – a silicate mineral commonly formed in Cambrian shallow marine animal habitats. This innovative and cost-effective approach will produce the first high-resolution timeline of early animal evolution, where the glauconite-based marine isotope record identifies the most likely environmental trigger for the Cambrian Radiation. Outcomes of this study include improved understanding of the drivers of animal evolution, and a new dating tool for basic and applied research.Read moreRead less

All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel ....All you can eat: evolution of feeding in the largest animals on Earth. This project aims to establish how Baleen whales, the largest animals on Earth and major ecosystem engineers, evolved their signature filter-feeding strategy. Unlike other mammals, whales are toothless, and instead use a keratinous, comb-like sieve to filter vast amounts of small prey from seawater. Various approaches, including biomechanics, three-dimensional imaging, geochemistry and quantitative palaeobiology will unravel how and when filter feeding emerged, how it diversified over time, and whether its evolution correlated with past environmental change. The project is expected to reveal clues on how whales became one of the greatest ecological actors in the sea, and will benefit conservation by providing a glimpse into their future.Read moreRead less

Summary
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 will challenge this perception by coupling an exceptional but under-valued fossil resource from Lightning Ridge, NSW, with new phylogenetic me ....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 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
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
Evolution, breeding biology and extinction of giant fowl in Australia and the Southwest Pacific. New investigation of the extinct giant flightless Australian mihirungs and similar giant fowl of Oceania by analysis of fossils will reveal their relationships and resolve the evolutionary history of fowl globally. This project will provide insight into breeding strategies of these fossil species and the causes and impacts of their extinction.
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.

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

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

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
