Oxygenation of the oceans and the origin of animals
Grant number: DP130102240 | Funding period: 2013 - 2016
This research project will investigate newly discovered ancient reefs and fossils from the Flinders Ranges that may represent the oldest known animals on Earth. Results from the project will help understand the early evolution of animal life on Earth and will contribute to a greater appreciation of Australia's geological heritage.
