The rise of algae and the emergence of animals. This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems.

This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems. The expected outcomes include new knowledge about our own origins and the events that led to the emergence of the first animals. Additionally, new insights about the mechanisms that generated the oldest hydrocarbon reserves may lead to a new biomarker tool to aid discovery of major new oil or gas reserves in Australia’s Red Centre.Read moreRead less
Naracoorte caves: a critical window on faunal extinctions and past climates. This project aims to establish an unprecedented record of biodiversity and environmental change at Australia’s richest Quaternary fossil site – Naracoorte Caves. The study will integrate all aspects of the preserved deposits, employing new approaches in geochronology, palaeontology and geochemistry to develop truly comprehensive palaeoecological and palaeoclimate histories. This project will establish a benchmark datase ....Naracoorte caves: a critical window on faunal extinctions and past climates. This project aims to establish an unprecedented record of biodiversity and environmental change at Australia’s richest Quaternary fossil site – Naracoorte Caves. The study will integrate all aspects of the preserved deposits, employing new approaches in geochronology, palaeontology and geochemistry to develop truly comprehensive palaeoecological and palaeoclimate histories. This project will establish a benchmark dataset on past ecological and environmental change, strengthening scientific innovation in key research priority areas. It will have significant implications for understanding megafauna extinctions and past biodiversity responses, and will inform future conservation and climate change adaptation strategies. The project will transform the scientific profile of Naracoorte Caves, ensuring socioeconomic benefits to regional communities through education, ecotourism and knowledge marketing.Read moreRead less
Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeologi ....Global patterns of mammalian biodiversity loss over the last 50,000 years. Wild mammals have experienced major population losses and extinctions in recent centuries, but their communities had already suffered from widespread losses during the Pleistocene. Existing literature has focused on documenting individual extinctions or continental-scale patterns. This project aims to show how biodiversity loss played out at the local scale around the world. It will use palaeontological and zooarchaeological data to show how losses varied in space, how population sizes changed, and how species attributes such as rarity and body size related to loss. The world of mammals has become more homogeneous as biodiversity has declined. The challenge is to show how that happened across space and time.
