Palaeoecosystems Research Group
A research group of the Department of Earth Sciences.
Our research focuses on the systematics and palaeoecology of fossil invertebrates. By integrating data from exceptionally-preserved macrofossils with the carbonaceous and mineralized microfossil record, we generate a phylogenetically and stratigraphically informed perspective on the changing nature of ecosystems through time, with a particular emphasis on the Lower Palaeozoic.
By addressing the fluctuating compositions, diversities and structures of ecosystems through the past billion years, we aim to understand how life has both responded to and contributed to global environmental and climatic changes. We have developed and applied a range of numerical, computer-based techniques to the description and analyses of fossils and their distributions in deep time.
Our interdisciplinary research programs, supported by an international network of collaborators, include:
- Early Palaeozoic Lagerstätten
- Palaeozoic ecosystems, including origin, diversifications and extinctions
- Reconstruction of climate in deep time
- Approaches to reconstructing evolutionary history
Our research is strongly grounded in geological fieldwork in spectacular locations ranging from the Arctic wastes of North Greenland to the roof of the world in Tibet. Our funders include the Natural Environment Research Council (NERC), Agouron Institute, the Danish Council for Independent Research, the petroleum industry, and charities.
