Research Themes

All Principal Investigators:

The fish/tetrapod transition and early tetrapod faunas. Early radiation of amniotes and amphibians

Research Interests

The origin, phylogeny and radiation of early tetrapods and their relatives among the lobe-finned fish. The "fish-tetrapod" transition, and the evolution of terrestriality. Timing and sequence of skeletal and other changes which occurred during the transition, and the origin and relationships of the diverse tetrapods of the Late Palaeozoic. Origins of the modern radiations of tetrapods.
