Rapid climatic change at the beginning of the Oligocene epoch is concordant with global biotic turnover in the fossil record. However, while Southern Hemisphere geological movement played a key role in shaping these global climatic shifts, given generally poor terrestrial fossil records, evidence for matching turnover in entire Austral biotas is lacking. Emerging comprehensive phylogenetic frameworks provide alternative avenues to explore for signals of mass turnover or restructuring. Here, we combine phylogenetic data with empirical and simulation-based approaches to understand the temporal dynamics of the origins of a diverse and highly endemic continental biota (Australian lizards and sna..View full abstract
