Figure 4 in An investigation into the cladistic relationships and monophyly of therocephalian therapsids (Amniota: Synapsida)

Figure 4. Temporal distribution and diversification of therocephalian therapsids during the Late Permian and Early Triassic (standardized to the stratigraphy of the Beaufort Group, Karoo Supergroup, southern Africa). Taxon sampling and tree topology are from the consensus tree illustrated in Figure 3. Broken lines indicate uncertain ranges. Temporal distributions are largely reconstructed from Rubidge (1995), Ward et al. (2005) and Abdala et al. (2008).
