Fig. 4

Lineage through time (LTT) plots of modern dasyuromorphians compared with global temperature and thylacinid diversity. The diversity curves were plotted based on the post-burn-in trees from the “TipNodeCalib1” total evidence tip-and-node dating analysis (see Fig. 3 and text). The black line represents the median diversity curve for modern dasyuromorphians as a whole, with the grey shading representing the 95% confidence interval (based on the post-burn-in trees). The red line represents estimated global surface temperature (taken from Hansen et al. 2013). Arrow 1 indicates the middle Miocene Climatic Optimum (MMCO), arrow 2 the middle Miocene Climatic Transition (MMCT), and arrow 3 the major increase in grass pollen seen in the palynological record of Australia (see Martin and McMinn, 1994: Fig. 2). The upper bar graph represents thylacinid generic diversity through time based on named genera (note that Mutpuracinus was not included, based on our results – see Figs 1, 2, 3), with five temporal bins used: late Oligocene (28.1–23.03 MYA), early Miocene (23.03–15.97 MYA), middle Miocene (15.97–11.62 MYA), late Miocene (11.62–5.333 MYA), Pliocene (5.333–2.58 MYA) and Quaternary (2.58–0 MYA)
