Fig. 3 in Climate Relicts: Asian Scorpion Family Pseudochactidae Survived Miocene Aridification in Caves of the Annamite Mountains

Fig. 3. Estimation of divergence times (A) in evolution of the relictual Asian scorpion family Pseudochactidae Gromov 1998 with palaeogeographical reconstructions (B) indicating tectonic positions and past and present plate boundaries. Geological time periods on phylogeny include Devonian, Carboniferous, Permian,Triassic, Jurassic, Cretaceous, and Cenozoic. Divergence ages (in millions of years) plotted on phylogeny. Circled numbers denote three divergence events leading to Pseudochactidae and its three subfamilies.Timeline for origins, dispersal, and diversification of Pseudochactidae as follows: Carboniferous (340 Ma), Pseudochactidae originates near Tajik block (colored grey area), situated among chain of continental blocks and island arcs between Turkestan and Palaeo-Tethys Oceans. Jurassic–Triassic Boundary (202 Ma): Cimmerian continent collides with Eurasia and Indochina in the Jurassic, allowing ancestor of
