Reconstruction of eastern Gondwanaland for the Mid-Late Silurian showing the postulated positions of the East and Southeast Asian terranes, distribution of land and sea, and shallow-marine fossils that appear to define an Australasian province at this time. WC = Western Cimmerian Continent WB = SW Borneo. Present day outlines are for reference only. Distribution of land and sea for Chinese blocks principally from Wang (1985). Land and sea distribution for Pangea/Gondwanaland compiled from Golongka et al. (1994), Smith et al. (1994); and for Australia from Struckmeyer & Totterdell (1990).
