The earliest scleractinian fossils come from key sites in the former Tethys region (Stanley, 1988).During the Triassic, it was the vast warm-water, east–west trending tropical Tethys seaway that became the center of reef-building and coral diversity during much of the remaining Mesozoic (Fig. 2).(branching) coral with a tight bush-like form (figure 10).
