Figure 1 in Evidence from mitochondrial genomics supports the lower Mesozoic of South Asia as the time and place of basal divergence of cypriniform fishes (Actinopterygii: Ostariophysi)

Figure 1. Geographical regions of cypriniform fish distribution at the continental scale. The seven region scheme presented here [Africa (Af), South Asia (Sa), East Asia (Ea), Europe (Eu), Siberia (Sb), and western and eastern North America (Wn & En)] is a modification of the conventional Wallace's six region system (Berra, 2001). East Asia, Europe, and Siberia are subdivisions of the Palaearctic region, overlapping with each other. Western and eastern North America are subdivisions of the Nearctic region.
