Southeastern Asia, the East Indies, and Australia showing area within approximately 600 feet of sea level

Southeastern Asia, the East Indies, and Australia showing area within approximately 600 feet of sea level. During the stages of maximum glacial accumulation, these tracts were laid bare and became routesd of travel between what are now islands. This explains the presence of rhinoceros in Java and of many large fossil mammals on other islands. New Guinea and Australia were connected and their plants and animals are similar. The deep water between Australia and the large islands to the northwest has effectively halted the passage of most plants and animals. Present land areas are shown in grey, oceans deeper than about 600 feet in black, and shallowly submerged areas in white (Stokes, 1960, p. 406).
