Sundaland: with the sea about 115 metres lower, about 2.5 million square kilometres of today’s shallow seas on this plate were dry land, nearly doubling its land, and Borneo, Sumatra, Java and the Malay Peninsula were one landmass with mainland Asia, drained by great rivers. The land was already dry when the timeline begins; the rising sea drowned most of it between 14,446 and 8,876 years ago, fastest in a meltwater pulse about 14,500 years ago.
