Lost landmass, once home to 500,000 people, discovered under the sea
A, now-submerged, continental shelf landmass, covering some 390,000 square kilometres (±242,300 sq. miles], which was once home to up to half a million people, has been discovered [1], off the coast of northern Australia.
This archipelago, covering an area larger than New Zealand, appeared between 70,000 and 61,000 years ago, and remained stable for about 9,000 years.
With descent into the last Ice Age, polar ice caps grew and sea levels dropped, by up to 120 meters. This fully exposed the shelf, for the first time in 100,000 years.
When the last Ice Age ended, around 18,000 years ago, global warming caused sea levels to rise, which drowned out swathes of the world's continents.
This split the supercontinent of Sahul into New Guinea and
Australia, and cut Tasmania off from the mainland.
The region contained a mosaic of habitable fresh, and saltwater environments. The most salient of these features was the Malita inland sea.
This sea existed for 10,000 years [27,000 to 17,000 years ago], with a surface area greater than 18,000 square kilometres, according to the archaeologists.
