Up To Half Million People Once Lived on Now-Submerged Northwest Shelf of Sahul

Map of Sahul showing the extent of the now-submerged continental shelf (dark gray), with the area of the Northwest Shelf demarcated by a dashed black box, and the present-day distribution of the Köppen climate groups (seasonal precipitation and temperature) showing the extent of modern-day Australia and New Guinea. The tropical distribution of Late Pleistocene sites containing early axe technology are shown as black circles, sites without early axe technology as gray circles, and sites demonstrating Late Pleistocene occupation of the now submerged continental shelves as white circles.

The new-submerged Northwest Shelf of Sahul — the combined landmass of Australia and New Guinea at times of lower sea level — was a vast area of land in the Late Pleistocene epoch that connected the Australian regions of the Kimberley and western Arnhem Land during times of lower sea level than today. Map of Sahul showing the extent of the now-submerged continental shelf (dark gray), with the area of the Northwest Shelf demarcated by a...

This ancient brick from the Slemani Museum dates to the reign of Nebuchadnezzar II (ca. 604 to 562 BCE) based on the interpretation of the inscription; this object was looted from its original context before being acquired by the Slemani Museum and stored in that museum with agreement from the central government.

Sketch of a Rydberg molecule (a): the coordinates of the Rydberg electron (blue) and ground state atom (green) relative to the Rydberg core (red) are denoted with black arrows; the relevant spins are that of the Rydberg electron s1, the electron of the ground state atom s2 and the nuclear spin of the ground state atom I. Sketch of a trilobite molecule (b): the Rydberg core and the ground state atom are shown (with exaggerated size) as red and green spheres respectively; the electronic probability density projected to 2D is indicated by the density of blue dots.
