Fig. 1: Map of Sahul (Australia and New Guinea) showing the distribution of reliably-dated megafauna sites within MIS 3 (57–29 ka) and locations mentioned in the text.
From: Extinction of eastern Sahul megafauna coincides with sustained environmental deterioration
Red star indicates South Walker Creek. a The Fitzroy River Basin (FRB). b The Lake Eyre Basin (LEB). c The northern Darling and d southern Murray River catchments of the Murray-Darling Basin (MDB). e Over three quarters of the continental area of Sahul is missing reliably-dated sites from MIS 3, here indicated north of the dashed line. Other localities mentioned in text, 1. ODP 820, 2. Lynch’s Crater, 3. Capricorn Caves, 4. North Stradbroke Island, 5. Kati Thanda–Lake Eyre, 6. Ned’s Gully, 7. Cuddie Springs, 8. Lake Mungo, 9. Mt. Cripps, 10. Titan’s Shelter, 11. Tight Entrance Cave, 12. Kudjal Yolgah Cave, 13. Kenniff Cave, 14. Gledswood Shelter and 15. Ngarrabullgan. Blue arrows indicate catchment flow direction. bmsl = below mean present day sea level indicating outline of the Sahul continent.
