All Australian land mammals, reptiles, and birds weighing more than 100 kilograms, and six of the seven genera with a body mass of 45 to 100 kilograms, perished in the late Quaternary. The timing and causes of these extinctions remain uncertain. We report burial ages for megafauna from 28 sites and infer extinction across the continent around 46,400 years ago (95% confidence interval, 51,200 to 39,800 years ago). Our results rule out extreme aridity at the Last Glacial Maximum as the cause of… 
Ecosystem Collapse in Pleistocene Australia and a Human Role in Megafaunal Extinction
A 140,000-year record of dietary δ13C documents a permanent reduction in food sources available to the Australian emu, beginning about the time of human colonization; a change replicated at three widely separated sites and in the marsupial wombat.
Climate change not to blame for late Quaternary megafauna extinctions in Australia
This is the first comprehensive approach to incorporate uncertainty in fossil ages, extinction timing and climatology, to quantify mechanisms of prehistorical extinctions of megafaunal extinctions in the world's most controversial context.
Late Quaternary Extinctions: State of the Debate
Results from recent studies suggest that humans precipitated extinction in many parts of the globe through combined direct (hunting) and perhaps indirect (competition, habitat alteration) impacts, but that the timing and geography of extinction might have been different and the worldwide magnitude less, had not climatic change coincided with human impacts in many places.
Climate change frames debate over the extinction of megafauna in Sahul (Pleistocene Australia-New Guinea)

Mounting evidence points to the loss of most species before the peopling of Sahul and a significant role for climate change in the disappearance of the continent’s megafauna.
Last Recorded Evidence For Megafauna At Wet Cave, Naracoorte, South Australia 45,000 Years Ago
Over 85 percent of Australian terrestrial vertebrate genera with a body mass greater than 44 kg became extinct during the late Pleistocene. These included all marsupials exceeding 100 kg (1 9
Timing and dynamics of Late Pleistocene mammal extinctions in southwestern Australia
An exceptional faunal succession from Tight Entrance Cave, southwestern Australia is reported, which shows persistence of a diverse mammal community for at least 100 ka leading up to the earliest regional evidence of humans at 49 ka.
Australia's Mammal Extinctions: A 50,000-Year History
This book introduces readers to the great mammal extinction debate by taking a detective-like tour of these extinctions, uncovering how, why and when they occurred.
Humans rather than climate the primary cause of Pleistocene megafaunal extinction in Australia
A continuous 150,000-year record offshore south-western Australia is presented and it is established that substantial changes in vegetation and fire regime occurred ∼70,000 years ago under a climate much drier than today.
Late Pleistocene Megafaunal Extinctions


Pleistocene extinction of genyornis newtoni: human impact on australian megafauna
Simultaneous extinction of Genyornis at all sites during an interval of modest climate change implies that human impact, not climate, was responsible.
Subtropical North Atlantic Temperatures 60,000 to 30,000 Years Ago.

A reconstruction of sea surface temperature based on alkenone unsaturation ratios in sediments of the Bermuda Rise provides a detailed record of subtropical climate from 60,000 to 30,000 years ago, suggesting that the largest, most rapid warmings were especially unstable.

Rapid extinction of the moas (Aves: Dinornithiformes): model, test, and implications.
A Leslie matrix population model supported by carbon-14 dating of early occupation layers lacking moa remains suggests that human hunting and habitat destruction drove the 11 species of moa to
Thermoluminescence dating of a 50,000-year-old human occupation site in northern Australia
THE oldest secure date for human occupation in Greater Australia is 40kyr from eastern Papua New Guinea1, whereas slightly younger dates have been reported from southern Australia2. We now report
Australia's oldest human remains: age of the Lake Mungo 3 skeleton.
The Lake Mungo 3 burial documents the earliest known human presence on the Australian continent and implies that people who were skeletally within the range of the present Australian indigenous population colonized the continent during or before oxygen isotope stage 4 (57,000-71,000 years).
500 ka precipitation record from southeastern Australia: Evidence for interglacial relative aridity
230 Th/ 234 U dating of speleothems from southeastern Australia documents changes in effective precipitation over the past 500 k.y. at a temporal resolution not previously achieved. Results show that
Millennial-scale instability of the antarctic ice sheet during the last glaciation
Carbon isotopes of benthic foraminifers reveal that South Atlantic IRD events coincided with strong increases in North Atlantic Deep Water production and inferred warming (interstadials) in the high-latitude North Atlantic.
Early Human Occupation at Devil's Lair, Southwestern Australia 50,000 Years Ago
Abstract New dating confirms that people occupied the Australian continent before the earliest time inferred from conventional radiocarbon analysis. Many of the new ages were obtained by accelerator
Wetting and drying of Australia over the past 300 ka
Alternately dry and wet climatic episodes across central and eastern Australia during the past 300 ka have greatly affected Australia9s rivers, lakes, and dune fields. Evidence of widespread climate
