Most of Australia's largest mammals became extinct 50,000 to 45,000 years ago, shortly after humans colonized the continent. Without exceptional climate change at that time, a human cause is inferred, but a mechanism remains elusive. 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. We speculate that… 
Fifty millennia of catastrophic extinctions after human contact.
The Aftermath of Megafaunal Extinction: Ecosystem Transformation in Pleistocene Australia
A high-resolution 130,000-year environmental record is used to resolve the cause and reconstruct the ecological consequences of extinction of Australia’s megafauna, suggesting that human arrival rather than climate caused megafaunal extinction, which then triggered replacement of mixed rainforest by sclerophyll vegetation.
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.
The Remaking of Australia's Ecology
Human occupation of Australia became widespread around 45,000 years ago. What role did humans play in the extinction of many of Australia9s large herbivores, which disappeared around the same time?
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.
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.

New Ages for the Last Australian Megafauna: Continent-Wide Extinction About 46,000 Years Ago
This work reports burial ages for megafauna from 28 sites and infer extinction across the continent around 46,400 years ago, ruling out extreme aridity at the Last Glacial Maximum as the cause of extinction, but not other climatic impacts; a "blitzkrieg" model of human-induced extinction; or an extended period of anthropogenic ecosystem disruption.
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.
Extinctions of herbivorous mammals in the late Pleistocene of Australia in relation to their feeding ecology: No evidence for environmental change as cause of extinction
It is shown that in both browsers and grazers the probability of extinction was very strongly related to body mass, and the body mass at which extinction became likely was similar in the two groups.
65,000 years of vegetation change in central australia and the australian summer monsoon
Carbon isotopes in fossil emu (Dromaius novaehollandiae) eggshell from Lake Eyre, South Australia, demonstrate that the relative abundance of C4 grasses varied substantially during the past 65,000 years, implying that the Australian monsoon was most effective between 45,000 and 65, thousands years ago and least effective during the Last Glacial Maximum.

Long palynological records from continental deposits may be divided into two categories: detailed sequences seldom extending back much further than the most recent interglacial1–3, and more
Causes and consequences of long-term climatic variability on the Australian continent
1. Ice-volume forced glacial-interglacial cyclicity is the major cause of global climate variation within the late Quaternary period. Within the Australian region, this variation is expressed
New ages for human occupation and climatic change at Lake Mungo, Australia
A new chronology corrects previous estimates for human burials at this important site and provides a new picture of Homo sapiens adapting to deteriorating climate in the world's driest inhabited continent.
Redating the onset of burning at Lynch's Crater (North Queensland): implications for human settlement in Australia
Lynch's Crater preserves a continuous, high‐resolution record of environmental changes in north Queensland. This record suggests a marked increase in burning that appears to be independent of any
