What caused extinction of the Pleistocene megafauna of Sahul?
During the Pleistocene, Australia and New Guinea supported a rich assemblage of large vertebrates. Why these animals disappeared has been debated for more than a century and remains controversial. Previous synthetic reviews of this problem have typically focused heavily on particular types of evidence, such as the dating of extinction and human arrival, and have frequently ignored uncertainties...
متن کاملClimate change frames debate over the extinction of megafauna in Sahul (Pleistocene Australia-New Guinea).
Around 88 large vertebrate taxa disappeared from Sahul sometime during the Pleistocene, with the majority of losses (54 taxa) clearly taking place within the last 400,000 years. The largest was the 2.8-ton browsing Diprotodon optatum, whereas the ∼100- to 130-kg marsupial lion, Thylacoleo carnifex, the world's most specialized mammalian carnivore, and Varanus priscus, the largest lizard known, ...
متن کاملDietary responses of Sahul (Pleistocene Australia–New Guinea) megafauna to climate and environmental change
—Throughout the late Quaternary, the Sahul (Pleistocene Australia–New Guinea) vertebrate fauna was dominated by a diversity of large mammals, birds, and reptiles, commonly referred to as megafauna. Since ca. 450–400Ka, approximately 88 species disappeared in Sahul, including kangaroos exceeding 200kg in size, wombat-like animals the size of hippopotamuses, flightless birds, and giant monitor li...
متن کاملComputer simulations of the extinction of megafauna
Computer simulations show that the extinction of megafauna is not correlated with the growth of human population. The population of megafauna remains constant during the nearly entire time of the rapid growth of human population. Model-generated growth of human population is also in direct conflict with the empirical evidence about the human population dynamics. Computer simulations do not supp...
متن کاملPleistocene extinction of genyornis newtoni: human impact on australian megafauna
More than 85 percent of Australian terrestrial genera with a body mass exceeding 44 kilograms became extinct in the Late Pleistocene. Although most were marsupials, the list includes the large, flightless mihirung Genyornis newtoni. More than 700 dates onGenyornis eggshells from three different climate regions document the continuous presence of Genyornis from more than 100,000 years ago until ...
