Humans, not climate change, caused the mass extinction of Australia's giant animals, such as huge kangaroos, tens of thousands of years ago. Scientists have long argued over what killed off about 50 species of animals weighing more than 45 kilograms, including the gigantic kangaroo, Procoptodon , and the two-tonne wombat-like marsupial Diprotodon , late in the Pleistocene epoch, which stretched from 2.
Early humans wiped out Australia's giants

Stegodons Stegodontidae: Proboscidea were a widespread and diverse family of proboscideans dating from the late Miocene to the Late Pleistocene of Africa and Asia. In Southeast Asia, stegodons are remarkable for being one of only a few large-bodied species to be relatively common in the fossil record of both small and large islands Van den Bergh, Moreover, the occurrence of stegodons on islands that have never been connected to continents means they were commonly the only large- or medium-sized mammals to inhabit these until the later arrival of anatomically modern humans. Genetic and geographic isolation of stegodon populations resulted in dwarfing, speciation, and extinctions, with these processes playing out on different islands at different times Van den Bergh, ; Van der Geer et al. Stegodons are thus important for understanding some key biological phenomena including the dispersal abilities of large-bodied mammals and the evolutionary mechanisms of island dwarfing. In , the archaeologist Theodore Verhoeven travelled to the island of Timor Fig. His visit was a success, as he found both stegodon molar fragments and stone tools in the vicinity of the village of Atambua, in what is now West Timor, Indonesia Verhoeven,
Sahul: Pleistocene Continent of Australia, Tasmania, and New Guinea
Sahul is the name given to the single Pleistocene-era continent which connected Australia with New Guinea and Tasmania. At the time, the sea level was as much as meters feet lower than it is today; rising sea levels created the separate landmasses we recognize. When Sahul was a single continent, many of the islands of Indonesia were joined to the South East Asian mainland in another Pleistocene era continent called "Sunda". It is important to remember that what we have today is an unusual configuration. Since the beginning of the Pleistocene , Sahul was almost always a single continent, except during those short periods between glacial expansions when the sea level rises to isolate these components into north and south Sahul.
