The extermination of megafauna left many niches vacant, which has been cited as an explanation for the vulnerability and fragility of many ecosystems to destruction in the later Holocene extinction. The comparative lack of megafauna in modern ecosystems has reduced high-order interactions among surviving species, reducing ecological complexity ...
New evidence based on accurate optically stimulated luminescence and uranium-thorium dating of megafaunal remains suggests that humans were the ultimate cause of the extinction for some of the megafauna in Australia. [5] [6] The dates derived show that all forms of megafauna on the Australian mainland became extinct in the same rapid timeframe ...
Megafauna also play a role in regulating and stabilizing the abundance of smaller animals. During the Pleistocene, megafauna were diverse across the globe, with most continental ecosystems exhibiting similar or greater species richness in megafauna as compared to ecosystems in Africa today.
Paleoindians lived alongside and hunted many now extinct megafauna (large animals), with most large animals across the Americas becoming extinct towards the end of the Paleoindian period as part of the Late Pleistocene megafauna extinctions. The potential role of human hunting in the extinctions has been the subject of much controversy.
One probable bullroarer is identified at Lalinde, France, dating to 14 to 12 thousand years ago, measuring 16 cm (6.3 in) long and decorated with geometric incisions. In the mammoth-bone houses at Mezine, Ukraine, an 80 cm × 20 cm (31.5 in × 7.9 in) thigh-bone, a 53 cm × 50 cm (21 in × 20 in) jawbone, a 57 cm × 63 cm (22 in × 25 in ...

In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
[218] [219] [220] Human hunting and butchery of large megafauna, particularly mammoths and mastodon, would likely have put people in competition with Arctodus simus. Defense against these large bears and the abandonment of carcasses are plausible outcomes, [ 18 ] along with the possible caching and disposal of carcass remains underwater to mask ...
