Pleistocene Epoch - Megafaunal Extinctions: The end of the Pleistocene was marked by the extinction of many genera of large mammals, including mammoths, mastodons, ground sloths, and giant beavers. The extinction event is most distinct in North America, where 32 genera of large mammals vanished during an interval of about 2,000 years, centred on 11,000 bp. On other continents, fewer genera ...
Archeologist Gary Haynes, University of Nevada Reno, and others think that the continent's first human hunters, fresh from Siberia, killed the megafauna off as they colonized the newly discovered ...

Jan 25, 2016 · For hundreds of millions of years, an abundance of large animals, the megafauna, was a prominent feature of the land and oceans. However, in the last few tens of thousands of years—a blink of an eye on many evolutionary and biogeochemical timescales—something dramatic happened to Earth’s ecology; megafauna largely disappeared from vast areas, rendered either actually or functionally ...
