The Quaternary period saw the extinctions of numerous predominantly larger, especially megafaunal, species, many of which occurred during the transition from the Pleistocene to the Holocene epoch. However, the extinction wave did not stop at the end of the Pleistocene, but continued especially on isolated Islands in Holocene extinctions. Among the main causes hypothesized by paleontologists are natural climate change and overkill by humans, who appeared during the Middle Pleistocene and migrated to many regions of the world during the Late Pleistocene and Holocene. A variant of the latter possibility is the second-order predation hypothesis, which focuses more on the indirect damage caused by overcompetition with nonhuman predators. The spread of disease is also discussed as a possible reason.

Five men lifted Lyuba from her storage box. Hands sheathed in white gloves, they gingerly raised the 42,000-year-old remains of the woolly mammoth calf at a storage facility in Chai Wan yesterday.
'She feels hard, not soft at all,' said Thomas Yuen, the managing director of Michelle Art Services, who is more used to handling works of art than mummified corpses.11 Apr 2012 - 12:00am
The woolly mammoths that lived in the cold Pleistocene era may have helped humans to survive the Ice Age, but they paid a high price for it: their own extinction.
Now, the 'unselfish' extinct mammoth may help us again.
First of all let's ask: how could these 'elephants' survive the cold?30 Oct 2011 - 12:00am
A woolly rhinoceros fossil dug up by a team of Chinese and American scientists is believed to be the oldest of its kind yet found. It was found on the Tibetan Plateau.
The find has led researchers to think that some giants such as woolly mammoths, great sloths and sabre-tooth cats may have evolved in highlands before the Ice Age.14 Sep 2011 - 12:00am
A woolly rhinoceros fossil dug up by a team of Chinese and American palaeontologists on the Tibetan Plateau is believed to be the oldest specimen of its kind yet found.

Archaeologists say they may have finally solved one of Australian's biggest puzzles - how its giant prehistoric animals, collectively known as megafauna, were driven to extinction.2 Oct 2003 - 12:00am
Extinct: The Sabre-Toothed Tiger
With 15-centimetre long teeth, the Smilodon Fatalis or sabre-toothed tiger was one of the most savage and merciless killing machines to have stalked the Earth. But why did they die out? Could these ruthless predators simply have run out of prey?
