in Europe and non-tropical regions of Asia, it petered out in steps between 50,000 and 15,000 years ago, when the straight tusked elephants, woolly mammoths, rhinos and other great beasts of the
Pleistocene epoch vanished ...
The horse evolved in North America, but became extinct during the last
Pleistocene epoch, which was a long time ago.
During the late
Pleistocene Epoch about 10,000 years ago, the climate became drier and these interconnected lakes disappeared.
However, most agree that humans first arrived during several periods at the end of the
Pleistocene epoch, which began approximately 1.6 million years ago and ended around 10,000 years ago.
Pleistocene Epoch mammoths, Mammuthus, coexisted with Elephas and Loxodonta groups, to which today's Asian and African elephants belong respectively.
Because it is well established that the
Pleistocene epoch was a period of intense climatic fluctuation, there is a widespread tendency among biologists to assume that the current geographic distribution of most terrestrial organisms has been determined primarily by Pleistocene events (e.g., Orr 1960; Savage 1960; Findley 1969; Hubbard 1973; Morafka 1974; Schmidly et al.
To understand the natural history of glaciers, you need to go back 2 million years, to the start of the
Pleistocene epoch. Since that geologic era began, there have been dozens of ice ages, each lasting about 100,000 years, punctuated by periods of warming.
Rodham-Clinton was the most undiluted form of chivalry witnessed since the
Pleistocene epoch.
Edward Stilson's June 28 letter on climate change was informative and I benefited from his scholarly tutorial on the
Pleistocene Epoch, interstadial periods, the anthropogenic effect, ocean currents and trigger events.
The first preserved leafcutter bees from the
Pleistocene epoch have turned up in the La Brea Tar Pits in Los Angeles.
