From 19 000 years ago, the earth transitioned out of The Pliocene Ice Age. Sea levels lowered and many land species could not adapt fast enough to survive the harsh, cold climates. The cause of this mass extinction event is thought to be the shift in the continents and drastic climate change. An ice age is a period of long-term reduction in the temperature of Earth's climate, resulting in an expansion of the continental ice sheets, polar ice sheets and mountain glaciers. Settlement 2. true. For the area that is now New York State, this meant the loss of species such as mammoth, mastodon, stag-moose, giant beaver, and giant ground sloth. We are still in the Quaternary today. Answer (1 of 5): Crocodilians are very tough creatures. Caves were essential for these Ice Age bears to hibernate during the winter months. Different theories attribute the extinction of these species to different factors, but many theories have held human activities like hunting responsible for the extinction of these species.

(As of 1968, there were 60 theories for the cause of the ice age.43 In 1957, a prominent ice age specialist, J. K. Charlesworth, summarised ice age theories: 'Pleistocene phenomena have produced an absolute riot domino-effect of all these factors is responsible for the extinction of the ice age mammals. The researchers point out that periods of dramatic climate swings characterized each Ice Age, with the most recent epoch spanning from around 110,000 to 12,000 years ago. Choose all that apply. The cause of this mass extinction event is thought to be the shift in the continents and drastic climate change. St. Paul's landscape of treeless tundra has likely changed little since the end of the last ice age, some 12,000 years ago. A woolly mammoth discovered in Siberia in 2010.
