This is a list of Ice Age species preserved as permafrost mummies during the Late Pleistocene. It includes all known species that have had their tissues partially preserved within the permafrost layer of the Arctic and Subarctic. Most went extinct during the Late Pleistocene extinctions while some are still extant today. They have been listed ...
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
The most obvious change associated with the termination of an ice age is the increase in temperature. Between 15,000 BP and 10,000 BP, a 6 °C increase in global mean annual temperatures occurred. This was generally thought to be the cause of the extinctions.
Cave bears of the last Ice Age lacked the usual two or three premolars present in other bears; to compensate, the last molar is very elongated, with supplementary cusps. [21] The humerus of the cave bear was similar in size to that of the polar bear , as were the femora of females.
The last glacial period, commonly referred to as the "Ice Age", spanned 125,000 [40] –14,500 YBP [41] and was the most recent glacial period within the current ice age, which occurred during the last years of the Pleistocene era. [40]
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus).
