A mammoth is any species of the extinct elephantid genus Mammuthus. They lived from the late Miocene epoch into the Holocene until about 4,000 years ago, with mammoth species at various times inhabiting Africa, Asia, Europe, and North America. Mammoths are distinguished from living elephants by their spirally twisted tusks and in at least some later species, the development of numerous adaptions to living in cold environments, including a thick layer of fur.
A pika is a small, mountain-dwelling mammal native to Asia and North America. With short limbs, a very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. The large-eared pika of the Himalayas and nearby mountains lives at elevations of more than 6,000 m (20,000 ft).
Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka Peninsulas in Russia as well as Alaska in the United States and the Yukon in Canada.
The woolly rhinoceros is an extinct species of rhinoceros that inhabited northern Eurasia during the Pleistocene epoch. The woolly rhinoceros was a member of the Pleistocene megafauna. The woolly rhinoceros was covered with long, thick hair that allowed it to survive in the extremely cold, harsh mammoth steppe. It had a massive hump reaching from its shoulder and fed mainly on herbaceous plants that grew in the steppe. Mummified carcasses preserved in permafrost and many bone remains of woolly rhinoceroses have been found. Images of woolly rhinoceroses are found among cave paintings in Europe and Asia. The range of the woolly rhinoceros contracted towards Siberia beginning around 17,000 years ago, with the youngest known records being around 14,000 years old in northeast Siberia, coinciding with the Bølling–Allerød warming, which likely disrupted its habitat, with environmental DNA records possibly extending the range of the species around 9,800 years ago. Its closest living relative is the Sumatran rhinoceros.
The steppe bison or steppe wisent is an extinct species of bison. It was widely distributed across the mammoth steppe, ranging from Western Europe to eastern Beringia in North America during the Late Pleistocene. It is ancestral to all North American bison, including ultimately modern American bison. Three chronological subspecies, Bison priscus priscus, Bison priscus mediator, and Bison priscus gigas, have been suggested.
Panthera spelaea, commonly known as the cave lion, is an extinct Panthera species that was native to Eurasia and northwest North America during the Pleistocene epoch. Genetic analysis of ancient DNA has revealed that while closely related, it was a distinct species genetically isolated from the modern lion, with the genetic divergence between the two species estimated at around 500,000 years ago. The earliest fossils of the P. spelaea lineage in Eurasia date to around 700,000 years ago. It is closely related and probably ancestral to the American lion. The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna, and an important apex predator across its range. It became extinct about 13,000 years ago. It closely resembled living lions with a coat of yellowish-grey fur though unlike extant lions, males appear to have lacked manes.
The mammoth steppe, also known as steppe-tundra, was once the Earth's most extensive biome. During glacial periods in the later Pleistocene it stretched east-to-west, from the Iberian Peninsula in the west of Europe, across Eurasia to North America, through Beringia and northwest Canada; from north-to-south, the steppe reached from the Arctic southward to southern Europe, Central Asia and northern China. The mammoth steppe was cold and dry, and relatively featureless, though climate, topography, and geography varied considerably throughout. Certain areas of the biome—such as coastal areas—had wetter and milder climates than others. Some areas featured rivers which, through erosion, naturally created gorges, gulleys, or small glens. The continual glacial recession and advancement over millennia contributed more to the formation of larger valleys and different geographical features. Overall, however, the steppe is known to be flat and expansive grassland. The vegetation was dominated by palatable, high-productivity grasses, herbs and willow shrubs.
The Older Dryas was a stadial (cold) period between the Bølling and Allerød interstadials, about 14,000 years Before Present, towards the end of the Pleistocene. Its date range is not well defined, with estimates varying by 400 years, but its duration is agreed to have been around two centuries.
Yedoma is an organic-rich Pleistocene-age permafrost with ice content of 50–90% by volume. Yedoma are abundant in the cold regions of eastern Siberia, such as northern Yakutia, as well as in Alaska and the Yukon.
Bison occidentalis is an extinct species of bison that lived in North America, from about 11,700 to 5,000 years ago, spanning the end of the Pleistocene to the mid-Holocene.
Lyuba is a female woolly mammoth calf who died c. 42,000 years ago at the age of 30 to 35 days. She was formerly the best preserved mammoth mummy in the world, surpassing Dima, a male mammoth calf mummy which had previously been the best known specimen.
The Badyarikha is a river in Yakutia in Russia, a right tributary of the Indigirka. The length of the Badyarikha is 545 kilometres (339 mi) and the area of its drainage basin is 12,200 square kilometres (4,700 sq mi). Its sources are located on the northern slopes of the Moma Range
The woolly mammoth is an extinct species of mammoth that lived from the Middle Pleistocene until its extinction in the Holocene epoch. It was one of the last in a line of mammoth species, beginning with the African Mammuthus subplanifrons in the early Pliocene. The woolly mammoth began to diverge from the steppe mammoth about 800,000 years ago in Siberia. Its closest extant relative is the Asian elephant. The Columbian mammoth lived alongside the woolly mammoth in North America, and DNA studies show that the two hybridised with each other. Mammoth remains had long been known in Asia before they became known to Europeans. The origin of these remains was long a matter of debate and often explained as being remains of legendary creatures. The mammoth was identified as an extinct species of elephant by Georges Cuvier in 1796.
The Late Pleistocene to the beginning of the Holocene saw the extinction of the majority of the world's megafauna, which resulted in a collapse in faunal density and diversity across the globe. The extinctions during the Late Pleistocene are differentiated from previous extinctions by its extreme size bias towards large animals, and widespread absence of ecological succession to replace these extinct megafaunal species, and the regime shift of previously established faunal relationships and habitats as a consequence. The timing and severity of the extinctions varied by region and are thought to have been driven by varying combinations of human and climatic factors. Human impact on megafauna populations is thought to have been driven by hunting ("overkill"), as well as possibly environmental alteration. The relative importance of human vs climatic factors in the extinctions has been the subject of long-running controversy.
Yuka is the best-preserved woolly mammoth carcass ever found. It was discovered by local Siberian tusk hunters in August 2010. They turned it over to local scientists, who made an initial assessment of the carcass in 2012. It is displayed in Moscow.
The giant pika or Wharton's pika is an extinct mammal species in the family Ochotonidae. It lived during the Pleistocene and early Holocene in northern parts of North America. Very similar forms have also been found also in Siberia.
The Yana Rhinoceros Horn Site is an Upper Palaeolithic archaeological site located near the lower Yana River in northeastern Siberia, Russia, north of the Arctic Circle in the far west of Beringia. It was discovered in 2001, after thawing and erosion exposed animal bones and artifacts. The site features a well-preserved cultural layer due to the cold conditions, and includes hundreds of animal bones and ivory pieces as well as numerous artifacts, which are indicative of sustained settlement and a relatively high level of technological development. With an estimated age of around 32,000 calibrated years before present, the site provides the earliest archaeological evidence for human settlement in this region, or anywhere north of the Arctic Circle, where people survived extreme conditions and hunted a wide range of fauna before the onset of the Last Glacial Maximum. The Yana site is perhaps the earliest unambiguous evidence of mammoth hunting by humans.
Equus lenensis, the Lena horse, is an extinct species of horse from the Late Pleistocene and Holocene of Siberia. Some sources have considered it a subspecies of the wild horse.
