Top 5 Predators of The Pleistocene - Dead & Alive
The Pleistocene often colloquially referred to as the Ice Age) is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. Before a change finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being at 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek "most" and kainós latinized as cænus, "new".
At the end of the preceding Pliocene, the previously isolated North a...

Pleistocene Megafauna of Eurasia
Megafauna are any animals with an adult body weight of over 44 kg (97 lbs). Pleistocene megafauna is the set of large animals that lived on Earth during the Pleistocene epoch.
During the Pleistocene, the world saw a dramatic number of extinctions of very large
terrestrial species during the Quaternary extinction event.
Along with other subcontinents Eurasia also suffered from loss of many large animals due to extinction. Europe was perhaps hit most as today the largest European land mammal is the European bison or wisent.
List of these giants vanished forever is very large but here is the mention of 15 such beasts which roamed in Eurasia until very recently and are well recorded from fossils and cave arts.

Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

Pleistocene Park
Pleistocene Park is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia.
It is a 16 km2 (established in 1996) scientific nature reserve consisting of willow brush, grasslands, swamps, forests and a multitude of lakes.
The average temperature in January is about –33 °C and in July +12 °C; annual precipitation is 200–250 mm.
The reserve is surrounded by a 600 km2 buffer zone that will be added to the park by the regional government once the animals have successfully established themselves.
Pleistocene Park is owned and administered by a non-profit corporation, the Pleistocene Park Association.
An attempt is being made to recreate the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial peri...

The name is a combination of Ancient Greek "most" and kainós latinized as cænus, "new".
At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two regions and changing ocean circulation patterns, with the onset of glaciation in the Northern Hemisphere occurring around 2.7 million years ago. During the Early Pleistocene (2.58-0.8 Ma), archaic humans of the genus Homo originated in Africa and spread throughout Afro-Eurasia. The end of the Early Pleistocene would be marked by the Mid-Pleistocene Transition, with the cyclicity of glacial cycles changing from 41,000 year cycles to 100,000 year cycles.

Pleistocene Park is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia.
It is a 16 km2 (established in 1996) scientific nature reserve consisting of willow brush, grasslands, swamps, forests and a multitude of lakes.
The average temperature in January is about –33 °C and in July +12 °C; annual precipitation is 200–250 mm.
The reserve is surrounded by a 600 km2 buffer zone that will be added to the park by the regional government once the animals have successfully established themselves.
Pleistocene Park is owned and administered by a non-profit corporation, the Pleistocene Park Association.
An attempt is being made to recreate the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period.
The primary aim of Pleistocene Park is to recreate the mammoth steppe (ancient taiga/tundra grasslands that were widespread in the region during the last ice age).
The key concept is that animals, rather than climate, maintained that ecosystem. Reintroducing large herbivores to Siberia would then initiate a positive feedback loop promoting the reestablishment of grassland ecosystems.
It will test the hypothesis that repopulating with large herbivores (and predators) can restore rich grasslands ecosystems, as expected if overhunting, and not climate change, was primarily responsible for the extinction of wildlife and the disappearance of the grasslands at the end of the Pleistocene epoch.
Here the hypothesis is that the change from tundra to grassland will result in a raised ratio of energy emission to energy absorption of the area, leading to less thawing of permafrost and thereby less emission of greenhouse gases.
To study this, large herbivores have been released, and their effect on the local fauna is being monitored.
Preliminary results point at the ecologically low-grade tundra biome being converted into a productive grassland biome, and at the energy emission of the area being raised.
This argument is the basis for rewilding Pleistocene Park's landscape with megafauna that were previously abundant in the area, as evidenced by the fossil record.
The grassland-steppe ecosystem that dominated Siberia during the Pleistocene disappeared 10,000 years ago and was replaced by a mossy and forested tundra and taiga ecosystem.
