Panthera spelaea, also known as the Eurasian cave lion, European cave lion or steppe lion, is an extinct Panthera species that most likely evolved in Europe after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion (Panthera leo) occurring in Africa and Asia.
Analysis of morphological differences and mitochondrial data support the taxonomic recognition of Panthera spelaea as a distinct species that genetically diverged from the lion about . Nuclear genomic evidence shows a more recent split approximately 500,000 years ago, with no subsequent interbreeding with the ancestors of the modern lion. It became extinct about 13,000 years ago.
Felis spelaea was the scientific name used by Georg August Goldfuss in 1810 for a fossil lion skull that was excavated in a cave in southern Germany. It possibly dates to the Würm glaciation.
Several authors regarded Panthera spelaea as a subspecies of the modern lion, and therefore as Panthera leo spelaea.
One author considered the cave lion to be more closely related to the tiger based on a comparison of skull shapes, and proposed the scientific name Panthera tigris spelaea.
Results from morphological studies showed that it is distinct in cranial and dental anatomy to justify the specific status of Panthera spelaea. Results of phylogenetic studies also support this assessment.
In 2001, the subspecies Panthera spelaea vereshchagini was proposed for seven specimens found in Siberia and Yukon, which have smaller skulls and teeth than the average P. spelaea. Before 2020, genetic analysis using ancient DNA provided no evidence for their distinct subspecific status; DNA signatures from P. spelaea from Europe and Alaska were indistinguishable, suggesting one large panmictic population. However, analysis of mitochondrial genome sequences from 31 cave lions showed that they fall into two monophyletic clades.

The woolly mammoth (Mammuthus primigenius) is an extinct species of mammoth that lived during the 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 East Asia. Its closest extant relative is the Asian elephant. The Columbian mammoth (Mammuthus columbi) lived alongside the woolly mammoth in North America, and DNA studies show that the two hybridised with each other.
Pleistocene Park (Pleystotsenovyy park) is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to re-create the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period. The project is being led by Russian scientists Sergey Zimov and Nikita Zimov, testing 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.
The woolly rhinoceros (Coelodonta antiquitatis) is an extinct species of rhinoceros that was native to 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.
A classical method for understanding the coupling between northern and southern hemispheres during millennial-scale climate events is based on the correlation between Greenland and Antarctic ice core records of atmospheric composition. Here we present a ne ...

During the last glacial cycle, Greenland temperature showed many rapid temperature variations, the so-called Dansgaard-Oeschger (DO) events. The past atmospheric methane concentration closely followed these temperature variations, which implies that the wa ...
