The Quaternary period (from 2.588 ± 0.005 million years ago to the present) has seen the extinctions of numerous predominantly megafaunal species, which have resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe. The Late Quaternary glacial maximum in the Eurasian Arctic occurred around 90 ka BP, in strong contrast to the ice sheets over Scandinavia and North America, which at that time were much smaller than during the LGM. Mark Maslin & Jonathan Adams. This one started about 2.58 million years ago and is still going on, this time with significantly milder temperatures. During and between these glacial periods, rapid changes in climate and sea level have occurred, and environments worldwide have been altered.

The glacial landscapes were dominated by ice several kilometres thick that covered all but the highest peaks in the interior. Climate change and the developments it spurs carry the narrative of the Quaternary, the most recent 2.6 million years. Glaciation During the Quaternary The beginning of the Quaternary, the Early Pleistocene (2.6-0.8 Ma) was characterized by climatic fluctuations dominated by the 41 ka orbital precession cycle, during which relatively few cold periods were sufficiently cold and long to allow the development of substantial ice sheets. Quaternary Ice Age Each long interval of glaciation is typically marked by many glacial advances and retreats, which correlate roughly with fluctuations in climate between colder (glacial) and . The Quaternary glaciation started just a few million years ago - and is still going on. The quaternary period began 2.6 million years ago and extends into the present. The glacial history of the Tons River Valley reveals significant changes in the glacier extent during the late Quaternary driven by regional and global climatic changes.
