The Quaternary (/ k w ə ˈ t ɜːr n ə r i, ˈ k w ɒ t ər n ɛr i / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon.

Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
The extinction's extreme bias towards larger animals further supports a relationship with human activity rather than climate change. [150] There is evidence that the average size of mammalian fauna declined over the course of the Quaternary, [151] a phenomenon that was likely linked to disproportionate hunting of large animals by humans.

The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene. Megafauna of Pleistocene Europe (mammoths, cave lions, woolly rhino, reindeer, horses)
Prehistoric animals of the Pleistocene epoch, existing between 2.58 million and 11.7 thousand years ago, during the early Quaternary Period of the Cenozoic Era See also the preceding Category:Pliocene animals
The Quaternary Period, the Cenozoic Era geologic time unit from the end of the Pliocene Epoch, roughly 1.8−1.6 million years ago, to the present day. The Quaternary has 2 geologic/geochronologic subdivisions, the Pleistocene and the Holocene Epochs .
