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.

Quaternary science is a field of study which involves geography, biology, chemistry, and physics. [4] Its focus is during the Quaternary Period – a time period that started around 2.58 million years ago and which continues to the present day. [1] Earth has been affected by the events that occurred during the Quaternary Period – a time of ...
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 .
The extinction's extreme bias towards larger animals further supports a relationship with human activity rather than climate change. [145] There is evidence that the average size of mammalian fauna declined over the course of the Quaternary, [146] a phenomenon that was likely linked to disproportionate hunting of large animals by humans.

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 Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene Epoch made up of two stages: the Aquitanian and Burdigalian stages. [2] [3] The sub-epoch lasted from 23.03 ± 0.05 Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change.
