The geological period of time (epoch) from about two million years ago to about 11,000 years ago, usually thought of as the Ice Age due to the multiple expansion and retreat of glaciers.

The earlier epoch of the Quaternary period or the corresponding system of rocks; 1.6 million-10,000 years ago; the "Ice Age."

The epoch of geologic time, informally called the 'The Great Ice Age' or the 'Glacial Epoch', that began ~1.8 million years ago and ended ~8,000 years ago (see the CVO's Geologic Time Scale). During this interval continental glaciers repeatedly formed and covered significant parts of the Earth's surface. Together, the Holocene and Pleistocene epochs comprise the Quaternary Period.

Division of Quaternary period, also known as Ice Age.

The geological period corresponding with the last or Great Ice Age. The onset of the Pleistocene is marked by an increasingly cold climate, by the appearance of Calambrian mollusca and Villafranchian fauna with elephant, ox, and horse species, and by changes in foraminifera. The oldest form of man had evolved by the Early Pleistocene, and in archaeological terms the cultures classed as Paleolithic all fall within this period. The date for the start of the Pleistocene is not well established, and estimates vary from 3.5 to 1.3 million years ago. The period ends with the final but gradual retreat of the ice sheets, which reached their present conditions around 10,300 BP.

A epoch in Earth history from about 2-5 million years to 10,000 years ago. A series of glacial and interglacial periods built the landforms and current biota of the Pacific Northwest during these times.

the first epoch of the Quaternary era, lasting about 990 thousand years and characterized by extensive glaciation of the northern hemisphere and the evolutionary development of Man; from Greek pleistos 'most' + kainos 'recent'.

Of or pertaining to the most recent period in the earth's history, roughly the past one million years. The period includes at least four major retreats and advances of continental glaciers.

The period of time ranging from 1.8 million to 11,000 years ago. This is the time period paleoecologists are getting a better understanding about from examining the contents of preserved packrat middens.

The last 1.6–2 million years (often synonymous with the ice ages) excluding the Holocene (from 10 000BP onwards). The Pleistocene is characterised by an alternating series of cold periods (glaciations) and warm periods (interglacials)

An epoch of the Quaternary period, spanning the time between 1.8 million years ago and the beginning of the Holocene at 8,000 years ago. It is named after the Greek words "pleistos" (most) and "ceno" (new).

It began one to two million years ago and lasted until the start of the Holocene, some 10,000 years ago. When the Quaternary is designated as an era, the Pleistocene is considered to be a period.

(pronounced PLEES-toh-seen) The Pleistocene was an epoch in geologic time that lasted from 1.8 million years ago until about 10,000 years ago (it was at the beginning of the Quaternary period). During this epoch, the first humans (Homo sapiens) evolved. Mammoths, mastodons, saber-toothed cats, giant ground sloths, and other Pleistocene megafauna (huge animals) lived. A mass extinction of large mammals and many birds happened about 10,000 years ago (at the end of this epoch), probably caused by climate changes (the last Ice Age ended).

part of the geologic timescale, corresponding to the time period from 1.81 million to 11,550 years before the present.

The Pleistocene epoch on the geologic timescale is the period from 1,808,000 to 11,550 years BP (Before Present). The name pleistocene is derived from the Greek (pleistos "most") and (kainos "new"). The Pleistocene follows the Pliocene epoch and is followed by the Holocene epoch.
