The geologic epoch of 1.8 million - 8,000 years ago– the earliest epoch of the Quaternary, also known as the "Great Ice Age."
Beginning two million years ago, this epoch saw the most recent ice ages and the coming of man to North America.
The first epoch of the Quaternary Period, beginning 2 to 3 million years ago and ending approximately 10,000 years ago. See also Holocene Epoch.
from two million to 11 thousand years ago; extensive glaciation of the northern hemisphere; the time of human evolution
the geological epoch within the Quaternary period, dating from approximately 1,000,000 - 10,000 years ago, during which much of the northern hemisphere was covered by glaciers. Paleo-Indians entered the Americas from Asia at the end of this era.
The period of time between 1.8 million and 10,000 years ago. On Earth this corresponds to the interval during which large continental glaciers repeatedly advanced and retreated across landmasses at high latitudes. Informally, this epoch is also called the "ice age".
geological time period extending from 2 million years to 10,000 years before present
The earliest Epoch of the Quaternary Period, beginning about 1.6 million years ago and ending 10,000 years ago. Commonly known as the ' Ice Age', a time with episodes of widespread continental glaciation. more details...
The interval from 1.5 million years ago till 10,000 years ago. During this time there were several advances and retreats of ice sheets in North America and Europe. In western North America there were a number of very large lakes such as Lake Bonneville.
a geologic time period, lasting from 1.8 million to 11,000 years ago, in which the most recent global cooling, or the ice ages, took place
An interval of the Quaternary period, from 1.8 million years before present to 10 thousand years before present.
subdivision of the Quaternary Period. Characterized by almost modern fossils (70% fossil mollusks still living organisms), major glaciations of the mid-latitudes, and with associated climatic and environmental changes. Ended roughly 10,000 years BP with the end of the last major glaciation.
the earlier of the two epochs comprising the Quaternary period.
The period of geologic time between 10,000 and 2.5 million years before the present. The Pleistocene essentially spans the same period of time known as the Ice Age.
The most recent period of extensive continental glaciation that saw large portions of North America and Eurasia covered with ice. It began about 2,000,000ybp (years before present) and ended about 10,000ybp.
( Ice Age) Period of time from about 2 million years ago to 10,000 years ago. During this period areas of land at higher and middle latitudes where covered with glacial ice.
The period from 2 500 000 to 10 000 years ago, during which continental glaciers periodically expanded to cover subpolar regions in both hemispheres.
