(1) The youngest geologic period; includes the present time (2) The latest period of time in the stratigraphic column, 0 - 2 million years, represented by local accumulations of glacial (Pleistocene) and post-glacial (Holocene) deposits which continue, without change of fauna, from the top of the Pliocene (Tertiary) The quaternary appears to be an artificial division of time to separate pre-human from post-human sedimentation As thus defined, the quaternary is increasing in duration as man's ancestry becomes longer

Quaternary Period
8 million years ago to the present. The Quaternary follows the Tertiary Period and is the more recent of the two periods of the Cenozoic Era. The Quaternary is subdivided into the Pleistocene Epoch and the Holocene Epoch and is characterized by major cyclical changes of climate on a global scale. These led to repeated invasions of vast areas by ice sheets. Its major biologic feature is the evolution and dispersion of humans. The dramatic changes of climate and environment in the Quaternary led to high rates of evolution and extinction, particularly among the mammals. The extinction of many large mammals toward the end of the last ice age may also be related to the rapid territorial expansion of humans
