{i} group of four; number four; second part of the Cenozoic era, present geologic period (Geology)
(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
(4) Geology Of, belonging to, or designating the geologic time, system of rocks, and sedimentary deposits of the second period of the Cenozoic Era, from the end of the Tertiary Period through the present, characterized by the appearance and development of human beings and including the Pleistocene Epoch and the Holocene Epoch [Back To Top]
