After Man: A Zoology of the Future is a 1981 speculative evolution book written by Scottish geologist Dougal Dixon and illustrated by several illustrators including Diz Wallis, John Butler, Brian McIntyre, Philip Hood, Roy Woodard and Gary Marsh. The book also features a foreword by Desmond Morris. "After Man" explores a hypothetical future set 50 million years from now, a time period Dixon dubs the "Posthomic", which is inhabited by animals that have evolved from survivors of a mass extinction succeeding our own time.
