This book details the long, diverse, and complex phylogenetic history of elephants and their fossil relatives (the Proboscidea), whose origin is deeply embedded some 60 million years ago in Africa. Most of the major evolutionary events of proboscideans occurred in Africa, and these are examined in their geological, paleoecological, geographic, and faunal contexts. Updated information about feeding adaptations, taxonomy and systematics, genetics, and site occurrences is included and summarized in tables, figures, and charts.
