An entertaining reconstruction of animal life in Southern California 4000 years ago during the Pleistocase era. Using information compiled through research and excavation by many scientists at La Brea's tar pits, the author has created a busy, violent world of fighting, eating, hunting animals. In the midst of his contemporaries, many of whom will be extinct while he lives, Racky the racoon escapes his enemies, finds a mate and watches animals not so wise as they perish in the tar pits. He sees fights among saber -- tooth cats and lions, wolves, coyotes, eagles, cloths, bears and the great monster, the Emperor Mammoth. Footnotes give the scientific name for each animal, but unfortunately, the descriptions of the animals are not graphic enough to delineate any deviations from the present forms of wolves, coyotes, camels, etc.
