Roughly 600 Million years ago the first forms of complex life began swimming in the salty oceans of our planet. How life evolved from primitive, single-celled creatures into landlubbing, consciousness-seeking humans is the fascinating story of Planet Ocean. The stars of evolution - from fishy characters like pikaia and eustheopteron to land giants like tyrannosaurus and parasaurolophus - come to life in Ray Troll's "Out of the Ooze & Born to Cruise" art. And on this illustrated time-trip, writer Brad Matsen offers down-to-earth descriptions of today's scientific theories, together with firsthand accounts of sleuthing for ancient clues in some of North America's richest fossil beds.
