This full-color volume depicts life's migration from the sea to the land and the rise of the first terrestrial organisms. Following the appearance of the first land plants and terrestrial invertebrates, some animals with backbones ventured out of the water--and grew in number and diversity to become the most important large-bodied organisms on the planet. By the Middle Triassic period, the evolutionary stage was set for the rise of many new and distinct species, including mammals and dinosaurs.
