 by John Kricher, Professor of biology at Wheaton College in Norton, Massachusetts Dinosaurs-the word means "fearfully great reptile"-have been a source of fascination ever since their discovery in England early in the nineteenth century. Aside from birds, all dinosaurs have been extinct for 65 million years, yet, before then, they dominated Earth's terrestrial habitats for about 160 million years, far longer than primates, or humans, have been around.

 "March Onto Land" 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. After gaining a toehold on dry land, terrestrial vertebrates grew in number and diversity to become the most important large-bodied organisms on the planet.
