The Devonian Period, 410 to 360 million years ago, is best known as the "age of fishes". While it's true that fish experienced an explosive radiation at this time, it also marked a major change in the terrestrial ecosystem as life began to move wholesale from the water to the land. This period saw the widespread colonization of the land by vascular plants and the formation of the first forests, while beneath their spreading branches the newly evolved tetrapod animals took their first tentative steps out of the water.
