The Devonian seas were dominated by brachiopods, such as the spiriferids. Red algae helped build the reef building. In the Lower Devonian ammonoids appeared and leaving us large limestone deposits form their shells. The Devonian is notable for the rapid diversification in fish.

Plants started to begin spreading beyond the wetlands during the Devonian. Toward the end of the Devonian first forests arose as steamed plants became strong. Some Devonian trees are known to grow up to 100 feet tall.
