|Devonian (dĭ-vō'nē-ən) Pronunciation Key
The fourth period of the Paleozoic Era, from about 408 to 360 million years ago. During this time there were three major landmasses: most of modern day North America and Europe were located along the equator; a portion of Siberia was located to the north; and a continent consisting of South America, Australia, Africa, India, and Antarctica was located in the Southern Hemisphere. In the early Devonian small plants dominated the landscape, but by the end of the Devonian ferns and seed plants had appeared, as had the first forests. The first tetrapods (terrestrial vertebrates) and terrestrial arthropods appeared, as did many new types of fish. See Chart at geologic time.
