Section 3: The Paleozoic Era. • First four-legged animals developed began. The Paleozoic Era lasted from about 540 million years ago to about 248 million years ago. During this time period of about 292 million years, shallow seas came inland several times. Sharks and other fish, along with many other kinds of animals, lived in the water. In subsequent periods of the Paleozoic Era, invertebrates such as octopuses, shelled mollusks, corals and starfish evolved, along with the first fish, amphibians and reptiles.
