What is the first period of the paleozoic era
Fish evolved, and plants and animals started the move from the ocean onto dry land. Most plants and animals from this time are extinct in our modern world, which is why the Paleozoic is named for “ancient life." The 6 periods in this era are described below, as shown in the "Fossils Tell a Scientific Story" exhibit in the Hall of Evolution. In the subsequent Cambrian Explosion (a major event of great diversification at the beginning of the Paleozoic era, which commenced after the breakup of an earlier supercontinent called Panotia), they continued to evolve through the three major geologic eras of the Phanerozoic eon: the Paleozoic Era, which commenced 542 million years …
