This is not to say that a particular park has only rocks from the specified period. Rather, rocks in selected parks exemplify a certain event or preserve fossils or rocks from a certain geologic age.The period, and the Paleozoic era, came to a calamitous close 251 million years ago, marking a biological dividing line that few animals crossed. The Permian extinction —the worst extinction event in the planet's history —is estimated to have wiped out more than 90 percent of all marine species and 70 percent of land animals.The Paleozoic Era (539–252 Ma) is in the Phanerozoic Eon, occurring after the Neoproterozoic Era, and before the Mesozoic Era. It is a time for great plant innovation and evolution. During this time land plants evolve and emerge from water, begin as lowly moss-sized plants, and become towering trees by the end of the Devonian Period.
