It is the longest of the Phanerozoic eras, lasting from 538.8 to 251.902 million years ago, and is subdivided into six geologic periods (from oldest to youngest): the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
What animals went extinct in the Paleozoic Era?
By the end of the Paleozoic, cycads, glossopterids, primitive conifers, and ferns were spreading across the landscape. The Permian extinction, 251.4 million years ago, devastated the marine biota: tabulate and rugose corals, blastoid echinoderms, graptolites, the trilobites, and most crinoids died out.
Did the Paleozoic Era have dinosaurs?
Much of the land was dominated by large reptiles, the early ancestors of the dinosaurs. However, the event that marked the end of the Paleozoic period was the massive extinction that wiped out nearly 96% of all marine life and 70% of land animals. Only a few species survived including some reptiles.
What time period was 200 million years ago?
The Jurassic period
The Jurassic period, from about 200 million to 145 million years ago, ushered in birds and mammals.
What are the 7 periods from oldest to youngest in the Paleozoic?
