But it had its ups and downs.”. Some of the key highlights from the Paleozoic Era include: CAMBRIAN EXPLOSION: Bony fish diversified during the Cambrian explosion. Just to end in the largest extinction in Earth ... The drying out of the coal swamps during the Pennsylvanian and Early Permian diminished many of the environments of these Paleozoic amphibians, with the result that many types died out. They were supplanted by reptiles in the Triassic Period—the "Age of Reptiles". However, both large and small amphibians still continued to flourish in rivers ...

Eons may be further divided into smaller chunks called eras, and each era is divided into periods. Figure 12.1 shows you what the geologic time scale looks like. We now live in the Phanerozoic eon, the Cenozoic era, and the Quarternary period.The Paleozoic era (from the Greek palaio, meaning "old" and zoion, "animals," meaning "ancient life") is an interval of about 291 million years defined on the geologic timescale as spanning roughly from 542 to 251 million years ago (mya), and as being the earliest of three eras of the Phanerozoic eon.

Instead, they represent an abrupt mass extinction that was one of the largest to occur in the past half billion years. The final mass extinction of the era, which ...Remember the Paleozoic Era just before underwent a remarkable diversification in life (Cambrian explosion). It was only to end in the largest extinction event in Earth’s history (Permian-Triassic Extinction). But life didn’t completely vanquish at this point. When Earth’s climate became hotter and drier, rainforests began to collapse.
During the Paleozoic Era, there were multi-cellular organisms like trilobites, mollusks, jawless fish, seaweeds and finally, jawed fish, sharks, plants and early amphibians and reptiles.and then out-competed the amphibians. By the end of the Paleozoic Era, the decomposition of prolific plant life in oxygen-deficient environments led to the formation of widespread coal deposits.
