During the Paleozoic Era, which lasted 289 million years, plants and reptiles began moving from the sea to the land. The era has been divided into six periods: Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Several times during this era, seas appeared and disappeared in Kansas.During the Paleozoic Era, which lasted 289 million years, plants and reptiles began moving from the sea to the land. The era has been divided into six periods: Permian, Carboniferous, Devonian, Silurian, Ordovician, and Cambrian. Several times during this era, seas appeared and disappeared in Kansas.The Paleozoic Era, named after the Greek word for “ancient life” (Sedgwick, 1838), is the earliest and longest-lasting era of the Phanerozoic Eon.It began with the Cambrian explosion at ∼538.8 Ma, a major diversification of marine animals, and ended at 251.9 Ma with the end-Permian extinction, the greatest mass extinction in Earth's history (Fig. 1).

The Palaeozoic (or Paleozoic) era is the earliest of the three eras of the Phanerozoic. Its name means early life. It lasted from about 541 to 252 million years ago (mya), and ended with the greatest extinction event, the Permian-Triassic extinction event. Beginning. The Palaeozoic began with an explosion of life forms. ...Paleozoic definition, noting or pertaining to an era occurring between 570 million and 230 million years ago, characterized by the advent of fish, insects, ...Based on these maps, the proto-type basin and tectono-paleogeographic features of the Tarim basin during the Late Paleozoic are illustrated. The Devonian to Permian is an important period of terranes/island-arcs accretion and oceanic closure along the periphery of the Tarim block, and a critical period when the polarity of Tarim basin (orientation of …Paleozoic Era. During the Paleozoic Era (541 to 252 million years ago) Fish diversified and marine organisms were very abundant during the Paleozoic. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.This indicates that the last eurypterids died either in the catastrophic extinction event at its end or at some point shortly before it. This extinction event, the Permian–Triassic extinction event, is the most devastating mass extinction recorded, and rendered many other successful Paleozoic groups, such as the trilobites, extinct.

The North Qinling orogen, central China, formed above an ancient ocean-continent subduction zone and contains widespread early-Paleozoic I-type granites. Previous studies have shown that the mantle wedge beneath the north Qinling unit was significantly metasomatized and isotopically enriched relative to the lower crust in the …Paleozoic paleotemperatures based on carbonates and phosphates (Figs. 3, 4) show similar trends such as very high late Cambrian and Early to Middle Ordovician temperatures (> 40 °C), high early ... ….

It was ...The Paleozoic era began around 542 million years ago with a massive explosion of life forms. It ended 291 million years later with the extinction of between 90 and 95 percent of life on the planet.

The Carboniferous Period is famous for its vast swamp forests, such as the one depicted here. Such swamps produced the coal from which the term Carboniferous, or "carbon-bearing," is derived. The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era. The term "Carboniferous" comes from England, in ... The Ordovician* lasted about 45 million years and saw the transition from very primitive to relatively modern life-forms in the seas. The “Ordovician radiation” which followed the late Cambrian extinctions, lead to a tripling of marine diversity, the greatest increase in the history of life, and giving the highest levels of diversity seen during the Paleozoic Era.Following the Cambrian Period, the biosphere continued to expand relatively rapidly. In the Ordovician Period (485.4 million to 443.4 million years ago), the classic Paleozoic marine faunas—which included bryozoans, brachiopods, corals, nautiloids, and crinoids—developed. Many marine species died off near the end of the Ordovician because ...
