End of paleozoic era.

The Paleozoic Era on the geological time scale is also known as the Primary Era or simply as the Paleozoic. It is the first era of the Phanerozoic Eon (which begins 541 million years ago and ends in our present days), which is followed by the Mesozoic and Cenozoic. It is also known as the “Age of Invertebrates”. Relatives of insects, crabs, and spiders, there were over 20,000 trilobite species that lived between the Cambrian and the end of the Paleozoic Era when they went extinct, some 252 million years ago. Prolific survivors with a segmented body plan that could be easily modified and altered, they soon dominated the seafloor. The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon, spanning from roughly 541 to 252.2 million years ago (ICS, 2004). It is the longest of the Phanerozoic eras, and is subdivided into six geologic periods (from oldest to least old): the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and ...The largest mass extinction happened at the end of the Paleozoic Era. The Permian-Triassic mass extinction event saw about 96% of marine life go extinct, along with 70% of terrestrial life. Even insects weren't immune to this mass extinction event like many of the others in history.

Mesozoic. Mesozoic (252-66 million years ago) means 'middle life' and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you. It ended with a massive meteorite impact that caused a mass extinction, wiping out the dinosaurs and up to 80% of life on Earth.The geologic era in which humans have evolved and spread over the Earth is the Cenozoic Era.

Major events in each period of the Paleozoic Era are described in Figure below. The era began with a spectacular burst of new life. This is called the Cambrian explosion.

That cataclysmic event, the largest mass die-off in planetary history, has become fittingly known as the Great Permian Extinction, and also happens to serve as the end line for the entire Paleozoic era. Trilobites evolved continually throughout their incredibly long march through “deep time” history. During that extended stay they inhabited ...

The Paleozoic Era ended with the largest extinction event of the Phanerozoic Eon, the Permian–Triassic extinction event.
