The Permian Period. The Permian Period is best known for the dramatic event which ended not only the period, but also the entire Paleozoic Era - an extinction of 95% of the then-living world. If we look ...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 reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America. The Permian period lasted from 299 to 251 million years ago* and was the last period of the Paleozoic Era. The distinction between the Paleozoic and the Mesozoic is made at the end of the Permian in recognition of the largest mass extinction recorded in the history of life on Earth. It affected many groups of organisms in many different ...

The Precambrian spans about 88 percent of Earth's history, beginning with the formation of Earth about 4.5 billion years ago and ending approximately 540 million years ago with the diversification of life, which marks the start of the Paleozoic era.

Introduction. The Paleozoic Era was a major interval of geologic time. It began 541 million years ago with a rapid expansion of life-forms and ended 252 million years ago with the largest mass extinction in Earth’s history.

It began 485.4 million years ago and ended 443.8 million years ago. The interval was a time of intense diversification (an increase in the number of species) of marine animal life in what became known as the Ordovician radiation. Pangea; the giant, single continent that existed at the end of the Paleozoic era; it eventually separated into present-day continents- as Pangea formed, coal swamps dried up and Earth's climate got cooler and dryer.
