In geologic time , the Silurian Period, the third period of the Paleozoic Era , covers the time from roughly 440 million years ago (mya) until 410 mya. The name, Silurian, derives from the Silures, an ancient British tribe. The Silurian Period spans two epochs. The Early Silurian Epoch is the most ancient, followed by the Late ...Continental Masses – 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. Its climate was marked by massive temperature fluctuations as continental masses shifted around the Earth’s surface.Cambrian explosion, the unparalleled emergence of organisms between 541 million and approximately 530 million years ago at the beginning of the Cambrian Period. The event was characterized by the appearance of many of the major phyla (between 20 and 35) that make up modern animal life. Many other.The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years. At the other end of the Paleozoic, the largest mass extinction in history wiped out approximately 90% of all marine animal species.Paleozoic Era: Devonian. Back.

As such, the Phanerozoic Eon includes the Paleozoic Era , the Mesozoic Era , and the current Cenozoic Era . The Phanerozoic Eon and constituent eras are then further divided into 12 geologic ...Over the Paleozoic and Mesozoic different corals have been important reef builders. There have been three major types of corals: rugose, tabulate, and scleractinian. Rugose and tabulate corals were important in the Paleozoic, but did not make it past the Permian extinction. Scleractinian corals were important after the Permian and into the present.Geologists have mapped out a time scale that is a “calendar” of Earth’s geologic history. The scale of geologic time starts some 4 billion years ago, when Earth’s crust was formed. Earth itself is slightly older than this, but when it was first formed the planet was in a hot and thick liquid form. As it cooled, the surface of the planet ...
