Paleozoic timeline
Abstract Updating magmatic profile in crucial constituent terranes across the Central Asian Orogenic Belt presents a key to chronicling the timeline of prolonged accretionary processes and termination of the Paleo-Asian Ocean in the northern China-southern Mongolia tract. Here we performed a systematic geochronological and geochemical study on a spectrum of Paleozoic intrusions from the ...Paleozoic Era. From an explosion of early life to the greatest extinction in history, the Paleozoic was a time of change. During this earliest era, living ...The Paleozoic is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous(in the U.S., this is divided into the Mississippian and Pennsylvanian Periods), and Permian. Most of these names derive from locations where rocks of these ages were first studied.

This is the largest of all known mass extinctions with a massive 96% of all species on Earth completely lost. It is no wonder, therefore, that this major mass extinction has been dubbed “The Great Dying.”Cenozoic Extinction of Dinosaurs First Dinosaurs Age of Amphibians Age of Invertebrates Permanian Triassic This whole section is referred to as: Precambrian Time Cambrian Paleozoic Mesozoic Cretaceous Tertiary Name: Period: Date: Geologic Timeline Analysis Directions: Begin by filling in the blank boxes on the time scale diagram on the right, using the diagram on p. 138.The Geologic Time Scale. The geologic time scale. Image by Jonathan R. Hendricks for the Earth@Home project. Note that the geologic time scale above is not scaled to time and mostly represents the Phanerozoic Eon. Mosts of geologic history (88%) happened during the Precambrian, which is represented by Hadean, Archean, and Proterozoic eons.
The Precambrian (/ p r i ˈ k æ m b r i. ə n,-ˈ k eɪ m-/ pree-KAM-bree-ən, -KAYM-; or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales ...Cenozoic Era, third of the major eras of Earth’s history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth’s flora and fauna evolved toward those of the present.Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and... Tertiary Period. Tertiary Period, former official interval of geologic time lasting from approximately 66 million to 2.6 million years ago.The Paleozoic era, from 541 to 252 million years ago, saw the rise of the first fish and the first land plants. It was also a time of great diversification, as new groups of animals evolved and formed complex ecosystems. The Mesozoic era, from 252 to 66 million years ago, is best known for the dinosaurs. This era also saw the evolution of birds and …Consequently, the Paleozoic Era ended with the largest extinction in Earth’s history. Invertebrates, fish, and amphibians evolved in the Paleozoic Eon. But reptiles and dinosaurs become the dominant life in the Mesozoic Era. Make sure you read more of our timelines to explore the history of Earth: Proterozoic Eon (2500 to 541 million years ago)

From the Greek words for “old’ and “life” (παλαιό and ζωή respectively), the Paleozoic Era denotes the earliest of three distinctive geologic eras of the Phanerozoic Eon.
