The geologic history of the northeastern United States is a story of active mountain building and the quieter processes of weathering, erosion, and deposition of sediments.The Northeast is at the edge of a continent (North America), but in the middle of a plate (the North American plate), which extends from the mid-Atlantic ridge to the West Coast.The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or paleontological events.

Permian Period, Paleozoic Era, Phanerozoic Eon [299 Myr - 252 Myr ] The Permian Period is named after the Perm region of Russia, where the types of fossils characteristic of that period were first discovered by geologist Roderick Murchison in 1841. The Permian, Pennsylvanian and Mississippian Periods are collectively referred to as the "age of …

The Permian is the last Period of the Paleozoic Era. It ended with the greatest mass extinction known in the last 600 million years. Up to 90% of marine species disappeared from the fossil record, with many families, orders, and even classes becoming extinct. On land insects endured the greatest mass extinction of their history.The Paleozoic Era begins after the Pre-Cambrian about 297 million years ago and ends with the start of the Mesozoic period about 250 million years ago. Each major era on the Geologic Time Scale has been further broken down into periods that are defined by the type of life that evolved during that span of time.After the Precambrian come the Paleozoic Era and Mesozoic Era. Last but not least is the Cenozoic (Sen-oh-ZOE-ik) Era, the one in which we live. The Cenozoic started about 65 million years ago. Each of these Eras, in turn, are divided into increasingly smaller divisions known as Periods, Epochs and Ages. ... That’s because Earth’s …The geologic timeline (also called the geologic time scale) is a system of measurement commonly used by earth scientists.

Introduction to the Mesozoic Era. 248 to 65 Million Years Ago. The Mesozoic is divided into three time periods: the Triassic (245-208 Million Years Ago), the Jurassic (208-146 Million Years Ago), and the Cretaceous (146-65 Million Years Ago).. Mesozoic means "middle animals", and is the time during which the world fauna changed drastically from that which had been seen in the Paleozoic.

Triassic Period. Jurassic* ammonites and dinosaurs made a huge comeback after their near extinction at the end of the Triassic. Oysters, crabs, lobsters, and teleost (modern) fish appear. Plesiosaurs and marine crocodiles first appeared, joining icthyosaurs, sharks, bony fish, cephalopods and many other marine predators.About the geologic time scale. Origins of a geologic time scale.

This is when life first appears on your timeline. During the Cambrian Period, at the beginning of the Paleozoic Era, there was a sudden explosion of life as new species started appearing rapidly. At this time, life was still restricted to the oceans.4. Discussion. The development of a well-corroborated timeline for terrestrialization is essential to our understanding of biogeochemical cycles. Vegetation is known to enhance the weathering of surface rocks and the sequestration of carbon, both of which have notable consequences for the long-term carbon cycle [ 7, 8 ].MIT geologists have now reconstructed a timeline of the Earth’s temperature during the early Paleozoic era, between 510 and 440 million years ago — a pivotal period when animals became abundant in a previously microbe-dominated world.

As noted earlier, the pattern of redox change in Neoproterozoic to Early Paleozoic oceans is debated, with estimates for when PO 2 reached 50% PAL ranging from 800 Ma to the Cambrian Period or later . However, in general, full oxygenation of ocean basins appears to have been achieved more than transiently only in the Paleozoic Era (48, 49 ...Precambrian, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago.
