THE EVOLUTION OF TIME

Sigua, Joanna Marie T. 11- Mencius

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, where rocks from this age were first studied.

PRECAMBRIAN

4.8 BILLION YEARS AGO

The Paleozoic Era, which ran from about 542 million years ago to 251 million years ago, was a time of great change on Earth. The era began with the breakup of one supercontinent and the formation of another. Plants became widespread. And the first vertebrate animals colonized land.The Paleozoic Era, which ran from about 542 million years ago to 251 million years ago, was a time of great change on Earth.

The Mesozoic Era is the age of the dinosaurs and lasted almost 180 million years from approximately 250 to 65 million years ago. This era includes 3 well known periods called the Triassic, Jurassic, and Cretaceous periods. This allowed the dinosaurs to step in and settle into their role as the lords of the earth.The Mesozoic Era is the age of the dinosaurs and lasted almost 180 million years from approximately 250 to 65 million years ago.

MESOZOIC

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.Cenozoic Era, third of the major eras of Earth's history, beginning about 66 million years ago and extending to the present.
