The period of Earth's history that began 2.5 billion years ago and ended 542.0 million years ago is known as the Proterozoic, which is subdivided into three eras: the Paleoproterozoic (2.5 to 1.6 billion years ago), Mesoproterozoic (1.6 to 1 billion years ago), and Neoproterozoic (1 billion to 542.0 million years ago).*.1. Introduction. During the whole Phanerozoic, mass extinctions stressed the marine biota many times. They triggered disappearances of numerous species, genera, families, and even high-order groups of marine organisms, and they were often associated with outstanding environmental catastrophes such as global events of anoxia and euxinia, unusual warming and planetary-scale glaciations, massive ...One of the ways history is commonly divided is into three separate eras or periods: the Ancient Period (3600 BC – 500 AD), the Middle Ages (500 -1500), and the Modern Era (1500-present). According to this classification, the eras last hundreds of years, even thousands of years in the case of the Ancient Period.

The Permian Period, is the last period of the Paleozoic Era and famous for its ending epoch event, the largest mass extinction known to science.

Mesozoic Era (251-66 Ma) Triassic Period (251-202 Ma) Early in the Triassic Period, the shallow seas of the Paleozoic began to recede and southern Arizona entered a period of uplift, resulting in the formation of mountains.
