The paleozoic era would last how many days
The Paleozoic ("old life") era was the first and longest era of the Phanerozoic eon, lasting from 538.8 to 251.9 Ma. During the Paleozoic, many modern groups of life came into existence. Life colonized the land, first plants, then animals. Two major extinctions occurred. The geologic record of the continent of Europe is a classic example of how a continent has grown through time. The Precambrian rocks in Europe range in age from about 3.8 billion to 541 million years. They are succeeded by rocks of the Paleozoic Era, which continued to about 252 million years ago; of the Mesozoic Era, which lasted until about 66 million years ago; and of the Cenozoic Era (i.e ...
