What are the four major eras of earths history?
1. Precambrian Era (earliest forms of life, such as bacteria and blue-green algae; later in the period, invertebrates such as jellyfish).2. Paleozoic Era (Pangaea; invertebrate life, such as trilobites, later in the era, followed by development of vertebrates, including fish; development of vertebrates, amphibians, and the beginnings of reptiles; development of simple plants, such as mosses and ferns)3. Mesozoic Era (Pangaea separates into continents; "Age of Reptiles"; dinosaurs, flowering plants, small mammals and birds)4. Cenozoic (Present Era) Ice Age; mammoths; gradual development of mammals, birds and other animals recognizable today; humans; flowering plants, forests, grasslands.)Edit:Actually the above answer can be disputed. The Precambrian is not considered an era, it is considered a supereon that is divided into three eons. Two of these eons are subdivided into a total of seven eras. Combine that with the three eras of the Phanerozoic Eon, and you have ten.So this question doesn't really make sense, considering there are actually ten eras.
