Weegy: The name "Carboniferous" reflects the most famous attribute of this geologic period: the massive swamps that cooked, over tens of millions of years, into today's vast reserves of coal. [ However, the Carboniferous period was also notable for the appearance of new terrestrial vertebrates, including the very first amphibians and lizards. The Carboniferous was the second-to-last period of the Paleozoic Era (542-250 million years ago), preceded by the Cambrian, Ordovician, Silurian and Devonian periods and succeeded by the Permian period. The global climate of the Carboniferous period was intimately linked with its geography. During the course of the preceding Devonian period, the northern supercontinent of Euramerica merged with the southern supercontinent of Gondwana, producing the enormous Pangea, which occupied much of the southern hemisphere during the Carboniferous. This had a pronounced effect on air and water circulation patterns, with the result that a large portion of southern Pangea wound up covered by glaciers, and there was a general global cooling trend (which, however, didn't have much effect on the coal swamps that covered Pangea's more temperate regions). Oxygen made up a much higher percentage of the earth's atmosphere than it does today, fueling the growth of terrestrial megafauna, including dog-sized insects. ] (More)
