HYPEROXYGENATED PERIOD. “Because metabolic oxygen demand increases with increasing body size, environmental oxygen concentration (pO2) is frequently invoked as an important constraint on the size of animals. Giant late Paleozoic insects, with wingspans as large as 70 cm, are the iconic example of the oxygen-body size link; hyperoxic conditions during the Carboniferous and Permian are thought to have permitted the spectacular sizes of the largest insects ever.”
