Compare the carboniferous period to the devonian period..
Atmospheric CO 2 concentrations in the latest Carboniferous period (∼ 300–310 Ma) have recently been empirically estimated to fluctuate wildly between ∼ 150 and 700 ppm in response to variations of Earth’s orbital parameters. For comparison, Quaternary CO 2 values vary over glacial cycles between ∼ 180 and 300 ppm .

In the case of plants, the adaptation was the further evolution of the seed, which first appeared in the Devonian Period. In the case of animals, it was the amniotic egg—a key feature in the origin of reptiles.There are many unanswered questions about the late Paleozoic. The Mississippian (early Carboniferous Period) began with a spike in atmospheric oxygen, while carbon dioxide plummeted to new lows. This destabilized the climate and led to one, and perhaps two, ice ages during the Carboniferous. Devonian. In the Devonian Period, Britain lay south of the equator and had a semi-arid climate.
