During the Carboniferous Period, Priapulids first entered the scene. These marine worms grew to a large size due to the higher concentrations of oxygen in the Earth’s atmosphere and because of the moist, swampy environment. These factors also allowed millipede-like creatures known as Arthropleura to get about 2.6 meters (7.8 feet) in length.All seven Devonian stages have been defined by Global Boundary Stratotype Sections and Points (GSSPs), but revisions of the base of the Emsian and of the Devonian–Carboniferous boundary are ongoing.Permian Period, in geologic time, the last period of the Paleozoic Era.The Permian Period began 298.9 million years ago and ended 252.2 million years ago, extending from the close of the Carboniferous Period to the outset of the Triassic Period..

Life in the Carboniferous seas was remarkably different from the preceding Devonian. This was due to the extinction event that occurred during the Late Devonian, which wiped out most of the marine invertebrates at the time.
The Age of Oxygen (400 million to 290 million years ago) As plants became firmly established on land, life once again had a major effect on Earth’s atmosphere during the Carboniferous Period.

The end of the Devonian period was marked by a mass extinction event. Carboniferous Period .

The Devonian Period ended with one of the five great mass extinctions of the Phanerozoic Era.
