The Late Devonian extinction consisted of several extinction events in the Late Devonian Epoch, which collectively represent one of the five largest mass extinction events in the history of life on Earth.The term primarily refers to a major extinction, the Kellwasser event, also known as the Frasnian-Famennian extinction, which occurred around 372 million …The Carboniferous was a time of diverse marine invertebrates. The Late Devonian Period experienced major extinctions within some marine invertebrate groups, and Carboniferous faunas reflect a different composition from what had prevailed earlier in the Paleozoic Era.The Carboniferous is a geologic period and system that extends from the end of the Devonian period, about 359.2 ± 2.5 Ma (million years ago), to the beginning of the Permian period, about 299.0 ± 0.8 Ma.

The Carboniferous period dates from 360 million to 280 million years ago. It gets its name from the vast deposits of coal produced when fluctuating seas drowned the tropical forests that covered much of North America and Europe. The later Paleozoic (286 million to 570 million years ago) was a world that would be recognizable to us. Paleozoic Era, or Palaeozoic Era, Major interval of geologic time, c. 542–251 million years ago.

The extinct Progymnospermophyta is thought to be ancestral to seed plants. The earliest recognized group of gymnospermous seed plants are of the extinct Pteridospermophyta (pteridosperms or seed ferns), which originated in the Devonian and were widespread by the Carboniferous.The shallow seas that covered Oklahoma during parts of the Silurian, Devonian and Carboniferous periods were home to generally similar communities.
