The term “Carboniferous” (“coal bearing”) is descriptive, but Conybeare and Phillips expected that the Carboniferous System would be widely recognized by its distinctive fossils rather than its lithology (Eicher 1976). Significant Mississippian events. During the Mississippian Period, shallow seas covered much of North America.The most well known of all geological periods is the Jurassic period of the Mesozoic era (the movie Jurassic Park, of course, has something to do with that).

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. Devonian Period (417-354 mya) Intense reef building activity in shallow-water habitats indicates that the Devonian climate is, on the whole, warm and stable. Early relatives of squids called ...

The Devonian period is an interval of about 57 million years defined on the geologic time scale as spanning roughly from 416 to 359 million years ago (mya), and being noteworthy as a period of great diversification of life with the first appearance of amphibians, seed-bearing plants, sharks, lobe-finned fish, and ammonite mollusks.The Devonian period is the fourth of 6 periods making up the ...The Carboniferous Period (358- 299 Million years ago) was the time of large invertebrates, which were able to grow to those sizes thanks to the high level of... ….
