Absolute dating of the pennsylvanian period Chatswingers

In terms of absolute time, the Carboniferous Period began approximately 358.9 million years ago and ended 298.9 million years ago.

The term "Carboniferous" comes from England, in reference to the rich deposits of coal that occur there.From the beginning of this course, we have stated that the Earth is about 4.6 billion years old.How do we know this and how do we know the ages of other events in Earth history?These extinctions were followed by periods of species diversification, as the descendants of surviving organisms filled in abandoned habitats.from Torquay in Devon seemed intermediate in type between those of the Silurian System below and those of the Lower Carboniferous System above.In Europe, the Carboniferous Period is subdivided into the Dinantian and succeeding Silesian subsystems, but the boundary between those divisions is below the internationally accepted Mississippian-Pennsylvanian boundary.and northern Europe remained equatorial, while the China and Siberia cratons continued to reside at high latitudes in the Northern Hemisphere.This led to the conclusion that the fossil corals were marine equivalents of the terrestrial Old Red Sandstone rocks already known in .The recognition that such major paleogeographic differences existed was a great scientific advance, and it was soon confirmed when Sedgwick and Murchison visited Germany and again when Murchison discovered an intercalation of Devonian marine fossils and Old Red Sandstone fishes near , paleoclimate, paleobiogeography, and tectonic events.These stages are (from early to late) Tournaisian, Visean, and Serpukhovian for the Mississippian — and Bashkirian, Moscovian, Kasimovian, and Gzhelian for the Pennsylvanian.In addition to having the ideal conditions for the formation of coal, several major biological, geological, and climatic events occurred during this time.
