The Westphalian is a regional stage or age in the regional stratigraphy of northwest Europe, with an age between roughly 315 [1] [2] and 307 [1] [3] Ma (million years ago).It is a subdivision of the Carboniferous System or Period and the regional Silesian Series.
Permo-Carboniferous time, about 300 million years ago, was a period of significant glaciation. The widespread distribution of Permo-Carboniferous glacial sediments in South America, Africa, Madagascar, Arabia, India, Antarctica and Australia was one of the major pieces of evidence for the theory of continental drift , and led ultimately to the ...
The categorisation of the past into discrete, quantified named blocks of time is called periodization. [1] This is a list of such named time periods as defined in various fields of study.
