It was named for Silesia, a region that stretches over the Czech Republic, Poland and Germany.
Geology
It follows or lies on top of the Dinantian epoch/series and lasted from roughly 326.4 to 299.0 Ma ago.
The base of the Silesian is undefined, the top is defined by the first appearance of the conodont Streptognathodus isolatus.
Subdivisions
The Silesian is subdivided into three stages, from young (upper) to old (lower):
