Subdivisions of the Carboniferous system in Europe compared with the official ICS-stages.

The Silesian is in the geologic timescale of Europe a series or epoch, a subdivision of the Carboniferous system or period. It follows or lies on top of the Dinantian epoch/series and lasted from roughly 326.4 to 299.0 Ma ago.[citation needed] The Silesian is subdivided into three stages: (from young to old) Stephanian, Westphalian and Namurian. It was named for Silesia, a region that stretches over the Czech Republic, Poland and Germany.

The base of the Silesian is undefined, the top is defined by the first appearance of the conodont Streptognathodus isolatus.
