Subdivisions of the Carboniferous system in Europe compared with the official ICS-stages (as of 2018)

The Silesian is in the geologic timescale of Europe a series or epoch, a subdivision of the Carboniferous system or period.

It was named for Silesia, a region that stretches over the Czech Republic, Poland and Germany.

Geology

[edit]

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

Subdivisions

[edit]

The Silesian is subdivided into three stages, from young (upper) to old (lower):
