The Silesian is a subdivision (a series or epoch) of the Carboniferous system or period in the geologic timescale of western and central Europe.[1] It was named for Silesia, a region that stretches over the Czech Republic, Poland and Germany.
Geology
The Silesian follows or lies on top of the Dinantian epoch/series and lasted from roughly 330 to 299 Ma ago.[1]
The base of the Silesian was defined in 1958 as the first occurrence of the ammonoid Cravenoceras leion,[1] 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):[2]
