Silesian (series)

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

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.

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

gollark: I suppose you could do one computer per, say, 32 modems.

gollark: Better than wasting server resources with an unreasonable amount of computers.

gollark: Just use full block modems to attach more modems to your computer; why use a bunch of computers for modem monitoring?

gollark: ¿¿¿

gollark: Just having an adapter block doesn't allow it to magically do anything. People need to explicitly program in mod integration.
