Шаблон:Use dmy dates Шаблон:Infobox rockunit The Fish Bed Formation is a geologic formation in Scotland, United Kingdom. The fluvial to lacustrine sandstones, shales, siltstones and conglomerates preserve flora, arthropods, among which eurypterids, invertebrates and early fish fossils dating back to the Wenlock epoch of the Silurian period.[1]

Description

Paleogeography of the Early Silurian, 435 Ma

The fish beds are contained within red-bed sequences comprising conglomerates, sandstones and siltstones that exhibit sedimentological features suggestive of deposition in terrestrial–fluviatile and lacustrine environments (Bluck 2002). The sporomorph assemblage from the Fish Bed Formation indicates that it is entirely non-marine and was most likely deposited in a relatively permanent lacustrine setting (Wellman and Richardson 1993).[2]

The formation, at the time part of Avalonia, was deposited during the Grampian orogeny.
