The Scremerston Formation is a geologic formation in England. It preserves fossils dating back to the Carboniferous period.{{Cite web|title=Fossilworks: Gateway to the Paleobiology Database|url=https://www.fossilworks.org|access-date=17 December 2021|website=fossilworks.org}}
It consists of layers of sandstone, siltstone, mudstone and coal, with occasional thin dolomite or limestone beds. Sandstones make up about 50% of the formation and are white, grey, brown or reddish brown, forming beds that are typically less than 15 m thick, but are known to reach 60m thick in places. The siltstones and mudstone layers are grey or brownish grey and non-calcareous. About 5% of the formation is made up of coal seams, which reach up to 1.5 m thick.{{cite web |url=https://webapps.bgs.ac.uk/lexicon/lexicon.cfm?pub=SCF |title=Scremerston Formation |author= |date= |website=British Geological Survey |publisher=British Geological Survey |access-date=14 April 2021 |quote=}} The Scremerston Formation was formed by the actions of a large river delta as well as marine deposits.{{cite web |url=http://nora.nerc.ac.uk/id/eprint/512724/1/CR07101N.pdf |title=The Scremerston Formation: results of a sedimentological study of onshore outcrop sections and offshore Well 42/13-2 |last=Jones |first=NS |date=2007 |website=Natural Environment Research Council |publisher=British Geological Survey |access-date=4 May 2021}} Evidence of the sedimentary layering is very evident along the cliffs at Cocklawburn beach near Scremerston, with plentiful marine fossils and pavement-like rock formations with wave-ripple cross-lamination.
