The Ravenscar Group is a Jurassic lithostratigraphic group (a sequence of rock strata) which occurs within the Cleveland Basin of North Yorkshire and extends to both the Hambleton and Howardian Hills. The name is derived from Ravenscar on the North Yorkshire coast where rocks of this age occur. It was earlier known as the 'Middle Jurassic Series'.〔http://www.bgs.ac.uk/Lexicon/lexicon.cfm?pub=RAG〕〔British Geological Survey 1;50,000 scale geological map sheet (England and Wales series) no 34 ''Guisborough''〕 ==References==
