Headington stone is a limestone from the Headington Quarry area of Oxford, England.〔Clive Aslet, (The stone that built a country ), ''The Daily Telegraph'', 20 March 2007.〕〔Mary D. Lobel (editor), (Parishes: Headington ), ''A History of the County of Oxford: Volume 5: Bullingdon hundred'',1957, pp. 157–168.〕〔W.J. Arkell, ''(Oxford Stone )'', Faber & Faber, 1947.〕 == Geology == Around 160 million years ago, during the Late Jurassic period, Britain was located further south and was submerged beneath a subtropical sea.〔(Headington ), (Oxfordshire Geology Trust ).〕 The warm conditions meant that coral reefs could flourish. When the coral died, it was buried under successive layers of sediment and other debris. After millions of years, this became fossilized. It formed the Corallian Limestone that is now beneath the Headington Quarry area of Oxford.
