The Old Red Sandstone is a British lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. For convenience the short version of the term, ORS is often used in literature on the subject. The term was coined to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain.

Famous quotes containing the words red and/or sandstone:
“To motorists bound to or from the Jersey shore, Perth Amboy consists of five traffic lights that sometimes tie up week-end traffic for miles. While cars creep along or come to a prolonged halt, drivers lean out to discuss with each other this red menace to freedom of the road.”

“But the lightning which explodes and fashions planets, maker of planets and suns, is in him. On one side elemental order, sandstone and granite, rock-ledges, peat-bog, forest, sea and shore; and on the other part, thought, the spirit which composes and decomposes nature,—here they are, side by side, god and devil, mind and matter, king and conspirator, belt and spasm, riding peacefully together in the eye and brain of every man.”
—Ralph Waldo Emerson (1803–1882)
