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:
“The poppy that my heart was,
formed to bind all mortals,
made to strike and gather hearts
like flame upon an altar,
fades and shrinks, a red leaf
drenched and torn in the cold rain.”
—Hilda Doolittle (1886–1961)
“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)
