Old Red Sandstone, abbreviated ORS, is an assemblage of rocks in the North Atlantic region largely of Devonian age. It extends in the east across Great Britain, Ireland and Norway, and in the west along the eastern seaboard of North America. It also extends northwards into Greenland and Svalbard. These areas were a part of the paleocontinent of Euramerica (Laurussia). In Britain it is a lithostratigraphic unit (a sequence of rock strata) to which stratigraphers accord supergroup status and which is of considerable importance to early paleontology. The presence of Old in the name is to distinguish the sequence from the younger New Red Sandstone which also occurs widely throughout Britain.

New Red Sandstone in the context of Mid Severn Sandstone Plateau
The Mid Severn Sandstone Plateau is a rural landscape and one of the natural regions of central England, straddling the border between the counties of Shropshire and Staffordshire. It stretches from the western fringes of the Birmingham conurbation to Telford in the north and Kidderminster in the south. The major feature of the plateau is the valley of the River Severn, which cuts through it from north to south. It consists of Permian and Triassic-age New Red Sandstone getting older as one goes west until one reaches Silurian and Carboniferous-age siltstones and coals west of the river.
