Brora Beds are a series of strata occurring at Brora, a village in Sutherlandshire, of the same age as the Inferior Oolite of Yorkshire. They are chiefly remarkable for the occurrence in them of a seam of coal of good quality feet thick, being the thickest stratum of true coal hitherto discovered in any secondary strata in Britain.
