In the Geological Magazine for December, 1907, a brief account was given by Dr. Henry Woodward, F.R.S., of the work of a small committee of Littleborough and Rochdale geologists, who have for several years been engaged in an examination of the Arthropod Beds at Sparth Bottoms, Rochdale. At Sparth Bottoms several beds of greyish-blue shale, containing clay-ironstone nodules, crop out; the nodules have yielded to the hammer a surprisingly large number of new forms of Arthropoda, some of which have already been figured and described, and others still require further investigation. The beds exposed in the quarry are estimated by the author as 135 to 180 feet above the Royley Mine Coal Seam.
