WOOLVERSTONE, SUFFOLK.

In a geological account of the area a coprolite working was noted in 1882 at the foot of the red crag by the roadside just northwest of Freston Tower. The ten inch nodule bed was found just over eight feet of sand and crag but there was no indication who was responsible for the operation. (Whitaker, The Geology of Ipswich, 1885, p48)
