. Bulletin of the British Museum (Natural History), Geology. 20 W. F. WHITTARD. Fig. 11 Geological map of the area around Snailbeach. Adjoins Fig. 10. 3=Shineton Shales; 4 = Stiperstones Member; 5 = Mytton Member*; 6 = Hope Member; 20 = Silurian rocks; black outcrop D=dolerite. (SJ 30) Although Whittard's notes state that the Lord's Hill Beds 'must not be confused with the fossiliferous beds of Lord's Hill so often mentioned by Salter', he appears to have used the terms in at least partly similar sense. South of the Baptist Chapel at Lordshill, towards Yew Tree Level, and to the north, in the vicinity of Perkins Level, shaly and occasionally flaggy beds overlie the transition beds noted above and have proved fossiliferous at a few places (Locs 145, 148, 897) along the strike; the fauna includes Bergamia rhodesi, Myttonia confusa, Neseuretus parvifrons (Salter), Ogygiocaris selwynii and Redonia anglica Salter. Successively higher beds are encountered westwards along the road from Lordshill to Snail- beach and, to an even greater degree, NW from Perkins Level through Snailbeach Coppice. A dry, right-angled 'gutter' (Loc. 157), possibly a glacial overflow channel, centred c. 250 ft (76 m) west of Lordshill Farm, shows a large exposure in green-weathering, greyish, resistant, gritty flags. Across the valley and at a slightly higher horizon, a small pathside quarry (Loc. 896) c. 500 ft (150 m) NW of Perkins Level shows hard, blocky, jointed siltstones which are cut by a small dolerite intrusion immediately to the south. The beds here and in the adjacent spoil heap at one time yielded fossils including trinucleids, Neseuretus and Ogygiocaris. Other exposures (Fig. 11) in Snailbeach Coppice merit little detailed description but Loc. 891 shows massive quartzitic siltstones, while flags at Loc. 893 are disturbed by doleritic intrusions. The rocks at Loc. 894, a sunken cart-track, are apparently almost at the top of the Mytton Member but do not resemble the lithology of the '
