View looking NNE from above Bergam, 1-3 miles (2-1 km) NNE of Shelve. The quartzites accumulated as coarse-grained, worm-ridden sands with pebbly layers, and comprise a well-sorted deposit generally washed clean of mud. The fact that animal tracks were impressed and preserved suggests that the water was shallow and, indeed, the conditions may have been littoral. The sands were covered by muds for short intervals, particularly during the earlier periods of deposition, but mud and sandy mud became dominant towards the top of the subdivision as Mytton Member conditions became established. Mytton Member Type locality. Mytton Batch, near Snailbeach (Whittard 1960 : 194). First usage. As Mytton Group, by Lapworth & Watts (1894 : 316), later renamed Mytton Flags by Lapworth & Watts (1910 : 752). The term Mytton Group as employed later by Lapworth (1916 : 37) was equivalent to the Stiper Quartzite and Mytton Flags of previous accounts; it was subsequently renamed Mytton Stage by Watts (1925:341), a term employed temporarily by Whittard (1931 : 323), and is now no longer used. Whittard's (1931 : 323, 325) usage of Mytton Flags corresponds to the present Mytton Member. He noted also Lapworth's subdivision of the unit into the following: 4. Tankerville Flags 3. Shelve Church Beds 2. Ladywell & Snailbeach Grits and Flags 1. Lord's Hill Beds. The lowest of these was said to be unfossiliferous but brief notes were given on the faunas of the other three. Later Whittard (1940 : 154; 1952 : 157, table on p. 165; 1953 : 239, 240) used Mytton Flags in a similar sense without further subdivision and, noting Lapworth's thickness of 1600 ft (490 m) as being far too small, gave a figure of c. 3000 ft (915 m). He appears to have been uncertain how to treat the problem of further subdivision because in the fi
