Cobbold's excavation No. 2, Strenuella Limestone, 200 yards south of Comley Quar (Cambrian of the United Kingdom)

Where: England, United Kingdom (52.6° N, 2.8° W: paleocoordinates 86.5° S, 19.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Rhombocorniculum cancellatum small shelly zone, Strenuella Limestone Member (Lower Comley Formation), Branchian (520.0 - 513.0 Ma)

• Matthews (1973: Palaeontology 16(1):139-148) gives this as upper part of Atdabanian.

•Ac4 in Cobbold's (1921) notation.

•Subzone of Protolenellus; this should be Branchian.

• group of beds-level stratigraphic resolution

Environment/lithology: glauconitic, phosphatic, gray, red limestone

• Rushton (1974): shallow-water environment
• reddish-grey limestone (Matthews 1973).
