Cobbold's excavation No. 2, Protolenelus Limestone, 200 yards s. of Comley Quarr (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: Protolenus trilobite zone, Protolenus 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.

•Ac5 in Cobbold's (1921) notation.

•This should be Branchian given zonation.

• group of beds-level stratigraphic resolution

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

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