Also known as Doarrovárri

Where: Troms, Norway (68.6° N, 19.6° E: paleocoordinates 44.9° S, 12.3° W)

• coordinate based on nearby landmark

When: F3 Member (Torneträsk Formation), Early/Lower Cambrian (538.8 - 509.0 Ma)

• "Member F 3 (Vogt 1967)", in Ahlberg (1980). Sequence LC2-3 according to Nielsen & Schovsbo 2011. Axelberger et al. (2007) make this the uppermost member (Upper Siltstone Member) the Torneträsk formation. However, Nielsen & Schovsbo (2011) make this member its own formation, the Grammajukku. That overlies the Torneträsk and underlies the Alum

• member-level stratigraphic resolution

Environment/lithology: calcareous shale and limestone

• "...calcareous bed (member F 3, Vogt 1967) on top of a sequence of shales underlying the alum shales. This fossiliferous impure limestone has a maximum thickness of l. 7 m, and it is regarded as the top of the local Lower Cambrian

•(Vogt 1967: 14 ).", in Ahlberg (1980)

Size classes: macrofossils, mesofossils
