... of the ca. 950–900 Ma (Re-Os minimum age constraint = 898 ± 68 Ma) Dolores Creek Formation in the Wernecke Mountains, northwestern Canada. These fossils, variably preserved by iron oxides and clay minerals, represent two size classes. The larger forms feature unbranching thalli with uniform cells...

Siphonophycus robustum , Knoll, A.H., Swett, K., Mark, J., 1991 ( Fig. 4 E) Description: These are thin, tubular, unbranched, cylindrical; non-septate may be straight or sinuous filaments with smooth wall, unornamented and circular to elliptical cross - sections. Diameter of tubes ranges from 2 - 6 μm...

.... The formation on West Falkland is c . 2560 m thick and consists of five members: Plantation, Albemarle, Mount Alice, South Harbour and Fish Creek. Thirty-five lithofacies are defined using variations in grain size and bedding characteristics. The distribution of these lithofacies and their associated...
