Where: Russian Federation (79.2° N, 97.3° E: paleocoordinates 22.7° S, 1.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Kurchavinskaya Formation, Iverian (494.0 - 489.5 Ma)

• STRATIGRAPHIC RELATIONS: Cambrian Kurchavinskaya Fm is overlain unconformably by the Kruzhilikha Fm. Stratigraphy is described in more detail by Makarev et al. (1981) and Bogolepova et al. (2001). THICKNESS: 100 m to 250 m in thickness locally. AGE: Iverian. Correlated to the Protopeltura praecursor Biozone of the standard Baltic sequence. The upper part of the Kurchavinskaya Formation has been previously corelated with the upper half of the upper Cambrian, equivalent to most of the Iverian and the Payntonian stages of the Australian succession. The present series of collections contain taxa (e.g. P. holtedahli) that indicate correlation with the Ketyi horizon, and hence correlation into late Iverian of Australia.
