Borehole Vostok 3, Raiga Formation (Ediacaran of Russian Federation)

Where: Tomsk, Russian Federation (59.4° N, 85.7° E: paleocoordinates 32.2° S, 15.1° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Nama other zone, Raiga Formation, Ediacaran (635.0 - 541.0 Ma)

• depth interval 4191-3870 m; PJW: Put in Vendian, but also in the Nemakit Daldynian, which had not yet been annexed by the Cambrian. PJW: So, it seems that they are using two Nemakit Daldynian's: a stage and a horizon. The *horizon* is basal Cambrian, as is the upper half of the stage. The lower half is Ediacaran

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified limestone

• 3 cycles of clastic limestones with interlayers of sandstone, siltstone and mudstone

Size class: macrofossils

Collection methods: core,
