Tabinzurtinsk suite, Eastern Sayan, Russia - Dalmatov and Repina 1971 (Cambrian of Russian Federation)

Where: Russian Federation (49.4° N, 136.4° E: paleocoordinates 13.3° N, 40.4° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Khuzhirtai Formation, Atdabanian (521.0 - 516.0 Ma)

• Specimens occur in the top of the Bokson series (supersuite), comformably on dolomites of the Tabinzurtinsk suite and there is a comformable contact with the superjacent Mangatgol suite. PJW: Tabinzurtinsk is pre-Atdabanian, so this should be Khuzhirtai.
