Kuznetsk Alatau, Kiya River section - Unit V, Subunits 3-6 (Cambrian of Russian Federation)

Also known as Reef 2012

Where: Kemorovo, Russian Federation (56.0° N, 88.0° E: paleocoordinates 11.1° S, 7.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cambrocyathellus aksarinae other zone, Sanashtykgol Member (Usa Formation), Botomian (516.0 - 512.9 Ma)

• Regional stage: Natal'evka; Cambrocyathellus aksarinae zone; PJW: Was Atdabanian, but Cambrocyathellus aksarinae zone (= Torosocyathellus torosus zone) is Botomian. Was Unit V of Ust'kundat, but given the section, this probably should be the Sanashtykgol member of the Usa formation.

• group of beds-level stratigraphic resolution

Environment/lithology: reef, buildup or bioherm; lithified, gray limestone

• Subunits 3-6 consist of light- to dark-gray limestones with solitary bioherms.

Size class: macrofossils
