Also known as Reef 2580
Where: Russian Federation (59.9° N, 31.4° E: paleocoordinates 37.8° S, 0.5° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Baltoniodus navis conodont zone, Dikari Member (Volkhov Formation), Volkhov (471.1 - 469.2 Ma)
• JA: reassigned from the Arenigian to the Dapingian based on conodont zonation. PJW: if this is B. navis zone, then it's the Dikari member, not the Zheltjaki.
• bed-level stratigraphic resolution
Environment/lithology: reef, buildup or bioherm; lithified claystone
Size classes: macrofossils, microfossils
