Where: Russian Federation (54.3° N, 85.9° E: paleocoordinates 31.4° N, 14.5° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Upper Salairka Beds Member (Salairka Horizon Formation), Early/Lower Emsian (409.1 - 402.5 Ma)
• Here are the subdivisions of the Telengitian Stage in type locality. Authors correlate stage roughly with Emsian, but note that the Salairka Horizon is said to correlate with the dehiscens Zone, which, according to Harland et al. 1990 is Pragian.
•JA: the dehiscens zone is actually early Emsian

Environment/lithology: marine; mudstone and limestone
•A: "consists mainly of biogenic-clastic limestone."
• A1: "coral limestones interbedded with siltstones and mudstones containing plant remains"
• A2: "massive reefal limestones" / "biogenic-clastic limestones, locally with coral bioherms"
•B: "composed chiefly of mudstones"
• B1: "interbedded with limestones and richly fossiliferous"
• B2: "barren"
•C: "consists of bedded, platy, clayey limestones locally marked by traces of subaqueous slumping"
•D: "may be equated with a sandy-muddy member with abundant plant remains"
