Where: Russian Federation (54.3° N, 85.9° E: paleocoordinates 30.7° N, 17.5° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Lower Shanda Beds Member (Shanda Horizon Formation), Late/Upper Emsian (402.5 - 391.9 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: originally entered as Emsian; the serotinus zone is late Emsian

Environment/lithology: marine; argillaceous 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"
