Where: Estonia (58.4° N, 22.5° E: paleocoordinates 15.2° S, 1.1° W)
• coordinate based on political unit
• local area-level geographic resolution
When: Rootsikula Formation, Rootsikula (426.2 - 422.9 Ma)
• Rootsikula Horizon. Plotnick gives international age as Ludlovian (evidently following Kaljo 1970, PBDB ref. 7443), but more recent work (e.g. Kaljo and Klaamann, 1982, PBDB ref. 7448) correlates Rootsikula with later Wenlock, and also refers to "Rootsikula Formation" as well as "Rootsikula Horizon".
• formation-level stratigraphic resolution
Environment/lithology: marine; burrowed limestone and burrowed dolomite
