| Eurypterid-Associated Biota of the Rootsikula Horizon, Saaremaa, Estonia | Plotnick R. E. (1999) | Rootsikula | 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". | "limestone" | 426.2 - 422.9 Ma
