Material.— GIT 240−16, GIT 240−17, GIT 240−26, GIT 240−29, GIT 240−37, and GIT 240−38 from the Jaagarahu Formation, Ikla Core; GIT 240−18 from the Paprenjai Formation, Kakvaruja Core; GIT 240−23 and GIT 240−27 from the Ohesaare Core; GIT 240−25, GIT 240−30, GIT 240−33, GIT 240−34, GIT 240−35, and GIT 240−36 from the Kalvarija Core; GIT 240−31 from the Häädemeete 172 Core (see Rozhnov and Männil in Rozhnov et al. 1989).

Discussion.— Pisocrinus (Pisocrinus) pilula is a well−known and geographically widespread pisocrinid and the type species for Pisocrinus . Rozhnov and Männil in Rozhnov et al. (1989) reported it from the following cores: Häädemeete 172, Ikla, Kalvarija ( Lithuania), and Ohesaare. In Estonia, it occurs exclusively in the Jaagarahu Formation and in Lithuania in the Paprienis Formation (Sheinwoodian). For a complete synonymy and discussion for this species, see Donovan et al. (2009).

Geographic and stratigraphic range.—This taxon is reported from Wenlock through Ludlow strata from Asia, Czech Republic, Estonia, Lithuania, Poland, Russia, Sweden (Gotland), and the United Kingdom. In Estonia, it is in the Jaagarahu Formation.
