Material.—A single specimen (TUG 1395−8) is known from Estonia.

Discussion.—Only the proximal portion of one specimen of Calliocrinus sedgwickianus Angelin, 1878 is recognized from Estonia. However, this specimen had long, robust spines (now broken) projecting outward from both the basal and radial plates ( Fig. 3B View Fig ). This resulted in a distinctive pattern that characterizes only a few species of this genus. Although this specimen is heavily bored with Oichnus Bromley, 1981 , it is evident that a single ridge projects from the base of the basal plates toward the column attachment, which is characteristic of C. sedgwickianus (see Angelin 1878: pl. 1: 3).

Geographic and stratigraphic range.—This taxon was identified from the Middle Äigu Beds, Kaugatuma Formation at Kaugatuma Cliff, Saaremaa, Estonia.
