A Ufimia sp. A1 External view of the specimen RAh (101), showing a straight conical corallite with eroded calice rim and apex. Positions of thin-sections indicated. A2–A3 Two successive transverse thin-sections in the mature part of the corallite show the thick, rhopaloid major septa meet in the corallite centre. Scale bars: A1: 5 mm; A2, A3: 2 mm. B Bothrophyllum okense Kossovaya, 2001. B1 External view of the partly preserved corallite (RAh 37), with partly eroded wall. Positions of thin-sections indicated. Successive transverse thin-sections from the lower less mature part in B2 up to the more mature section below the calice in B4, the transverse sections show the axial septum and a very narrow dissepimentarium. Scale bars: 5mm
