Material.—One fragment of a penultimate order pinna— SNM PMC 2216/54, and two fragments of ultimate order pinnae— SNM PMC 2216/55, SNM PMC 2216/125.

Description.—The axis of the penultimate order is 3 mm wide and longitudinally striated, bears the ultimate order pinnae, up to 4 cm long on one side and to 2–3 cm in other side ( Fig. 5K 1 ). The axes bear spines. One spine is attached to the axis of penultimate order, between the ultimate order pinnae. The other spine is inserted on the axis of the ultimate order, between the pinnules. The spines with the thickened base reach 7–8 mm in length ( Fig. 5R 2 ). The pinnules having a length of 9–12 mm and a width of 3–5 mm are ovate, slightly or not deccurent, incised or dissected into five to seven segments. The segments are lineal, narrow and straight. The midvein is pronounced and runs to the middle of the pinnule. Each segment has a pronounced straight lateral vein.
