Order Cladida Moore and Laudon, 1943 Family Cupressocrinitidae Roemer, 1854

Cupressocrinites sp. ( Fig. 3E ).—The columnals are small, rounded triangular with smooth and slightly convex latus. The articular facet is flat and bordered by a narrow crenularium composed of thick culmina. The lumen is large, trilobate with distinct constrictions in the middle part of the lobes. The columnals are similar to those of Givetian Cupressocrinites inflatus Schultze, 1867 reported from the Loogh Formation of the Eifel Mountains, Germany ( Schultze 1867), and the Portilla Formation of León, Spain ( Breimer 1962), Laskowa Góra Beds and Kowala Formation of the Holy Cross Mountains ( Głuchowski 1993), as well Givetian Cupressocrinites sampelayoi ( Almela and Revilla, 1950) reported from the Portilla Formation ( Almela and Revilla 1950; Breimer 1962) and Laskowa Góra Beds ( Głuchowski 1993), but differ in having more triangular outline and thicker culmina. Le Menn (1988) described similar triangular, rounded columnals with a trilobate axial canal and thin culmina from Frasnian Beaulieu Formation of Boulonnais, France as Trilobocrinus boloniensis Le Menn, 1988 but they may belong to Cupressocrinites .
