Haplocrinites sp. ( Fig. 3C, D ).—The aboral cup is wide and cupuliform with pentagonal outline in oral view. Radial facets are narrow, trapezoidal. Oral pyramid is as high as the calyx. The external surface of the oral plates is flat. The thecae are most similar to Haplocrinites stellaris ( Roemer, 1844) reported from Givetian–Frasnian Red Iron Horizon of the East Sauerland, Germany ( Roemer 1844; Sandberger and Sandberger 1850 –1856), but differ in having a relatively less elevated oral part. They differ from Haplocrinites gluchowskii Hauser, 2002 reported from Late Frasnian Detrital Beds of the Holy Cross Mountains ( Głuchowski 1993), Upper Wallersheim Dolomite of the Eifel Mountains, Germany ( Hauser 2002) and the Neuville Formation of the Dinant Basin, Belgium ( Hauser 2003) in having distinctly less prominent radial facets.
