Basals wedge-shaped, forming externally visible ring (rarely as separated triangles) with small central canal and with pair of interior curved projections that may form a rosette-like structure. Rays divided once at primibrachial 2; arms 10. Proximal syzygies at 3+4, and usually 6+7, 9+10 (unknown beyond 3+4 in Sibogacrinus).Proximal pinnules absent. Arms terminating in long filament composed of slender, elongated brachials lacking pinnules (unknown in Adelatelecrinus and Sibogacrinus) (Modified from Hess and Messing 2011). [details]
