Diagnosis
ReferenceDiagnosis
O. Fatka and V. Kordule 1990Eocrinoids with irregular multiplated cylindrical to conical theca; aboral portion of theca ( = calyx and holdfast) composed of adorally imbricate plates without epispires; oral surface composed of adjacent plates bearing large epispires. Ambulacral system confined to oral surface, composed of unbranched biserial brachioles, probably five in number.
M. Nohejlová et al. 2019Body wall composed of two
parts – aboral cup and oral surface. Cone-shaped aboral
cup composed of adorally overlapping imbricate plates,
without epispires. Flattened tessellate oral surface made
of numerous adjacent polygonal plates, bearing epispires.
Curved ambulacra showing a 2-1-2 pattern, extended over oral surface toward lateral edge. Coiled brachioles mounted unilaterally to ambulacral ray. Mouth close to centre of oral surface.
