Diagnosis
ReferenceDiagnosis
J. W. Durham 1967
Comparatively slender, fusiform helicoplacoids with short, mostly highly spinose medial interambulacral plates; ambulacra complex, medial plates slender and very numerous.
J. W. Durham 1993Helicoplacida with tubefeet emerging between sequential ambulacral plates (see Durham, 1967, text-fig. I; Fig- ure 3.3 herein), and 12 interambulacral areas involution adoral to primary ambulacrum.
B. C. Wilbur 2006Helicoplacoids with a rhombus-shaped plate at the intersection of the distal corners of floorplates and proximal corners of primary coverplates. Faces of interambulacral plates are pentagons with the acute end directed away from the animal.
