Diagnosis
ReferenceDiagnosis
D. B. Blake and R. W. Portell 2009Ocalaster with small pedicellariae alveolae on some abactinals, possibly concentrated near ambulacra; abactinal spines occur. Superomarginal profile low, adradial margin rounded; adradial terminus appears to extend beyond that of IM. Shallow peripheral furrow zone probably present between marginal series. One or two transversely aligned circular spine bases on some SM, most bases near transverse ossicular midline and near abradial edge but bases can be more adradial, offset from midline. IM side face outline nearly rectangular. Side face-adradial face edge with distinct facet dorsally.
