Diagnosis
ReferenceDiagnosis
D. B. Blake and R. W. Portell 2009Disk large, interbrachial sinuses broadly rounded, arms probably elongate. Carinal series distinctly enlarged relative to adjacent ossicles; carinals wider than long, with prominent basal facets. Other abactinals approximately equidimensional, faceting distinct only on abactinals near carinals (i.e., disk papulae confined to area above ambulacral columns). Abactinal spines, small pedicellariae alveolae can occur. Interbrachial marginals rectangular, convex, some superomarginals in O. timucum with one or two small spines, remainder of surfaces with subdued, uniform accessory depressions. Marginal side face tissue depressions deep, outer faces bordered by prominent articular facets. Marginal adradial faces faceted for intermarginal, adradial ossicular contacts.
