Diagnosis
ReferenceDiagnosis
R. V. Kesling 1962 (Protopalaeasteridae)Phanerozonia with the ambulacrals in each of the five arms set so closely that the openings for insertion of ampullae are either very constricted or completely inadequate. First inframarginals (axillaries) marginal. Madrepore plate well developed, aboral. Disk heavy plated. No accessory plates or ossicles in the arms.
J. Dean Shackleton 2005Marginals occur in two series - inferomarginals plus superomarginals; primary radials enlarged with respect to remaining radials; primary radials and primary interradials meet at apices forming a ring; circumorals and mouth angle plates meet at an obtuse angle; axillary larger than adjacent inferomarginals.
