Diagnosis
ReferenceDiagnosis
J. K. Rigby 1983Subconical to oval, thin-walled, protosponge with diagonally oriented stauracts. Sponge has a somewhat rounded base and wide osculum. Sponge body 25–90 mm in height and 15– 45 mm in maximum width. Stauracts are regularly spaced 1.5–3 mm apart to form rhombic quadrules. Each quadrule appears to be formed by two (rather than four) first-order stauracts. First-order stauracts have ray diameters of 0.03–0.05 mm and ray lengths about 2.5 mm. Second-order stauracts occur in quadrules. No marginalia or prostalia are preserved. The Hetang specimens are closely similar to Diagoniella cyathiformis from the Middle Cambrian Wheeler Shale and Marjum Limestone (Rigby, 1978, 1983).
