Noriphyllia

Roniewicz and Stanley 2009, p. 470

Earlier, in Roniewicz, E., Stanley, G.D., Jr., Da Costa Monteiro, F. and Grant Mackie, J.A., 2005: 300, described as Margarophylliid indet..

Type Species

Noriphyllia anatoliensis Roniewicz and Stanley, 2009, p. 472, figs. 1A-F, 2B-E, 3A-F; Original Designation Roniewicz and Stanley, 2009, p. 470

Type Specimen: Holotype; UMPC 401380; Verified; Dry Preserved

Type Locality: Near to locality Dereköy, Alakir Çay Valley, Taurus Mountains, Anatolia Turkey, Lower Norian, Stikinocers kerri Zone, Triassic

Diagnosis

Solitary, conical, Calice open. Axial fossa short. Septa straight, densely arranged; septa of the first three-four orders subequal in thickness. Septa of the highest order hidden in the wall. Rare lonsdaleoid septa of the S4 order are observed. Lateral septal micromorphology in the form of small, sharp granules. Wall septothecal with addition of epithecal stereome. Dissepiments small, vesicular, abundant.

Description

Described and figured in Roniewicz and Stanley (2009) with presentation of microstructure in fig. 2B-E, and fig. 3A-F, and its comparison with microstructure in Distichophyllia (fig. 3G), Retiophyllia (fig. 3H) and Margarophyllia (3 I, J).

Comparisons

From the most similar Coryphyllia it differs, primarily, in having zigzag mid-septal zone and lateral stereome organized into well individualized lateral fascicles of fibers, and in a wall composed of septa of the last size order covered with epitheca.

Remarks

Together with the type species, two other species were described: N. dachsteinae Roniewicz and Stanley 2009 from the Lower Norian (Epigondolella quadrata Zone), Dachsteinplateau, Northern Calcareous Alps, and N. monatutoensis Roniewicz and Stanley, 2009, from the Carnian of Timor-Leste.
