Catalog entries: Stylodictya ocellata
x: S. ocellataOriginal description: discus gyrose annulalus spiralis, media cellula parva gyrorum poris, mediis parvis externis valde et eleganter ampliatis crebris, spinis radiantibus prope medium a tenui radicula in aculeos crassos increscunt. Specimen mancum. Aculei 2 (fere 4).
Translated description: Disc spirally ringed, with a small median chamber, and porous whorls, the pores of the median ones small and those of the external ones much wider, elegant and dense; with radiating spines originating near the middle as thin rods and increasing outward to thick spines. Specimen incomplete. 2 (approx. 4) spines. (Translated from Latin by E.M.R. and W.R.R.)]
Petrushevskaya and Kozlova 1972 - Stylodictya ocellata Skeleton is irregularly quadrangular, consisting of 3-4 systems; width of the cupolas is relatively large, especially in the last systems; zig-zag radial lines are clearly expressed, pores are round. On the first system pores are half the size of most on the others; there are 3-4 pores on the width of a cupola. Four rather thick and long, three-bladed spines are arranged at right angles. Disc diameter 140-170, width of cupolas 12µ (first system), 40µ (fourth system); pore diameter 7-8µ, in the first system 3µ; length of spines exceeds 100µ. Oligocene.
