Abundant sigmas (I and II) appear to be randomly distributed. Toxiform microxeas were not recognized. Spicules (Fig. 4 C–I). Tylostyles (286– 392.5 –521 x 3 – 8.1 –14 µm, length x width): long, thin, erect and smooth (Fig. 4 C–D); Sigmas I (19– 29.8 –38 µm, chord length) and Sigmas II: (9– 11.6 –14 µm, chord length) thin, abundant and terminally microspined (Fig. 4 F, G, I); Toxiform microxeas (54– 76.7 –90 µm, length) long, thin, curved and microspined (Fig. 4 E, H).
