Figure 8. Morphotraits of Spongillida gen. sp. (cf. Pottsiela; BMNH 23.10.7.1 partim; FW-POR 429). See Figure 6. Microphotographs of gemmules and spicular complement morphotraits. (A) gemmular theca with outer layer armed by spiny oxeas/strongyles/strongyloxeas as tangential gemmuloscleres irregularly arranged. (B) gemmules sharing the outer layer. (C) dense gemmuloscleres tangentially arranged at the outer surface. (D) gemmular theca (cross-section) with multilayered gemmuloscleres (pneumatic layer is absent). (E–G) smooth oxeas as skeletal megascleres (A–D, SEM; E–G, LM).
