Description

Figure 10. A, B, Monoporella multilamellosa (Canu & Bassler), Eocene, North Carolina, USA, NHM BZ4860. A, complete ovicell consisting of two flattened and expanded spines overgrown distally by a narrow fringe of cryptocyst; note lateral foramina. B, broken ovicell exposing gymnocystal floor and showing the medial gap between the bases of the two ovicell spines. C-F, Monoporella sp. 2, Recent, Alaska. C, bleached colony fragment with two complete ovicells and lateral foramen arrowed; MNHN 2856–7(b). D, unbleached ovicell; MNHN 2856–7(a). E, broken costa showing coelomic lumen; MNHN 2856–7(b). F, oblique view showing gymnocystal internal surface of ovicell; note limit of the cryptocystal expansion from the outer ovicell surface, and longitudinal grooves; MNHN 2856–7(b). Scale bars: A, B, E, F = 100 Mm; C = 500 Mm; D = 200 Mm.
