Embryos and polyps of Olivooides. (a) Cleavage-stage embryo (GMPKU3080). (b) Stellate embryo with raised apertural rays (GMPKU3081). (c) Stellate embryo with a raised apertural region (GMPKU3082). (d) Stellate embryo with an infolded apertural region (GMPKU3084). (e–f) Stellate embryo showing a characteristic pattern of bulges in (e) lateral, and (f) apertural aspect (GMPKU3083). (g) Embryo within fertilization envelope that preserves the characteristic pattern of bulges, but not the stellate tissue (GMPKU3085). (h–j) Early post-embryonic polyp stage exhibiting characteristic stellate integument of embryonic stage, but exhibiting the annulated striated adapertural tissue, and the pentamerally enfolded aperture, in (h) lateral, (i) apertural and (j) oblique aspects (GMPKU2317). (k) Later polyp-stage specimen in lateral aspect (GMPKU3086). Scale bars: (a) 69 µm, (b) 116 µm, (c) 139 µm, (d) 125 µm, (e,f) 132 µm, (g) 164 µm, (h) 275 µm, (i) 118 µm, (j) 250 µm, (k) 262 µm.
