(TEM). A: Scrippsiella trochoidea (GeoB*185, early coccoid cell, the theca is still attached; note the intravacuolar vesicles). B. Scrippsiella trochoidea (GeoB*185). C. Scrippsiella aff. trochoidea (GeoB 283, note the lysozymes as intravacuolar membrane whorls). D. Scrippsiella aff. trochoidea (GeoB 283, note the lysozymes as intravacuolar membrane whorls). Abbreviations: cb, crystal-like particle; ch, chloroplast; ix, inner matrix; ly, lysosme; me, unit membrane; th, thecal plate. Scale bars: 1 µm.
