Figure 3. Ossicles from the holotype and a paratype of Calcamariina hibberdi O'Loughlin & Skarbnik-López sp. nov. (holotype NMV F165750, paratype TMAG H3542). a, SEM images of variably knobbed and thickened plate fragments from the ventral body wall and papillae, with some marginal spines (from holotype); b, microscope photos of large body wall plate with smooth perforated base and knobbed projecting distal end that has lost its distal spinous edge (top, from holotype; scale bar refers to this ossicle only), and two tube foot/papilla support plates with projecting outer marginal spinous edge (bottom, from paratype; up to about 140 µm long; scale bar does not refer to these ossicles), and; c, SEM images of small perforated, concave plates (top), curved plates, rod and rod-plates from a tentacle (from holotype).
