Figure 14. Details of mantle edge morphology in Pulvinites exempla (scanning electron microscopy; AMS C.129659, 62.2 mm). A, cross-section of the mantle; the arrow shows OF-2 (pallial skirt) (scale bar = 200 µm). B, lateral view of the interior mantle margin showing the outer surfaces of IF-1, IF-2, and OF-1; the arrow indicates the sinuous groove separating the inner fold (scale bar = 200 µm). C, magnified large tentacle of the inner surface of IF-1 (scale bar = 25 µm). D, small laterally compressed tentacles of the outer surface of IF-2 (scale bar = 50 µm). E, ciliated inner surface of IF-1 (scale bar = 10 µm). F, smooth inner surface of OF-1 (scale bar = 10 µm); IF, inner mantle fold; OF, outer fold; p, periostracum; t, tentacle.
