- FIGURE 4. Pandanipora helix n. gen., n. sp. Details of morphology. A, specimen YMG4–13, Stn 289; B–D, paratype 4, ZIRAS 5/50671; E, paratype 5, ZIRAS 6/50672; F, G, Q, paratype 1, ZIRAS 2/50668; H, specimen GLD4–11, Stn 217; I, holotype, ZIRAS 1/50667; J, specimen YMG4–06, Stn 68; K, O, specimen YMG4–13, Stn 321; L, specimen YMG4–13, Stn 295; M, paratype 2, ZIRAS 3/50669; N, specimen GLD4–12, Stn 258; P, specimen GLD4–12, Stn 255. A, distal view of growing edge of colony showing early differentiation of daughter zooid and prop from the floor of the parent zooid, with chambers arranged in stacks; B, growing edge of colony showing differentiation of a daughter zooid (lower) from the floor of the parent zooid (upper); C, same, close-up; D, interior surface of developing zooid chamber showing imbricated foliated fabric of wedge-shaped crystallites and openings of pseudopores; E–I, variability of zooid size and geometry: E, elongated zooids with tall peristomes; F, part of ring-like colony; G, lateral view of same colony, two zooids near-perpendicular to plane of props; H, arcuate colony with overlapping peristome bases; I, lateral view of apical coil of spiral colony with subconnate peristome bases and shortened peristomes, most broken; J, frontolateral view of tubular peristome showing annular striae on the surface; K, lateral view of tubular peristome; L, peristomial aperture, frontal view; M, oblique view of peristomial aperture showing imbricated foliated fabric of wedge-shaped crystallites and interior openings of pseudopores; N, imbricated foliated fabric of wedge-shaped crystallites around internal opening of pseudopore; O, zooidal wall showing tiny sparse simple pseudopores; P, Q, close-up of zooidal wall showing crystallites. Scale bars: A, B, G, 250 μm; C, J, K, O, 100 μm; D, N, 10 μm; E, F, H, I, 500 μm; L, M, Q, 50 μm; P, 15 μm.
