Description
Summary:Figure 6. Typical Trilobatus trilobus and intergradation with Trilobatus immaturus. A–O, Trilobatus trilobus (Reuss, 1850); P, Trilobatus immaturus (LeRoy, 1939). A–K, GLOW-3, south-west Indian Ocean (A, D, E, G, I, spiral view, in D note no spine holes are visible due to gametogenic calcite; B, F, H, J, K, umbilical view, in F note thick gametogenic calcite obscuring sacculifer-type wall texture on penultimate chamber; C, detail of coarse sacculifer-type wall texture and abundant spine holes at intersections of interpore ridges); L, M, ODP Site 926, Ceara Rise, western tropical Atlantic, 11H/04/50–52 cm (umbilical view); N, O, ODP Site 871, Limalok Guyot, Marshall Islands, equatorial Pacific 3H/03/60–62 cm (N, umbilical view; O, detail of gametogenic calcite, no spine holes visible). P, ODP Site 871, Limalok Guyot, Marshall Islands, equatorial Pacific 3H/03/60–62 cm (umbilical view; note final chamber not dominant over previous chambers, compare with A–O). Scale bars = 100 Lm, except for close-up images C and O, where scale bars = 20 Lm.
