Figure 6.1-6.19. 1. Lobatula lobatula (Walker and Jacob). Attached and impaled, growing planispirally; does not tend to wrap itself on the meshwork. Shipek grab TUL99A016, sponge fraction. 2-3. Lobatula mckannai (Galloway and Wissler). Attached and impaled. Slight tendency to wrap itself on the meshwork. 2. side view. 3. spiral side. Shipek grab TUL99A014, sponge fraction. 4-5. Lobatula mckannai (Galloway and Wissler). Attached and impaled, wrapping itself over the meshwork. 4. general view. 5. close-up of spicule "piercing" spiral side wall (at lower right on Figure 6.4). IKU subcore TUL99A06, 6-9 cm, 63-1000 µm. 6-7. Lobatula lobatula (Walker and Jacob). Originally attached, shows notches in test due to presence of spicules. 1. general view. 2. close-up of a notch. Shipek grab 99A014, sponge fraction. 8-10. Lobatula lobatula. Various angles on a specimen that grows impaled on (or through) meshwork with minimal disturbance of its planispiral growth form. Shipek grab 99A016, sponge fraction. 11-12. Lobatula mckannai. Umbilical (11) and side (12) views on a specimen that grows on meshwork. Its attached face wraps itself over the substrate. IKU grab sample TUL99A07, surface subsample (99A07 "forams"), sponge fraction. 13. Lobatula lobatula. Attached to meshwork, but with a flat spiral face. Shipek grab TUL99A015, sponge fraction. 14. Lobatula cf. lobatula. Attached and impaled, with a tendency to wrap itself over the meshwork. Shipek grab TUL99A016, sponge fraction. 15. cf. Lobatula lobatula. Attached, trapped and contorted. Grab sample TUL99A015, sponge fraction. 16-17. Two sand grains trapped in lattice. Grain in 16 is partly covered by mud leftover from incomplete washing. Both grains are on the same sponge fragment. Slurp gun sample SLRP4772, sponge fraction. 18. Hyalinonetrion dentaliforme (Bagg). Somewhat etched and dirty specimen found inserted in a succession of cells in the rectangular meshwork of a Farrea occa. Was removed with a wet brush but is considered trapped. Slurp gun sample SLRP4771, sponge fraction. 19. Reophax scorpiurus Montfort, trapped in meshwork. Slurp gun sample SLRP4775, sponge fraction. 20. Reophax sp., trapped and impaled. Grab sample TUL99A019, sponge fraction. 21. Saccammina sp. 2. Attached on meshwork. Grab sample TUL99A016, sponge fraction. 22. Recurvoides cf. turbinatus (Brady). Apertural view. Slurp gun sample SLRP4772, <1 mm.
