Figure 7.1-7.19. 1-3. Trochammina sp. 3. 1. spiral side. 2. umbilical side. 3. oblique view showing aperture. Slurp gun sample SLRP4772, <1 mm. 4. Portatrochammina bipolaris (Brönniman and Whittaker). Oblique view showing aperture and flaps. Slurp gun sample SLRP4772, <1 mm. 5-6. Attached trochamminid, growing deformed inside the meshwork. Two views of the same specimen. Slurp gun sample SLRP4771, sponge fraction. 7-9. Trochammina sp. 2. Three views of the same specimen detached by wet brush from the meshwork on which it had grown. Shipek grab TUL99A017, >1 mm. 10. Trochammina sp. 2. Spiral side view of specimen that has grown and trapped itself into the meshwork. Slurp gun sample SLRP4771, sponge fraction. 11-13. Trochammina sp. 5. 11. Umbilical view. 12. Spiral view. 13. Oblique view showing aperture. Shipek grab TUL99A017, sponge fraction. 14. Trochammina sp. 5, umbilical view of attached (impaled) specimen with scar due to meshwork. Shipek grab TUL99A018, sponge fraction. 15. Trochammina sp. in meshwork. It is not clear whether it is attached or trapped or even loose. Shipek grab TUL99A017, sponge meshwork. 16. Islandiella californica (Cushman and Hughes). Small (young) specimen, well-preserved, not from a sponge. Piston core sample TUL99A09, 167-170 cm, <1 mm. 17. Globocassidulina subglobosa (Brady). Aperture partly obstructed by glue. Piston core sample TUL99A09, 167-170 cm, <1 mm. 18-19. Two views of a deeply etched cassidulinid (I. californica?), showing deep scar due to presence of meshwork. Specimen formerly impaled. Triggerweight core sample TUL99A010, 85-88 cm, >1 mm. 20-21. Deeply etched cassidulinid (I. californica?), trapped but probably not impaled. 20. general view. 21. close-up of etch marks. Slurp gun sample SLRP4771, sponge fraction. 22. Indeterminate (Islandiella californica?) etched and trapped juvenile cassidulinid. Some spicules have been broken away to show foraminifer. Shipek grab TUL99A014, sponge fraction. 23-24. Islandiella californica, trapped and well preserved. 23. aboral side. 24. oral side. Slurp gun sample SLRP4775, >1 mm.
