FIGURE 7. Taphonomic residues of Hydroides elegans from mollusc shells collected in the Great Bitter Lake in 1950 by C. Beets. The chitinous residues "survived" more than 50 years in the dried serpulid tubes. A—Body of dried worm, B—Thoracic chaetae, C—Broken but distinctive collar chaetae, D—Residue of verticil, E—Fragment of tube with adhering fascicles of thoracic chaetae (putative identification of species based on tube), F—Thoracic uncini (putative identification to species based on tube), G—Operculum, apical view of verticil, H—Operculum, ¾ view. I. Tube with projecting verticil, lower side of tube. J. Hydroides elegans tube fragment on shell of Gafrarium pectinatum, K—Fusinus polygonoides shell (ca. 11 cm in length), bearing tubes of H. elegans. Scales: A, B, D, E, I, J—1 mm; G, H—100 µm; C, F—50 µm. Figs A, B, D–F, I, K—from Beets' Stn 4, 0.2–0.8 m, C, G —from Stn 21, 1.5–3 m, H—from Stn 1: 1–2.7 m, J—from Stn 19: 5–5.5 m (for stations, see Beets (1953), Appendix Table 2B).
