(Figures 4E, 9A) and Pliocardia stearnsii, the lucinid Lucinoma aequizonata (Figure 9D), and the thyasirids Thyasira flexuosa (Figure 9E) and Axinopsida serricata (Figure 9F). Other articles where Serpulidae is discussed: feather-duster worm: …the closely related polychaete family Serpulidae. (2012). We suggest that the serpulid tube facies formed in situ, and that the vast aggregation of these tubes at Fossil Hill is likely due to a combination of optimal physical environmental conditions and chemosynthetic production, which may have been particularly intense as a result of sea-level lowstand during the Last Glacial Maximum. Figure 3. Description. Microscopic evidence of serpulid affinities of the problematic fossil tube Serpula etalensis from the Lower Jurassic of Germany. Proc. The radiocarbon ages of the tubes approximately coincide with the last glacial maximum (LGM; 20 cal ka BP), during which sea-levels are estimated to have been 110–130 m lower than at present (Lambeck and Chappell, 2001; Bintanja et al., 2005). Additional fossil taxa associated with the fossil serpulid tubes were examined using a combination of light and scanning electron microscopy, using an FEI Quanta 650 FEG-ESEM at the University of Leeds, Leeds, United Kingdom. The composition of four tube fragments was analyzed using fourier transform infrared spectroscopy (FTIR) to determine the form of calcium carbonate present in the tubes. Earth Planet.

R: A Language and Environment for Statistical Computing. In order to determine a site-specific correction for Fossil Hill, the U-Th composition of five sediment samples from four vibracores collected during dive DR630 was analyzed. However, the proportion of the seafloor that has been explored with tools and techniques that allow features like this to be identified is still very small. Front. These worms can hence function as important ecosystem engineers, altering local hydrodynamics, and providing habitat structure utilized by other marine organisms (Schwindt et al., 2001), but can also accumulate to foul marine structures and modify ecosystems within which they are invasive. I would say that the serpulid could be fossilized (although I'm not sure at all). In some serpulid worm tube-rich samples, they occurred as geopetal structures, indicating the tubes were horizontal to the palaeo-seafloor while they were being mineralized and after the death of the worms forming them.

Rev. The tubes ranged from 1 to 7 mm in diameter (mean = 3.5 mm, n = 219; (Supplementary Table S1), very small tubes up to 1 mm in diameter were occasionally observed, and several were found attached to larger tubes (Figure 7C). The other (DR631) is within a ∼1.6 km long and >350 m wide area located 7.9 km northwest of Fossil Hill on the north side of Santa Monica Canyon in 509–530 m water depths, and lying on the extension of the same ridge (Figure 1B).

Maybe try looking for signs of matrix inside the serpulid? The δ13CV PDB values of the same samples ranged from -18.06 to -11.01‰. Video footage from a systematic ROV flight during DR627 was used to construct a video mosaic of a sub-region of the Fossil Hill mound (Figure 1). (A) Isopachous fibrous aragonite cement (ifa) and peloidal micritic sediment (ps) forming geopetal fill within shelter cavity formed by articulated vesicomyid bivalve shell (bs), plain polarized light, sample DR630 R-3, and scale bar is 200 μm. Bull. Serpulid Worm Tube Cambrian Utah. All U-Th data are listed in (Supplementary Table S3), with a selection of dates considered accurate presented in Table 2. Commun. While Fossil Hill is located in close proximity to the base of the Santa Monica Canyon (Figure 1), the mound is situated over 500 m from the main channel in a part of the seabed unlikely to be influenced by canyon transport processes. Neither gas bubbles or gas hydrates were observed during the ROV explorations. U-Th dating of cements on bivalve shells from specimens collected on the northern end of Fossil Hill produced ages of approximately 7.1 ka, while carbonate cement on fossil bivalve specimens from the DR630 dive site yielded an age of 20.8 ka (Table 2).

The epithet feather-duster refers to the multicoloured crown of finely divided tentacles that are attached in two groups, one on either side of the… We interpret all of the tubes as belonging to the same species, as significant differences between them were not observed (smaller differences could be due to intraspecific variation and the observed presence of a range of ontogenic stages), and as dense serpulid settlement is often dominated by a single taxon. Please report any problems. While serpulids can occur in large numbers at deep-sea seeps (Olu et al., 1996a,b; Levin et al., 2012; Amon et al., 2017), they rarely construct sizeable reef structures below the photic zone.

Methane hydrates and global climate. Sabellids live in long tubes constructed of mud or sand cemented by mucus, whereas serpulids build tubes of calcareous materials. The current topography of Fossil Hill (Figure 1C) appears to be largely a result of differential erosion which has exposed authigenic carbonates and vast quantities of serpulid tube fossils, and this process is likely also responsible for exposing similar facies ∼8 km to the northwest, and ∼300 m to the southeast along the same fault zone as Fossil Hill. Petrographic thin section images of Fossil Hill seep carbonates. No living serpulids with equivalent tube morphologies were found at the site; hence the mound was termed “Fossil Hill.” In the present study, the identity of the fossil serpulids and associated fossil community, the ages of fossils and authigenic carbonates, the formation of the fossil serpulid aggregation, and the geological structure of the mound are explored. London: Graham and Trotman. (2005). Program and User’s Guide. This geometry reveals that the Fossil Hill deposit and the southeastern outcrop continue into the subsurface.

Like all serpulids, each protected its soft body by producing coiled tubes made of … The AUV survey of the Fossil Hill site was repeated in April 2018 (AUV dive 201807m1) following improvement in processing software. (2016), as well as additional mollusk identifications. A lot of time and skill has gone into preparing this so it is in relief from the matrix. However, there is a problem – worms are recognized by the morphology of their soft bodies. The latter species is described from eastern Pacific hydrothermal vents and can have substantial unattached tube portions with a circular cross-section, however, comparison of these sections with those of Fossil Hill tubes revealed differences in the smoothness of the outer tube wall, as well as degree of undulation of the keels. The Museum’s collection of fossil annelids is both geologically and geographically diverse. Nobuhara, T., Onda, D., Kikuchi, N., Kondo, Y., Matsubara, K., Amano, K., et al. They are all examples of New Zealand fossils, and the images are copyright-free. U-Th dating of MDAC cements on tube surfaces (Table 2), and both radiocarbon and U-Th dating of tubes (Table 1), indicate that tube formation and fluid seepage were contemporaneous at Fossil Hill during the period 20–25 cal ka BP, while dating of shells additionally suggests that the larger chemosynthetic bivalve species, Phreagena soyoae, was also living at the site during this time (Table 1). Still images were later extracted from the video footage, and loaded into PhotoScan Pro (v. 1.1.6, Agisoft LLC) to build the mosaic. Lett. The crown, used … 102, 2300–2312. All of the Fossil Hill serpulid tubes analyzed through radiocarbon dating have maximum ages of 23–24 cal ka BP (Table 1) while U-Th dating suggests some tubes are over 16–30 ka old (Table 2), demonstrating that this accumulation is remarkably recent in origin and that the species responsible for the accumulation may still be extant. Members of this family are also notable for their gregarious behavior, amassing to form vast reefs by using the tubes of conspecifics as settlement substrate (ten Hove and van den Hurk, 1993). Geol.

Nat. *Correspondence: Magdalena N. Georgieva,;, Front. Assoc. An intriguing question presented by the above scenario is why serpulids, rather than symbiont-bearing chemosynthetic fauna, would have dominated Fossil Hill during a possible period of intense methane seepage during the LGM. Radiocarbon (14C) dates of Fossil Hill bivalve shells and serpulid tubes. (2017). Laminatubus alvini gen. et sp. The subset of Fossil Hill U-Th dates that also predate the LGM could suggest that factors other than nutritional benefits from seepage productivity may have been responsible for serpulid reef growth. doi: 10.1029/2010GC003318, Barbieri, R., Ori, G. G., and Cavalazzi, B. Based on this approach we estimate the age of tube-associated authigenic carbonates recovered during dives DR626-630 to be around 17–30 ka (Table 2). 390, 35–41. An old specimen from a famous old locality. The locations of recent fault offsets (red arrows), sediment drape covering or lapping onto the mound (orange arrows), and artifacts associated with a multiple reflection off the sea surface (gray arrows) are shown. This auction is for the fossilized marine worm, Esconites zelus. (2015). Fossil Hill is positioned on top of a ridge-like tectonic feature (Figure 2), and appears to have formed on the eroded crest of this ridge where accumulating sediment was thin or absent. Estonian Acad. Tubes within rock samples also exhibited altering orientations, at times being mostly aligned in parallel (Figures 4D,F).
