However, the dwelling tubes that many annelids create are often more robust structures that have a greater likelihood of becoming preserved as fossils (Ippolitov et al. Excl. Because of their hard mineral tubes, these animals have the best fossil record of all worms. Resolved near vestimentiferans by all analyses. NHMUK VF71, single tube fragment. Scale bars: A–C = 10 mm; D, F, G = 1 mm; E = 500 µm. Fossils (grey crosses): 1. Pyritic tubes 0.3–7.0 mm in diameter, non-tapering, sometimes gently curved and with smooth walls (Fig. 1999; Buschmann & Maslennikov 2006). 1999c). 5 mm. 1989 serpulid worm tubes Beauchamp, Harrison, Nassichuk, Krouse, & Eliuk: 54, fig.

PCA was performed using PAST (Hammer et al. Scale bars: A = 20 mm; B = 2 mm; C = 1 mm; D, E = 200 µm. Mississippian Meramecian Series Warsaw Formation St. Louis County, Missouri. 8B, D). OMG03-4a, pinkish calcite with many worm tubes with brown walls (Fig. 18A–C). Tubes from modern annelid families for detailed study and comparison with fossil material (Supplementary File 1, Table S3) were chosen on the basis of two main criteria: (1) those that occur within modern vents and seep environments, and (2) those for which difficulties in discrimination in the fossil record of vents and seeps have been noted. ‘Wilbur Springs tubes’, WS-45, Hauterivian, California, USA. The tube surface between adjacent collars appears smooth and unornamented (Fig. The tubes were clearly organic, due to preserved wall tears that reveal a fibrous nature. The diameter range of the tubes, as well as the hard, organic, mostly thick and multi-layered nature of the tube walls, are typical of most vestimentiferans. Mudstone of Middle Ezo Group, Cenomanian, Cretaceous (Majima et al. 6A–C) and thin section (Fig. 2013); however, these tubes are more irregular along their length, while Conotubus fossils do not possess the mesh-fibre pattern preserved on T. serriformis tubes. When homoplastic characters are down-weighted less (k = 4; Fig. 2A–C and E–G).In addition, seven Promicroceras with fragments of worm tubes attached were collected that are too poorly preserved for analysis.Table 2 summarizes the available evidence for the site of initial attachment. ‘Murdock Creek tubes’, WA-MC LACMIP loc. 1999c; Buschmann & Maslennikov 2006). 9F–I) that is very thick and well consolidated in some of the tubes (Fig. 3A), and appearing to have been originally rigid as they demonstrate clean fractures (Fig. C, fossil tube from West Fork Satsop River, Washington State, USA (WFSR 1A), detail of transverse section. (2020, August 27). The degree to which homoplastic characters are down-weighted during the analysis is determined by the concavity constant k, which is set to 3 by default in TNT. Characters identified from these investigations were used to explore for the first time the systematics of ancient vent and seep tubes within a cladistic framework. A, consensus of 271 most parsimonious trees (best score = 15.387, consistency index = 0.195, retention index = 0.264); B, consensus of 60 most parsimonious trees (best score = 13.568, consistency index = 0.232, retention index = 0.569). sediment grains), and tubes comprised purely of an organic secretion.

NHMUK VF78, 80, 84, 89, 97, NHMUK OR 6468a, 6468b, very large tubes mostly preserved singly. 5d. 12-RK, small and larger diameter tubes, mostly in the same orientation. 2008b; Kaim & Kelly 2009). As the tubes are fairly round in thin section, it is inferred that they were originally rigid (Fig. Search for: Search. However, the tubes are on the whole difficult to interpret due to the inability to assess tube ornamentation and the poor state of preservation of the tube walls. These have shown the occupation of vents and seeps by animal life to be ancient, dating back to the Silurian period, approximately 443–419 Ma (Little et al. Analyses were performed using implied character weighting, with the concavity constant set as default (k = 3; A), and also set to downweight homoplastic characters less (k = 4; B). 2006; Levin & Mendoza 2007; Kupriyanova et al. (2014). ; Buschmann & Maslennikov: 147, figs 7, 8. Some tube sections show well-consolidated lamination that is many layers thick (Fig. 2014), even when molecular data were included (Supplementary File 1, Figs S1, S2), likely reflects the more limited sampling of annelid taxa within our analyses. Serpula spp.). Fossil Worm Tubes, 7000 years old, Ford Creek, Washington, USA. Resolved among vestimentiferans by all analyses. D, branched tube of Phyllochaetopterus claparedii (Chaetopteridae). 17A, B) (Little et al. Murdock Creek, Clallam County, Washington State, USA (∼48°9′N, 123°52′W). They are 2.0–10.0 mm in diameter, more or less straight, and have smooth walls. The paper is titled "A Cambrian crown annelid reconciles phylogenomics and the fossil record." 1E, G, H), with delamination occurring between some layers (Fig. Clusters of fossil serpulid worm tubes, like these Rotularia from the British Eocene, are common fossils in many Mesozoic and Cenozoic marine rocks The Museum’s collection of fossil annelids is both geologically and geographically diverse. 2e. 14C). 2013).

Scale bars: A = 10 mm; B = 2 mm; C = 5 mm; D, E = 300 µm; F = 100 µm; G = 200 µm. Highly frayed edges can be seen, suggesting that tubes were originally organic and fibrous (Fig. The surprising fossil discoveries of Danise & Higgs (2015) and the reinterpretations presented here emphasize that the evolutionary history of this remarkable family warrants further investigation, and we therefore urge that an earlier origin for the main tube-building vent and seep annelid lineage, the vestimentiferans, be considered and incorporated into a much-needed new molecular age estimation for Siboglinidae. Fossil Serpulid Tubes. Donated by J. L. Goedert. Tube walls are uncompressed, suggesting that they may have originally been rigid, and are multi-layered (Fig. Tubes do not have collars, and instead possess fine transverse and longitudinal wrinkles on their surfaces, with the transverse wrinkles often being more pronounced and fairly regular (Fig. NRC C-453961 PPL, C-453989 PPL, tubes observed in thin section. The morphology of Omagari tube clumps very closely resembles a clump of the roots of the seep vestimentiferan Lamellibrachia luymesi (Fig. Marine Ecology - Biotic and Abiotic Interactions. Identification of fossil worm tubes from .... Tube similarities and phylogenetic relationships, Organic constituents of modern tubes and their preservation, https://doi.org/10.1080/14772019.2017.1412362. The above methods, however, need to be applied with greater caution for very ancient tube fossils (such as those from the Palaeozoic), as the identity of these fossils will largely be evaluated with respect to modern tubes from which they are very distant in time. 23B); therefore, this affinity is only tentatively suggested. The tubes appear to have been originally flexible as they often show folding and creases (Fig. Tube walls are thick and multi-layered, and at times delaminated (Fig. They've focused their excavations in … Kinousa 2023, Memi 2021, sinuous worm tubes that appear attached to a surface, several tubes often occurring together. The analysis was based on the 48 mostly morphological tube characters and was performed using implied character weighting (k = 3). ‘Rocky Knob tubes', Middle Miocene, New Zealand. Figure 2. First report of the ichnogenus Phymatoderma from the Hayama Group (Miocene, Japan): Paleobiological and paleoecological implications. 1989; Beauchamp & Savard 1992). 2004). Siboglinid, chaetopterid and serpulid tubes may all possess collars and occur at vents, while siboglinid and serpulid tubes may both be highly spiralling. Fossil Worm Tubes - Oxfordshire. Selected modern tubes were initially photographed, after which lengths of approximately 10 mm were cut from a subset of these for further analyses. E, detail of tube wall in transverse section showing a thick calcareous band occurring on the outside of the brown tube wall layers. Figure 21. The tubes appear to have originally been rigid as walls are generally not compressed, both in hand specimen (Fig. These were performed using the parsimony program TNT v. 1.1 (Goloboff et al. High resolution analysis revealed the localization of zinc‐sulfur (sphalerite, ZnS) on the tubes, while iron‐sulfur (pyrite, FeS2) was localized at the center of the tubes. 1A, B). The cladistic analysis of modern tubes only (Fig. Secondly, we analyse these data within a more objective, modern cladistic framework. B, NHMUK VF97, cast of tube exhibiting fold. 5.1e–i. We therefore suggest that vestimentiferans are the most likely builders of these tubes, but this assignment is tentative due to the poor resolution of these tubes in the cladistic analysis. Agglutinated tubes occur in families such as Sabellidae and Terebellidae, or only in a subset of members of a family, e.g. In thin section, the tube walls are preserved as brown-yellow rims showing evidence of multi-layering and mineral growth between tube layers (delamination) (Fig. I, clump of the roots of the seep vestimentiferan Lamellibrachia luymesi (donated by C. Fisher). F, Phyllochaetopterus polus (Chaetopteridae) tubes bearing short collars and wrinkled-fabric ornamentation. 2D). 4A, B). 3099067 Although outer tube wall ornamentation could not be assessed, the at times thick walls that these tubes possess, in combination with the morphology of the tube cluster, suggest that they may represent the fossilized root portions of vestimentiferan tubes (cf. RK-5, block of many large-diameter tubes, mostly in the same orientation. Use the link below to share a full-text version of this article with your friends and colleagues. 2013). 2D, E). To advance the understanding of the evolutionary history of deep-sea hydrothermal vents and cold seep communities, this study aims to improve the taxonomy of the abundant but problematic fossil annelid tubes from Phanerozoic vents and seeps. A, smooth-walled, tapering tube in hand specimen. The above study also highlights that better morphological assessment of fossils is needed to clarify the evolutionary ages of vent and seep fauna. Such characters include longitudinal wavy ridges, tube collars (or flanges) and multi-layered tube walls, as well as the size and mass occurrence of tubes. Fig. In this study, we make a detailed chemical (Fourier-transform infrared spectroscopy and pyrolysis gas-chromatography mass-spectrometry) and morphological assessment of modern annelid tubes from six families, and fossil tubes (seven tube types from the Cenozoic, 12 Mesozoic and four Palaeozoic) from hydrothermal vent and cold seep environments. Gaojishania cyclus tubes bear small annulations resembling collars (Cai et al. 2014; Parry et al. Carbonate tube sections measuring 2.9–5.7 mm in diameter, all fairly straight, and not attached to other tubes. 2008; Saether 2011). Geo-Biological Landscapes. Both of these lineages build small-diameter (mostly less than 1 mm) tubes that are often long compared to their diameter, with frenulate tubes generally exhibiting greater morphological diversity. The abundance of these tubes at this ancient seep, large diameter range, generally smooth organic tube walls, and the thick, neatly multi-layered tube wall appearance in some of the specimens do suggest a vestimentiferan affinity. 1999). 2005). 10A, B). A–C, ‘Troodos collared tubes’; A, B, Kambia 4061 and Memi 212b2, respectively, sinuous worm tubes with collars; C, Kambia 401b, worm tube with collar attached at an oblique angle. However, the lack of correspondence of deeper annelid branches within our analyses to existing annelid molecular phylogenies (e.g. the anterior, middle and posterior portions of frenulate tubes). A–C, WA-CR LACMIP 16957; A, large-diameter tubes in hand specimen; B, smooth small-diameter tubes; C, small-diameter tube with longitudinal wrinkles. While there has been some confusion as to whether chaetopterid tubes contain chitin (Barnes 1964; Ippolitov et al. 2013 tubeworms Williscroft: 20, fig. Royal Ontario Museum. Ural Mountains, Russia (51°24.43′N, 57°41.63′E). A, B, WFSR-3B and WFSR JLG 459C, respectively, tubes in hand specimen showing wavy nature and smooth tube walls. Fossil tubes from two localities (Bear River, Wilbur Springs) were also removed from the character matrix prior to any subsequent analyses. 20Z) appeared unique to this group, and are therefore a key identifying character for this lineage, whereas segments or wrinkled fabric-type textures that were observed in frenulate tubes can also occur in the tubes made by other families. 1999 Yamankasia rifeia Shpanskaya, Maslennikov & Little: 225, plate 3, figs 1–6. Further details of the py-GC-MS methods used can be found in Supplementary File 1, Methods Supplement 2. Fossil Worm Tubes at Winspit. O, detail of the wall of an Alvinella spp. 23B), they cluster near serpulids within the PCA plot (Fig. 2014). Some of the tube sections also show signs of compression and/or shrinkage. Whether or not the tubes taper is unknown, and details of wall ornamentation could not be assessed. ‘Cold Fork Cottonwood Creek tubes’, Hauterivian, California, USA. 23B) due to the coarse transverse wrinkles which they both exhibit. FTIR analyses were performed using a Nicolet Nexus FTIR bench unit (Thermo Scientific, Waltham, MA, USA) at Imperial College, London (ICL) in attenuated total reflectance mode. Do not clearly group within a modern annelid family in cladistic analyses, although one tube resembles those of siboglinids in section. W, X, E. southwardae tube; W, detail of the anterior tube wall in transverse section; X, transverse section of the posterior tube wall. Carbonate tubes mostly straight and exhibiting a wide range of diameters, from 1.0 to 7.9 mm, preserved in clusters mostly of similar-sized tubes (Fig. MICHELLE STARR. Langton Herring. These tubes were resolved among siboglinids only within the cladistic analysis that allowed more homoplasy (Fig. The latter composition most notably occurs in the tubes of siboglinids (Brunet & Carlisle 1958; Shillito et al. This specimen was found in Tarrant County, Texas. Figure 1. Provided by S. E. Grasby. The tube wall ornamentation of fine closely spaced transverse wrinkles is also seen in many members of this family (e.g. Svalbard 2007-03, long tube with yellowish wall. 1984), multiple fossil analogues of these communities were also described. Selected tube characters were used to create a character matrix (Supplementary File 1, Table S4) in which morphological and compositional aspects of modern and fossil tubes were scored using findings from this study as well as the existing literature. D, detail of framboidal pyrite preserving tube walls. Morphology of tubes made by annelid lineages occurring at modern hydrothermal vents and cold seeps (see Supplementary Table S3 for details). 13C–E). However, these identifications have been challenged as the morphological characters used to make the diagnoses are not unique to the vestimentiferans, being also present in other annelid families as well as non-annelid fossil taxa (Kiel & Dando 2009). 2014) and Sinotubulites (Cai et al. E, RK-15B-6B, tube in transverse section showing preserved torn fibres. We therefore tentatively suggest that the Omagari tubes may be vestimentiferan tube roots. 1999a vestimentiferan worm tubes Little, Cann, Herrington, & Morisseau: 1028, fig.

Seep carbonate lenses in serpentenites and siltstone turbidites, Great Valley Group, Hauterivian, Cretaceous (Campbell 1995; Campbell et al. Worm tubes were found in siltstone and limestone, and formed network‐like assemblages. 2008), but identification based on their morphologies has proved difficult. Sassenfjorden area, Svalbard. 6E), and fluorescence during CLSM analysis of the tube walls further suggests that the tubes were originally organic (Fig. Abstract Fossil worm tubes were collected from the Hayama Group, Miura Peninsula, Japan, together with abundant fossils of Calyptogena‐Acharax clams. Several modern organic tubes covering a range of annelid families were initially analysed using Fourier transform infrared spectroscopy (FTIR). Preserved tears of the tube wall reveal an originally fibrous nature (Fig. Small carbonate tubes, 1.1–2.4 mm in diameter, fairly straight, non-branching and non-agglutinated (Fig. Sibay massive sulphide deposit, southern Ural Mountains, Russia (52°41.66′N, 58°38.15′E). ‘Bear River tubes’, LACMIP 5802 BRB-1, late Eocene, Washington State, USA. Some of the tubes have smooth walls (Fig. Possible worm tube 3 is the meandering impression on the venter (B) to the left of ?3. D, detail of tube wall where a preserved tear occurs, revealing fibre endings (grey arrow). 23 JANUARY 2018 . A, CFC-G, tubes in hand specimen, walls largely obscured by rock matrix. These tubes are not preserved well enough to be assigned to a particular animal group, and were not included in cladistic and cluster analyses as so few characters could be coded. Some of the tubes appear to have originally been flexible (Fig. A–F, H, I, ‘Figueroa tubes’, Pliensbachian, California, USA; A–C, tubes in hand specimen; A, FFC-12, straight, tapering tube with fine longitudinal wrinkles; B, FFC-00-21, tube fragment bearing longitudinal wrinkles and collars; C, FFC-18B, tube with longitudinal wrinkles and a fine, obliquely positioned collar; D, FFC-18, longitudinal section of tube exhibiting long, flaring collars; E, FFC-12, scanning electron microscopy (SEM) image showing details of tube wall ornamentation; F, FFC-12, greater detail of same tube; H, FFC-19, detail of tube transverse section showing preservation of tube walls; I, FFC-19, detail of tube wall in transverse section. Upper Waiau River, northern Hawke's Bay area, east coast of North Island, New Zealand (∼38°13′S, 178°5′E). Tube wall surfaces exhibit numerous fine, parallel transverse wrinkles (Fig. However, the taxonomic affinities of many tube fossils from vents and seeps are contentious, or have remained largely undetermined due to difficulties in identification. Results of principal coordinate, phylogenetic and tube compositional analyses are subsequently presented. These were found in the Lower Kimmeridgian clay of Abingdon, Oxfordshire, UK. 49.6 MB (777.5 KB compressed) 5100 x 3400 pixels. The above analyses also confirmed the presence of chitin in Sclerolinum, as well as the root portions of two vestimentiferan tubes (Supplementary File 1, Table S7), and the inclusion of tube organic constituents within the tube character matrix also helped to resolve modern annelid families within cladistic analyses (Fig. At seeps, the original wall structure of an annelid tube may be preserved, allowing the determination of whether the tube was originally calcareous or organic; however, at vents this is more difficult as carbonate is rapidly dissolved and replaced. Collected by C. T. S. Little. Figure 18. Recently discovered borings of the bone-eating siboglinid worm Osedax in Late Cretaceous (∼100 million year old) plesiosaur and turtle bones (Danise & Higgs 2015), however, suggest that the older molecular age estimates for this family may be more accurate. Unresolved by cladistic analyses; tubes possibly resemble those of annelids more than those of other tubicolous animals. Worm tubes were found in siltstone and limestone, and formed network‐like assemblages. The utility of organic composition for tube identification does, however, appear to diminish during fossilization at vents and seeps. 11D, E). Cladistic analyses suggest possible chaetopterid affinity but outer tube morphology could not be assessed. Calcareous tubes are almost exclusively confined to the family Serpulidae, but single extant sabellid and cirratulid genera also produce calcareous tubes (Ippolitov et al. Screening of organic tubes for potential differences in composition using FTIR showed that tubes from the annelid families Siboglinidae and Alvinellidae had distinctly different FTIR spectra to Chaetopteridae tubes (Fig. 2011; Hryniewicz et al. 2015). 15A). Figure 5. Fossil tubes exhibiting the latter features would therefore be difficult to place, and for these reasons, we suggest that the Neoproterozoic fossil Sabellidites cambriensis may not have been made by a siboglinid, as suggested by Moczydłowska et al. Most of the fossils in the Reserve are found in the Delmar Formation at the bottom of Fossil log on the beach cliffs. These tubes were resolved only within the cladistic analysis that allowed for more homoplasy (Fig. The tubes of Alvinella spp. Based on tube morphology and occurrence within an ancient vent environment, many fossil vent and seep tubes have been assigned to the vestimentiferans (a subgroup of siboglinids comprising its larger members) (Little et al. Photographer. B, detail of tube wall showing smooth appearance. Preserved tears (Fig. Hydrothermal vents and cold seeps are remarkable sites in the deep sea, characterized by the ejection of chemically reduced fluids from the seafloor that fuel abundant life through the process of chemosynthesis (Van Dover 2000). 2008). 10E). 2008), for the following two data sets: (1) modern taxa, tube data only (43 taxa, 48 characters); and (2) modern and fossil taxa, tube data only (64 taxa, 48 characters). These tubes were suggested to have been made by vestimentiferans by Goedert et al. The tubes may also be transversely wrinkled (Buschmann & Maslennikov 2006).

These tubes were previously considered to have been made by serpulids (Beauchamp & Savard 1992; Williscroft 2013), but have more recently been interpreted as vestimentiferan worm tubes (Williscroft et al. 2014). We know of their existence from the impressions left behind in shale beds hundreds of millions of years old, once sediment at the bottom of a body of water. The faunal compositions of hydrothermal vents and cold seeps have undergone dynamic shifts over evolutionary time.
