“…Size preference by the Phycosiphon/Chondrites-producers related with their feeding strategies.-Burrows and feces of marine benthic animals are usually coated by mucus or mucus membrane (Bromley 1996), which contains abundant reactive organic matter (Lalonde et al 2010;Petrash et al 2011). Therefore, it is reasonable that Phymatoderma pellets, which have been interpreted as fecal pellets excreted by a surface deposit-feeding producer (Miller and Aalto 1998;Miller and Vokes 1998;Izumi 2012), were attractive for other benthos; thus Phymatoderma reworked by other ichnogenera such as Chondrites and Phycosiphon were recognized (Fig.…”

Fine-grained sandstones and siltstones of Late Cretaceous to Eocene age in Antarctica and Tierra del Fuego yield an association of well-known shallow-marine trace fossils. Among them stick out complex spreite burrows, which are formally described asEuflabellan. igen. and subdivided into five ichnospecies with different burrowing programs and occurrences. As shown by concentrations of diatoms, radiolarians, foraminifers, and calcispheres in particular backfill lamellae, the unknown trace makers lived on fresh detritus from the surface as well as the burrowed sediment. In some ichnospecies, vertical sections show that the spreite is three-dimensionally meandering in upward direction and that upper laminae tend to rework the upper backfill of the folds underneath. This could mean a second harvest, after cultivated bacteria had time to ferment refractory sediment components, which the metazoan trace maker had been unable to digest before.

“…Moreover, boring organisms excrete mucus to garden their boring holes by incorporating organic matter into the walls Koller et al, 2006), the mucus layers lined on the inner side of boring walls usually are as thick as 5 μm and are composed of protein-rich mucopolysaccharide (Petrash et al, 2011). The mucus layer may friendly help constructing a favorable site for the accumulation of metallic ions through organo-metallic complexation or chelation at 25 suitable Eh, pH and redox conditions (Lalonde et al, 2010;Banerjee, 2000).…”

“…Burrowing and boring organisms play a critical role in sediment evolution because it enhances interactions between 10 sediments, the interstitial waters and overlying water by changing the geochemical gradients in the sediment, restructuring bacterial communities, and influencing the physical characteristics of the sediment (Lohrer et al, 2004;Meysman et al, 2006;Barsanti et al, 2011;Lalonde et al, 2010). Although organismic burrowing and boring has already been recognized as a factor that may influence CaCO3 sediment profiles (Emerson and Bender, 1981;Aller, 1982;Emerson et al, 1985;Green et al, 1992), and may promote carbonate dissolution in coastal sediments (Gerino et al, 1998), little is known about the 15 relationship between boring and bioturbation in semi-lithified and lithified carbonate rocks in deep sea settings.…”

Abstract. Deep-sea carbonates represent an important type of sedimentary rock due to their effect on the composition of upper oceanic crust and their contribution to deep-sea geochemical cycles. However, the lithification of deep-sea carbonates at the seafloor has remained a mystery for many years. A large lithified carbonate area, characterized by thriving benthic faunas and tremendous amount of endolithic borings, was discovered in 2008, blanketed on the seafloor of ultraslow 10 spreading Southwest Indian Ridge (SWIR). Macrofaunal inhabitants including echinoids, polychaetes, gastropods as well as crustaceans, are abundant in the sample. The most readily apparent feature of the sample is the localized enhancement of density around the borings. The boring features of these carbonate rocks and factors that may enhance deep-sea carbonate lithification are reported. We suggest that active boring may trigger the dissolution of the original calcite and thus accelerate deep-sea carbonate lithification on mid-ocean ridges. Our study reports an unfamiliar phenomenon of non-burial carbonate 15 lithification and interested by the observation that it is often associated with boring feature. These carbonate rocks may provide a novel mechanism for deep-sea carbonate lithification at the deep-sea seafloor and also illuminate the geological and biological importance of deep-sea carbonate rocks on mid-ocean ridges.

“…The advantages of a surrogate approach include easier protocols and increased experiment-design flexibility to model the geochemical effects of burrow linings. In this contribution we demonstrate that the commercially available Type III porcine gastric mucin (PGM) represents a strong candidate to act as such an experimental surrogate as its reactive site identities, available site concentrations, and Cd adsorption behavior strongly resemble that of mucous secretions secreted by terebellid polychaetes under laboratory conditions (Lalonde et al, 2010).…”

“…Polyelectrolyte functional groups, comprising the macromolecular structure of mucin, deprotonate under typical pH conditions of marine pore water systems, conferring a net negative charge to mucous gels that allow them to react with dissolved cations (Aller, 1983;Marriot and Gregory, 1990;Bansil and Turner, 2006). Lalonde et al (2010) indicated that mucous secretions of marine worms are unusually reactive, possessing a high density (per unit mass) of organic functional groups with the potential to exert control over element partitioning between overlying seawater and bioturbated sediments.…”

Many infaunal marine invertebrates produce mucous excretions, composed primarily of the glycoprotein mucin, that play important roles in burrow stabilization. As with other biopolymers, the ionization of mucin provides highly reactive organic ligands that enable the sorption of metal cations from seawater. Owing to the difficulties in its isolation, however, the specific role of mucin in the adsorptive properties of animal secretions in marine environments is poorly understood. Here we apply a surface complexation approach to model proton and Cd adsorption behavior of partially purified Type III porcine gastric mucin (PGM), a commercially available analog to natural infaunal mucus. FTIR, proton and cadmium adsorption experiments indicate that Type III PGM mimics the acid-base and metal complexation behavior of natural mucous gels excreted by terebellid polychaete worms. At marine pH, nearly two-thirds of the total ligands in mucin-type glycoproteins are deprotonated and thus available to participate in metal cation adsorption reactions. Importantly, the concentration of available organic ligands in mucin exceeds (by up to 5 times) that of a variety of other metal-reactive organic compounds comprising the organic fraction of marine sediments. A substantial fraction of the dissolved organic matter in the bioturbated zone of marine sediments occurs in the form of mucin-associated glycoproteins; the availability of such organic materials may strongly influence the distribution of cations at the burrow margin.
