A late Paleocene fauna from shallow-water Chemosynthesis-based ecosystems, Spitsbergen, Svalbard
Institute of Paleobiology PAS, 2019Co-Authors: Krzysztof Hryniewicz, Kazutaka Amano, Maria Aleksandra Bitner, Jonas Hagström, Steffen Kiel, Adiël A. Klompmaker, Thomas Mörs, Cristina M. Robins, Andrzej KaimAbstract:We present a systematic study of late Paleocene macrofauna from methane seep carbonates and associated driftwood in the shallow marine Basilika Formation, Spitsbergen, Svalbard. The fauna is composed of 22 taxa, comprising one brachiopod, 14 bivalves, three gastropods, three crustaceans, and one bony fish. The reported fish remains are among the first vertebrate body fossils from the Paleogene of Spitsbergen. One genus is new: the munidid decapod Valamunida Klompmaker and Robins gen. nov. Four new species are described: the terebratulide brachiopod Neoliothyrina nakremi Bitner sp. nov., the protobranch bivalve Yoldiella spitsbergensis Amano sp. nov., the xylophagain bivalve Xylophagella littlei Hryniewicz sp. nov., and the munidid decapod Valamunida haeggi Klompmaker and Robins gen. et sp. nov. New combinations are provided for the mytilid bivalve Inoperna plenicostata, the thyasirid bivalve Rhacothyas spitzbergensis, the ampullinid gastropod Globularia isfjordensis, and the munidid decapod Protomunida spitzbergica. Thirteen taxa are left in open nomenclature. The fauna contains a few last occurrences of Cretaceous survivors into the Paleocene, as well as first occurrences of Cenozoic taxa. It is composed of chemosymbiotic thyasirid bivalves and background species common in the northern Atlantic and Arctic during the Paleocene. Our results provide no evidence for a Paleocene origin of vesicomyid and bathymodiolin bivalves typical for Eocene and younger seep environments; instead, the Paleo cene seeps of the Basilika Formation are more similar to their Late Cretaceous equi valents rich in thyasirids

new bivalves from a middle devonian methane seep in morocco the oldest record of repetitive shell morphologies among some seep bivalve molluscs
Journal of Systematic Palaeontology, 2017Co-Authors: Krzysztof Hryniewicz, Michal Jakubowicz, Zdzislaw Belka, Jolanta Dopieralska, Andrzej KaimAbstract:A fauna of bivalve molluscs is described from methane seep carbonates of the Middle Devonian (c. 390 Ma) Hollard Mound in the eastern Anti-Atlas, Morocco. We describe a new modiomorphid genus Ataviaconcha gen. nov. with the type species Ataviaconcha wendti sp. nov. This is a very large, semi-infaunal species occurring in large colonies similar to those formed by Recent chemosymbiotic cold-seep and hydrothermal vent bivalves. It is the second modiomorphid bivalve known from Palaeozoic Chemosynthesis-based ecosystems, after the roughly coeval Sibaya ivanovi Little, Maslennikov, Morris & Gubanov, 1999, from the Sibay hydrothermal vent deposit in the Ural Mountains, Russia. The second and much less numerous bivalve species described in this paper is the solemyid Dystactella? eisenmanni sp. nov., belonging to a genus known also from Ordovician to Devonian marine environments distinct from cold seeps and hydrothermal vents. As with other fossil and Recent solemyids, it was an infaunal burrower, most likely livi...

gastropods from late cretaceous omagari and yasukawa hydrocarbon seep deposits in the nakagawa area hokkaido japan
Acta Palaeontologica Polonica, 2009Co-Authors: Andrzej Kaim, Robert G Jenkins, Yoshinori HikidaAbstract:Sixteen gastropod species from two Campanian (Upper Cretaceous) hydrocarbon seep localities in Hokkaido, Japan are described. Seven species are new: the acmaeid limpet Serradonta omagariensis; three turbinids: Homalopoma abeshinaiensis, Cantrainea yasukawensis, and C. omagariensis; the trochid Margarites sasakii; the seguenzioid Cataegis nakagawensis; and the provannid Provanna nakagawensis. The most common species in the investigated localities are acmaeid limpets (S. omagariensis), tiny turbinids (H. abeshinaiensis, C. yasukawensis, C. omagariensis), and provannids/hokkaidoconchids (P. nakagawensis and Hokkaidoconcha hikidai). The Upper Cretaceous associations described here do not resemble Lower Cretaceous associations known from other regions but are composed of species similar to gastropods from Recent hydrocarbon seeps and hydrothermal vents in the Northwestern Pacific. This strongly suggest that this region possesses a regional pool of gastropods in Chemosynthesis-based communities at least since L...

Chemosynthesis based associations on cretaceous plesiosaurid carcasses
Acta Palaeontologica Polonica, 2008Co-Authors: Andrzej Kaim, Robert G Jenkins, Yoshitsugu Kobayashi, Hiroki Echizenya, Kazushige TanabeAbstract:The objective of this report is to document first Mesozoic occurrences of Chemosynthesis-based communities developed on large marine reptile carcasses. Micro-grazing provannid gastropods (typical of chemosynthetic communities) are associated with plesiosaurid skeletons in the Upper Cretaceous deposits of Hokkaido, northern Japan. The cancellous bones of the examined plesiosaurid bones contain a ubiquity of iron sulfides within the bone trabeculae, which provides evidence of anaerobic sulfate reduction of the bone lipids. We also report numerous microborings in the bone trabeculae, which might result from the activity of sulfur-oxidizing bacteria. This finding addresses the hotly debated problem of the emergence and radiation of whale bone faunas. We postulate that vertebrate bone environments in the Northwest Pacific region were settled repeatedly by animals from a regional pool of Chemosynthesis-based communities that flourished in the methane seeps and/or hot vents that were present during the Late Cret...

antiquity of the substrate choice among acmaeid limpets from late cretaceous Chemosynthesis based communities
Acta Palaeontologica Polonica, 2007Co-Authors: Robert G Jenkins, Andrzej Kaim, Yoshinori HikidaAbstract:Two Campanian methane seep sites in the Nakagawa area of Hokkaido (northern Japan) yield fossils of the limpet genera Serradonta and Bathyacmaea that appear to have had the same substrate preference as do their modern counterparts. Serradonta cf. vestimentifericola was a species having an elongated and strongly compressed shell adapted to living on vestimentiferan tubes, like its modern relatives. Bathyacmaea cf. subnipponica was an acmaeid with a relatively elon− gated shell but with a more rounded aperture than Serradonta and thus apparently attached to small hard objects other than worm tubes. One Bathyacmaea specimen was found attached in situ to an ataphrid gastropod shell. The restricted present−day distribution of Serradonta possibly reflects its spreading route exclusively through the hot vent and cold seep communities settled by vestimentiferans.

the stable isotope fingerprint of chemosymbiosis in the shell organic matrix of seep dwelling bivalves
Chemical Geology, 2018Co-Authors: Dong Feng, Steffen Kiel, Jorn Peckmann, Jian-wen Qiu, Jun Tao, Qianyong Liang, Robert S Carney, Yongbo Peng, Duofu ChenAbstract:Abstract Chemosymbiotic bivalves harboring endosymbiotic, chemotrophic bacteria have been investigated from a variety of hydrocarbon seeps worldwide. It has been shown that carbon, nitrogen, and sulfur isotopic compositions of the animal soft body parts are excellent indicators for evaluating energy transfer and food sources for the respective deep-sea habitats. However, recognition of chemosymbiosis has proven to be difficult for bivalves that dwelled at ancient seeps due to the lack of soft tissue. Here, we investigated δ13C, δ15N, and δ34S signatures of the tissue (mantle) and the shell organic matrix (SOM) of the same specimens of three bathymodiolin mussel species with different chemotrophic symbionts (methanotrophs in Bathymodiolus platifrons and B. childressi and thiotrophs in B. aduloides) and one vesicomyid clam (Calyptogena sp.) from a variety of hydrocarbon seeps from the South China Sea and the Gulf of Mexico. The data obtained demonstrate that all seep bivalves regardless of species or locations reveal overall small differences in δ13C (≤+4‰), δ15N (≤+1‰), and δ34S (≤+5‰) values between SOM and mantle (∆SOM-mantle) of the specimens. Relatively larger ∆SOM-mantle for δ13C values (as high as +10‰) in B. platifrons and larger ∆SOM-mantle for δ34S values (up to 16‰) in B. aduloides and Calyptogena sp. might be due to different symbionts in their gills. Since SOM can be extracted from fossil bivalve shells, the proxy can be used as a fingerprint of Chemosynthesis-based food chains, although its utility will depend on the quality of preservation of the shell organic matter. Despite this uncertainty, the new proxy has great potential to reconstruct energy flow through different types of Chemosynthesis-based ecosystems.

Chemosymbiotic bivalves from the late Pliocene Stirone River hydrocarbon seep complex in northern Italy
Institute of Paleobiology PAS, 2018Co-Authors: Steffen Kiel, Marco TavianiAbstract:Seven species of chemosymbiotic bivalves are described from the late Pliocene Stirone River hydrocarbon seep complex in northern Italy, including one new species and two in open nomenclature. The known species are the solemyid Acharax doderleini, the lucinids Lucinoma persolida and Megaxinus ellipticus, and the vesicomyid Isorropodon aff. perplexum; in open nomenclature we report two lucinids, including the largest species of Lucinoma known from the Italian Pliocene to date, and a strongly inflated, large Anodontia sp. The most abundant species at the Stirone seep complex is the lucinid Megaxinus stironensis sp. nov. This Pliocene seep fauna differs from that of the well-known Miocene “Calcari a Lucina” seep deposits by lacking large bathymodiolin mussels and vesicomyid clams; instead, the dominance of the lucinid Megaxinus stironensis gives this fauna a unique character. We speculate that at the Stirone seep complex, Megaxinus had occupied the ecological niche that Meganodontia occupied at the Miocene “Calcari a Lucina” seep sites in the Mediterranean basin, and that the dominance of Megaxinus could be a wide-spread feature of Pliocene Chemosynthesis-based ecosystems in Mediterranean Pliocene

establishing criteria to distinguish oil seep from methane seep carbonates
Geology, 2016Co-Authors: Daniel Smrzka, Gerhard Bohrmann, Jennifer Zwicker, Andreas Klugel, Patrick Monien, Wolfgang Bach, Jorn PeckmannAbstract:Hydrocarbon seeps harbor copious Chemosynthesis-dependent life, the traces of which are preserved in the fossil record within authigenic carbonates. These environments are mostly characterized by seepage of methane-rich fluids, yet numerous crude oil–dominated seeps have been discovered in recent years. Oil seepage has a profound influence on the local fauna, but recognizing such seeps in the rock record remains elusive. This study presents new geochemical data that will allow for a more confident identification of ancient oil-seep deposits. Geochemical data from modern and ancient seep limestones reveal that oil-dominated seep carbonates are enriched in rare earth elements and uranium compared to their methane-dominated counterparts. These trace element patterns have the potential to serve as a basis for an improved understanding of the adaptation of chemosynthetic life to oil seepage, and to better constrain the marine carbon cycle in the geologic past.

psychromonas kaikoae sp nov a novel piezophilic bacterium from the deepest cold seep sediments in the japan trench
International Journal of Systematic and Evolutionary Microbiology, 2002Co-Authors: Yuichi Nogi, Chiaki Kato, Koki HorikoshiAbstract:Two strains of obligately piezophilic bacteria were isolated from sediment collected from the deepest cold-seep environment with Chemosynthesis-based animal communities within the Japan Trench, at a depth of 7434 m. The isolated strains, JT7301 and JT7304 T , were closely affiliated with members of the genus Psychromonas on the basis of 16S rDNA sequence analysis. Hybridization values for DNA-DNA relatedness between these strains and the Psychromonas antarctica reference strain were significantly lower than that accepted as the phylogenetic definition of a species. The optimal temperature and pressure for growth of the isolates were 10 °C and 50 MPa and they produced both eicosapentaenoic acid (C20:5ω3) and docosahexaenoic acid (C22:6) in the membrane layer. Based on the taxonomic differences observed, the isolated strains appear to represent a novel obligately piezophilic Psychromonas species. The name Psychromonas kaikoae sp. nov. (type strain JT7304 T = JCM 11054 T = ATCC BAA-363 T ) is proposed. This is the first proposed obligately piezophilic species of the genus Psychromonas.
