Camptonectes sp. Bivalves from the latest Jurassic-earliest Cretaceous hydrocarbon seep carbonates from central Spitsbergen, Svalbard Hryniewicz, Krzysztof Little, Crispin T. S. Nakrem, Hans Arne Zootaxa 2014 2014-09-02 3859 1 1 66 Agassiz [151,378,1052,1078] Pectinidae Camptonectes Animalia Pectinoida 27 28 species undetermined  2011  Camptonectessp.—Hammer et al., fig. 7j.   Material examined.118 unnumbered specimens, all internal moulds with delaminated shells from seeps 1, 3, 4, 8 and 9. See Appendix 1 for the list of specimens.   Remarks.These specimens belong to the genus  Camptonectes, but the absence of external shell characters means they cannot be identified to species level. They most likely belong to the two species discussed above, but it is possible that some represent individuals of contemporary Jurassic and Cretaceous species, including  Camptonectes( Camptonectes) auritus( Schlotheim, 1813)and  Camptonectes( Camptochlamys) obscurus(J. Sowerby, 1818).
