“…Similar trace fossils are also known from internal shell surfaces of juvenile C. rubani specimens from Ukraine (Kiel and Peckmann 2008: fig. 6C), and the probable Caspiconcha specimen from the Omagari seep site, Japan (Hikida et al 2003: fig. 9−3).…”

“…Most occurrences of Caspiconcha are from Lower Cretaceous strata, indicating that this genus was characteristic of Early Cretaceous hydrocarbon seep environments. By the Late Cretaceous, however, Caspiconcha is found only in the Campanian Omagari hydrocarbon seep locality (Hikida et al 2003: fig. 9−3).…”

“…The seep−restricted rhynchonellide brachiopods became extinct at the end of Early Cretaceous (Kiel and Peckmann 2008), while Caspiconcha survived to the Late Cretaceous in Japan (Hikida et al 2003;Kiel et al 2010), although known so far from a single specimen at a single locality. After their extinction the niche for epifaunal and semi−infaunal organ− isms in hydrocarbon seeps was apparently unoccupied from the Late Cretaceous until the appearance of bathymodiolin bivalves in the Eocene (Fig.…”

Two new species ofRetiskenea? (Gastropoda: Neomphalidae) from Lower Cretaceous hydrocarbon-seep carbonates of northern California

Two new Mesozoic gastropod species, provisionally attributed to the minute (height < 5 mm) coiled neomphalid genus Retiskenea?, are described from three geographically isolated, Early Cretaceous, hydrocarbon seep-carbonate sites at Wilbur Springs, Rice Valley, and Cold Fork of Cottonwood Creek, northern California (USA). A fourth paleo-seep locality at Paskenta, of probable Upper Jurassic age, also yielded a single specimen of a morphologically similar microgastropod that may be a neomphalid with affinities to the Lower Cretaceous specimens described herein. the limestone lenses are ~2-260 m in length, ~1-5 m in diameter, and surrounded by forearc siliciclastics of bathyal turbidites or sedimentary serpentinites in the Upper Jurassic to Lower Cretaceous (Tithonian-Albian) Great Valley Group and its equivalents. the Lower Cretaceous microgastropods are tentatively placed in Retiskenea? based on similar shell characters: size, globose shape, inflated reticulate protoconch, number and distinct inflation of the body whorls, and fine, prosocline sculpture of the final body whorl. the fossils occur in carbonate microbialites that formed in seafloor sediments during archaeal anaerobic oxidation of methane in the zone of bacterial sulfate reduction, associated with H2S- and CH4-rich fluid seepage. the California Retiskenea? fossils commonly are found in gregarious clusters, or closely affiliated with thin worm tubes or, in one case, a larger gastropod.These Mesozoic records increase the total known species attributable to this cold-seep endemic genus from two to four. Its spatial and temporal distribution thus may have spanned ~9,000 km around the Pacific Rim from at least ~133 m.y. to the present in 10 subduction-related seep sites from California (possibly Upper Jurassic-Lower Cretaceous), Washington (middle Eocene-Upper Oligocene), and modern offshore Oregon, the eastern Aleutians, and the Japan Trench. If the generic placement of these microgastropod fossils is correct, the California records are the oldest-known occurrences of Retiskenea, consistent with an estimated minimum Mesozoic origin for the 'hot vent' Neomphalidae, as inferred from molecular analyses published on other living members of the family.
