Gigantidas Cosel & Marshall 2003
No full textGenus Gigantidas Cosel & Marshall, 2003 Type species. Gigantidas gladius Cosel & Marshall, 2003. Remarks. This genus was erected by Cosel & Marshall (2003) to include only the type species, with a second species, G. horikoshii Hashimoto & Yamane, 2005, added shortly afterwards from vent sites off Japan. A molecular analysis of bathymodioline mussels by Thubaut et al. (2013) moved the “ Bathymodiolus ” childressi clade into Gigantidas Cosel & Marshall, 2003, substantially increasing the number of extant species ascribed to this genus. Gigantidas coseli Saether, Little, Campbell, Marshall, Collins & Alfaro, 2010, from the Miocene of New Zealand, remains its only fossil species.Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Limidae Rafinesque 1815
No full textFamily Limidae Rafinesque, 1815 Remarks. There are few records of limids in the fossil seep record, with only three named species in three genera (two from Japan, Lima Cuvier, 1798 and Limatula Wood, 1839, and one from Svalbard, Pseudolimea Arkell in Douglas & Arkell, 1932). Lima zushiensis Yokoyama, 1920, was reported by Hirayama (1973) from a tentative seep-related fauna in the middle Miocene Hiranita Formation, and Amano & Kanno (1991) reported Limatula cf. (Limatula) vladivostokensis (Scarlato, 1955) and another indeterminate species of Limatula from the Pliocene Nadachi Formation. Hryniewicz et al. (2014) recently reported Pseudolimea arctica (Zakharov, 1966) from the Berriasian (local Ryazanian) Slottsmøya Member. No limid bivalve has been reported from modern New Zealand seep environments, although several genera are known from New Zealand waters inhabiting other marine environments in the present day (Spencer et al. 2009).Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Cardiidae Lamarck 1809
No full textFamily Cardiidae Lamarck, 1809 <p> <b>Remarks.</b> This family is not well represented in the seep fossil record, with the only reliable report being of indeterminate cardiids from a “ <i>Calyptogena</i> Association ” in the Pliocene Nadachi Formation, central Japan (Amano & Kanno 1991). Hirayama (1973) also reported the occurrence of <i>Clinocardium asagaiense</i> (Makiyama 1934) and <i>Papyridea</i> cf. <i>nipponica</i> Yokoyama, 1924, from the middle Miocene Hiranita Formation, central Japan, which may be seep-related.</p>Published as part of <i>Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Pratulum Iredale 1924
No full textGenus <i>Pratulum</i> Iredale, 1924 <p> Type species. <i>Cardium thetidis</i> Hedley, 1902</p> <p> <b>Remarks.</b> This genus has never been reported from modern New Zealand seeps or from fossil seep deposits globally. Traditionally, it has been regarded as a subgenus of <i>Nemocardium</i> Meek, 1876. However, Poorten (2013) recently reviewed <i>Nemocardium</i> and argued that <i>Pratulum</i> Iredale, 1924, should be elevated to genus level. This opinion is followed here.</p>Published as part of <i>Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Bathymodiolinae
No full textSubfamily Bathymodiolinae Kenk & Wilson, 1985 Remarks. Four new seep fossil mussel species have been formally described since this group was reviewed by Saether et al. (2010). Three have been assigned to the genus Bathymodiolus Kenk & Wilson, 1985. They are Bathymodiolus (s. l.) inouei Amano & Jenkins, 2011, from the early Oligocene Nuibetsu Formation, northern Japan, B. (s. l.) satsopensis Kiel & Amano, 2013, from the late Oligocene Lincoln Creek Formation, north-western USA, and B. (s. l.) aff. satsopensis Kiel & Amano, 2013 from the early Oligocene Makah Formation, north-western USA. The fourth new seep fossil mussel species, Vulcanidas ? goederti, was described by Kiel & Amano (2013) from the middle Eocene Humptulips Formation, north-western USA.Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

One specimen from Moonlight North (Y16/f0694), L4203 (holotype; Fig. 4), UOA. Remarks. Saether et al. (2010) originally described G. c o s e l i with unknown details of the anterior adductor scar. Further study of the holotype reveals that the anterior adductor scar is situated in the extreme anterior part of the shell, has a moderately strongly impressed anterior margin that closely follows the anterior margin of the shell, probably has a weaker posterior margin (seen weakly in one specimen, Fig. 4), and is rather narrow. These anterior adductor scar features are typical for the genus.Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Pulvinites
No full textcf. Pulvinites sp. (Fig. 5 A, B) Material. Five specimens from Moonlight North (Y16/f0694), large shell fragments, two numbered, L4650 (Fig. 5 A), L4651 (Fig. 5 B), UOA. Description. Shell large (up to ca. 70 mm at widest diameter), composed of very thin plates, outline irregular; dimpled texture observed on many of the plates, some plates more or less smooth without dimpled texture, some with calcitic lamellae. Remarks. Specimens are numerous at only one site, found in dense and diverse assemblages with caryophylliid corals, mytilids and thyasirids. It cannot be confirmed that the specimens belong to Pulvinites Blainville, 1824, with such internal features common to all species of this genus [e.g. posterior adductor muscle scar, anterior pedobyssal retractor muscle scar, byssal foramen, posterior pedal retractor muscle scar and suture (Palmer 1984; Tëmkin 2006)] not evident on any of the specimens, nor do any have the distinctive ligamental area preserved. However, the general morphology of the shelly plates closely resembles the nature of those of P. exempla (Fig. 5 C: cf. Marshall 1998; Tëmkin 2006).Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Pratulum quinarium Marwick 1944
No full textPratulum quinarium (Marwick, 1944) (Fig. 6) Nemocardium (Pratulum) quinarium Marwick, 1944: 266; pl. 36, figs. 10, 16. Material. Sixteen specimens, 12 numbered: two from Moonlight North (Y16/f0694), L4653 (Fig. 6 A), L4654 (Fig. 6 D); 14 from Tauwhareparae (Y16/f0539), L4655 (Fig. 6 C), L4656–4663, L4664 (Fig. 6 B), UOA. Remarks. Details of the muscle scars of Pratulum quinarium (Marwick, 1944) remained unobserved or unreported before this study, and are described here from a single small specimen (Fig. 6 A). The anterior adductor scar is elongate dorsoventrally, rather thin anteroposteriorly; posterior adductor scar arcuate, about twice as wide (anteroposteriorly) as anterior adductor scar, ca. 50% longer dorsoventrally, situated slightly lower than anterior adductor scar; pallial line entire, parallel to (antero- and postero-) ventral margin and rather distant from it (ca. 60– 70% towards margin from shell centre). The occurrence of P. quinarium at two Lillburnian-age New Zealand fossil seep sites extends the stratigraphic range of this species back from its previous earliest report in the Tongaporutuan. In fact, none of the species currently assigned to Pratulum have ever been recorded from the Lillburnian, but the genus is known throughout the Cenozoic from Danian to Recent (Beu & Maxwell 1990). P. quinarium is morphologically close to Pratulum pulchellum (Gray, 1843), distinguished from it by the finer and more numerous ribs, and by the narrow interstices, well developed transverse bars and absence of tubercles on the posterior area (Marwick 1944). At 11–13 mm in length, P. quinarium is among the smallest of New Zealand cardiids. The specimens were predominantly found in a single aggregation at Tauwhareparae, reflecting a gregarious habit that is typical for the genus.Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.

Propeamussiidae Abbott 1954
No full textFamily Propeamussiidae Abbott, 1954 Remarks. This family has been reported from fossil seep deposits only occasionally, but in four widely disparate areas of the globe: Greenland, Japan, New Zealand and USA. Campbell et al. (2008) reported the same specimen reported herein, and also tentatively identified it as belonging to the genus Parvamussium Sacco, 1897. Kiel (2006, 2010) reported tentative specimens of Catillopecten Iredale, 1939, and Propeamussium Gregorio, 1884, respectively, from Oligocene seeps of the Lincoln Creek Formation, north-western USA. The latter of these appears to be the most closely related to the specimen of this study. All other reports of the family in the seep fossil record have been of the genus Propeamussium. Kelly et al. (2000) provided a single report of an indeterminate species of the genus from the late Barremian Kuhnpasset Beds, north-eastern Greenland. The other reports are all from the early Campanian Yasukawa site of the Yezo Group, northern Japan, in which Propeamussium yubarense (Yabe & Nagao, 1928) has been identified (Amano et al. 2007; Jenkins et al. 2007b; Kiel et al. 2008a). Propeamussium is also known from the Whaingaroan (early Oligocene) to the Tongaporutuan (late Miocene) in New Zealand but is not present in the modern day. The pectinids Delectopecten fosterianus (Powell, 1933) and Veprichlamys kiwaensis (Powell, 1933) are the morphologically closest species that have been reported from modern New Zealand hydrocarbon seeps (Baco et al. 2010).Published as part of Saether, Kristian P., Jingeng, Sha, Little, Crispin T.
