Fang, Zong-jie; Carter, Joseph G.
The identity of the Permian kalenterid Netschajewia Licharev, 1925 has been uncertain because its author indicated it could be
regarded as a replacement name for the preoccupied Modiolodon Netschajew, 1894 yet Newell (1957) treated Netschajewia as a subgenus of Stutchburia Etheridge Jr., 1900, and designated a type species different from that proposed by La Rocque and Newell (1969) for Modiolodon Netschajew. Netschajewia is confirmed as a replacement name for Modiolodon, thereby invalidating Newell’s (1957) erroneous type designation (misidentified type species) for Netschajewia. The names Ivanovia Astafieva-Urbajtis in Astafieva-Urbajtis and Ramovš, 1978 and Astafia Goncharova, 2013 are objective junior synonyms of Netschajewia. Netschajewia is definitely known only from its type species and one additional Permian species. It is assigned to the kalenterid subfamily Myoconchinae. The genus Verneuilnodon Fang & Carter, gen. nov. (subfamily Healeyinae Hautmann, 2008, reduced in rank herein from family Healeyidae) is proposed for Permian Mytilus (Modiola) pallasi de Verneuil, 1845, as restricted herein. The new Permian species, Kasimlara? antiqua (subfamily Healeyinae) is proposed. The wide circulation of Chavan’s (1969) republication of Newell’s (1957) erroneous type designation for Netschajewia means that modern references to this genus should be reevaluated.

Fuchs, Dirk
A comparative analysis shows that the gladius morphology of Boreopeltis helgolandiae Engeser & Reitner, 1985 (Aptian), the type species of Boreopeltis Engeser & Reitner, 1985, Boreopeltis sagittata (Naef, 1921) (Tithonian), and Boreopeltis smithi Fuchs & Larson, 2011 (Cenomanian) is fundamentally different from Boreopeltis soniae Wade, 1993 (Aptian). I therefore propose Eromangateuthis n. gen. in order to accommodate Eromangateuthis soniae (Wade, 1993).

Hammersburg, Sean Robert; Hasiotis, Stephen T.; Robison, Richard A.
The Spence Shale of northern Utah is the oldest North American middle Cambrian (~506–505 Ma) Burgess Shale-type (BST) deposit and, unlike previously thought for BST deposits, has a very diverse ichnofauna. Twenty-four ichnogenera and 35 ichnospecies were identified: Archaeonassa (A. fossulata and A. jamisoni isp. nov.), Arenicolites carbonaria, Aulichnites, Bergaueria (B. hemispherica and B.aff. perata), Conichnus conicus, Cruziana (C. barbata and C. problematica), Dimorphichnus, Diplichnites (D. cf. binatus, D. gouldi, andD.cf. govenderi), Gordia marnia, Gyrophyllites kwassizensis, Halopoa aff. imbricata, Lockeia siliquaria, Monomorphichnus (M. bilinearis,M.lineatus, and M. cf. multilineatus), Nereites cf. macleayi, Phycodes curvipalmatum, Phycosiphon incertum, Planolites (P. annularius, P.beverleyensis, and P. montanus), Protovirgularia (P. dichotoma and P. cf. pennatus), Rusophycus (R. carbonarius, R. cf. pudicus, and R. cf.cerecedensis), Sagittichnus lincki, Scolicia, Taenidium cf. satanassi, Teichichnus cf. nodosus, and Treptichnus (T. bifurcus, T. pedum, and T.vagans). The ichnofossils comprise three ichnocoenoses—Rusophycus-Cruziana, Sagittichnus, and Arenicolites-Conichnus—representingdwelling, deposit- and filter-feeding, grazing, locomotion, and predation behaviors of organisms (e.g., annelid worms and trilobites).Two ichnofossil associations are suggestive of predation: (1) Planolites terminating at a Rusophycus; and (2) Archaeonassa crosscuttinga Taenidium. The Spence Shale ichnofauna represent a distal Cruziana Ichnofacies and depauperate, distal Skolithos Ichnofacies. Anew ichnospecies of Archaeonassa is proposed, A. jamisoni isp. nov., and Ptychoplasma (Protovirgularia) vagans is herein transferred toTreptichnus. This study is the first ichnotaxonomic study of the Spence Shale and North American BST deposits and shows highlydiverse ichnofaunas can be present in BST deposits.

Stevensites, Zittelites, and Gyrophylloceras are proposed as replacement names for the preoccupied ammonite genera Stevensia Énay, 2009, Zittelia Tavera Benitez, 1985, and Gyrophyllites Wiedmann, 1963, respectively.
