To date, Cretaceous nautilids from the Antarctic Peninsula have received little attention and only a single species had been reported, Eutrephoceras simile Spath, from Seymour, Snow Hill, and James Ross islands. Currently, it is considered a synonym of Eutrephoceras subplicatum (Steinmann), which has also been described from the Upper Cretaceous of central Chile, southern Argentina and Angola. Here, we report and describe E. subplicatum in detail, based on specimens from the Lower Campanian–Maastrichtian of Vega, Seymour and James Ross islands, presenting, for the first time, embryonic conch features related to the palaeoecology of these organisms. The nauta of this species had a diameter of approximately 30 mm with 5–6 septa. In addition, we describe a new species, Eutrephoceras antarcticum, and one specimen assigned to the same genus in open nomenclature, both recovered from the Lower Campanian beds of James Ross Island.

The Merchantville Formation of New Jersey, Maryland, and Delaware yields a distinctive assemblage of upper lower Campanian ammonites: Pachydiscus (Pachydiscus) sp., Pseudoschloenbachia cf. P. chispaensis Adkins, 1929, Placenticeras placenta (DeKay, 1828), Texanites (Texanites) sp., Menabites (Delawarella) delawarensis (Morton, 1830c), M. (D.) vanuxemi (Morton, 1830c), Menabites (Bererella) sp., Submortoniceras punctatum Collignon, 1948, S. uddeni Young, 1963, Cryptotexanites paedomorphicus n. gen. and sp., Glyptoxoceras sp., Chesapeakella nodatum n. gen. and sp., Baculites haresi Reeside, 1927, and Scaphites (Scaphites) hippocrepis (DeKay, 1828) III of Cobban, 1969. Elements of the fauna occur in the Gulf Coast and Western Interior regions of the United States, in Western Europe, and in Madagascar and provide a basis for correlation at this level.

Abstract. A new genus, Fingeria, is recognized among the globular-chambered trochospiral planktic foraminifera of the Upper Cretaceous (upper Cenomanian–lower Campanian). It consists of two pre-existing species: F. loetterlei (Nauss, 1947) and F. kingi (Trujillo, 1960). The ornamentation consists of scattered pustules, which can often fuse to form rugosities and, occasionally, costellae, especially over the earlier chambers of the test. Meridional ornamentation pattern is occasionally developed over isolated chambers. Fingeria is the only lineage of the whiteinellid stock that exhibits ornamentation coarsening and preferential orientation, which can be meridional or parallel to the periphery.
