During the early Maastrichtian, ammonite diversity dropped significantly with only two species recorded from the basal López de Bertodano Formation on Seymour Island. The subsequent diversification of endemic taxa and reappearance of long-ranging, widespread species into the basin resulted in an increase in ammonite diversity and abundance Cited by: Two species of the heteromorph ammonite genus Diplomoceras Hyatt are described from the Upper Cretaceous of the James Ross-Seymour Islands area, Antarctica. The late . Late Campanian–Maastrichtian Ammonite Fauna from Seymour Island (Antarctic Peninsula) extending from the late Campanian-Maastrichtian to the . This species exhibits a pandemic distribution throughout the latest Campanian–Maastrichtian, and in common with lower latitudes first appears in Antarctica in the late Campanian Sanctuary Cliffs Member of the Snow Hill Island Formation (Pirrie et al., , Olivero, a), remaining a common component of the ammonite fauna until directly.
Recently collected ammonite faunules from the Samhan Formation (Aruma Group) exposed south of Saiwan (Huqf Desert, Sultanate of Oman) comprise three species, Kitchinites angolaensis Howarth, , Pachydiscus (P.) arabicus Kennedy & Jagt sp. nov., and Manambolites dandensis Howarth, These taxa allow the middle and upper members of this formation to be dated as Late .
