Shigeta & Maeda (2023) describe new fossil material of ammonites from the Maastrichtian Krasnoyarka Formation (Sakhalin, Russia), including fossils of Zelandites varuna, Gaudryceras seymouriense, Pachydiscus subcompressus and Anagaudryceras mikobokense, and interpret the presence of these species as indicative of the influx of immigrant ammonite species into the Northwest Pacific region during late Maastrichtian, which might have been associated with cooling after the greenhouse Middle Maastrichtian Event.[9]

A study aiming to determine the metabolic rates of ammonites and nautiloid cephalopods living at the end of the Cretaceous is published by Tajika et al. (2023), who find that the nautiloid Eutrephoceras had a lower metabolic rate than co-occurring ammonites, and argue that the lower metabolic rate in nautiloids might have been an advantage during the Cretaceous–Paleogene extinction event.[13]

Other mollusc research

Qiang et al. (2023) describe new fossil material of Anabarella plana from the Cambrian Yanjiahe Formation (China), and consider A. plana to be the only member of the genus Anabarella definitely present in South China.[36]

General research

Slater (2023) describes microscopic molluscan radulae from the Cambrian (Wuliuan) Borgholm Formation (Sweden), similar to the radulae of extant gastropods specialized for piercing and sucking the tissues of green algae, and interpret this finding as indicating that this form of herbivory was already present among Cambrian molluscs.[37]
A diverse molluscan assemblage dominated by turritellid gastropods from Kachchh (India), originally interpreted as Late Jurassic in age, is reinterpreted as more likely Miocene in age by Fürsich et al. (2023).[38]
