Ammonite research
- A study on the swimming capabilities of ammonites, aiming to determine hydrodynamic costs and advantages provided by different conch geometries, is published by Ritterbush & Hebdon (2023).[8]
- 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]

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.[21]
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.[22]
- 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).[23]
