|---|---|---|---|
This list of fossil molluscs described in 2025 is a list of new taxa of fossil molluscs that were described during the year 2025, as well as other significant discoveries and events related to molluscan paleontology that occurred in 2025.
Ammonites
Ammonite research
- A study on shell breakages in specimens of Hoploscaphites nicolletii from the Upper Cretaceous Fox Hills Formation (South Dakota, United States), interpreted as evidence of lethal attacks by durophagous predators, is published by Tajika et al. (2025).
Gastropods
Gastropod research
- A study on the evolution of the columellar folds in gastropods, based on data from extant and fossil taxa, is published by Vermeij (2025).
