Ammonites
[edit]Ammonite research
[edit]- 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).[1]
Gastropods
[edit]Gastropod research
[edit]- A study on the evolution of the columellar folds in gastropods, based on data from extant and fossil taxa, is published by Vermeij (2025).[2]
