General research
- Evidence from the study of the fossil record of marine bivalves and gastropods from the Permian-Triassic transition, interpreted as indicating that taxonomic homogenization of the studied molluscs in marine communities after the Permian–Triassic extinction event was related to environmental changes that resulted in expansion of the preferred habitat of the survivors of extinction, is presented by Al Aswad et al. (2025).{{Cite journal |last1=Al Aswad |first1=J. A. |last2=Penn |first2=J. L. |last3=Monarrez |first3=P. M. |last4=Bazzi |first4=M. |last5=Deutsch |first5=C. |last6=Payne |first6=J.

- Evidence from the study of the fossil record of Early Jurassic gastropods and bivalves from the epicontinental seas of the north-western Tethys Ocean, indicative of a relationship between the thermal suitability of the studied animals and changes of their occupancy in response to climate changes during the Pliensbachian and Toarcian, is presented by Reddin et al.

- Aiba & Mochizuki (2025) describe new fossil material of ammonites and inoceramid bivalves from the Taneichi Formation (Japan), and interpret the composition of the studied assemblage as indicating that the middle Member of the Taneichi Formation was deposited during the Santonian–early Campanian.{{Cite journal|last1=Aiba |first1=D. |last2=Mochizuki |first2=T. |year=2025 |title=Ammonoids and inoceramid bivalves from the Upper Cretaceous shallow marine deposits of Taneichi Formation in Hirono Town, Iwate Prefecture, northeastern Japan: implication for biostratigraphy |journal=Cretaceous Research |at=106148 |doi=10.1016/j.cretres.2025.106148 |doi-access=free }}
- Fergusen, Reed & García-Bellido (2025) determine lost pigmentation patterns in molluscan specimens from the Miocene Cadell Formation (Australia), interpret the pigmentation patterns of Lophiotoma murrayana as supporting its reassignment from the genus Lucerapex to Lophiotoma, and interpret the pigmentation of Maoricolpus murrayanus as similar to the pigmentation of extant Maoricolpus roseus, strengthening the arguments that the two species are synonymous.{{cite journal|last1=Fergusen |first1=M.
