Ammonite research
- Đaković, Mrdak & Gawlick (2025) describe three assemblages of Anisian ammonoids from the Komarani and Bulog formations (Montenegro), including fossils of Ptychites rugifer, Megaphyllites obolus, Parakellnerites rothpletzi, Apleuroceras decrescens, Proteusites labiatus, Tropigastrites lahontanus, Proarcestes pannonicus, Proarcestes subtridentinus and Aristoptychites sp. extending known geographical ranges of these taxa.[13]
- Description and study on the biostratigraphy of the ammonite assemblage from the Jurassic strata from Sierra de Reyes (Mendoza Province, Argentina) is published by Riccardi, Gulisano & Gutierrez-Pleimling (2025).[14]
- A study on the composition of the Middle Jurassic ammonite fauna from the Shal Formation (Iran) is published by Majidifard & Wilmsen (2025).[15]
- A study on the morphology and growth of Rehmannia richei is published by Douas Bengoudira et al. (2025).[16]
- An ammonite specimen belonging to the genus Rehmannia, preserving paired Praetriaptychus aptychi within its body chamber and likely close to their original position, is described from the Jurassic (probably Callovian) strata from Quintanas de Hormiguera (Palencia, Spain) by Martínez, Ureta & García-Frank (2025).[17]
- Jantschke et al. (2025) report the discovery of a diverse ammonite assemblage from the Oxfordian strata of the Sengenthal Formation (Germany).[18]
- Cadena, Bustos & Lehmann (2025) describe bochianitid fossils from the Valanginian and Hauterivian strata of the Rosablanca Formation (Colombia), extending known range of Bochianites neocomiensis and Janenschites oosteri to the northern part of South America.[19]
- Fosso Menkem et al. (2025) describe fossil material of Albian ammonites from the Kribi-Campo sub-Basin (Cameroon), assign the fossil-bearing deposits to the Mundeck Formation, and interpret the studied fossils as evidence of a full connection between the North and South Atlantic during the lower Albian.[20]
- Wani (2025) studies morphology and ontogeny of Pachydesmoceras denisonianum on the basis of data from a conch from the Cretaceous Karai Formation (India), interpreted as indicating that constrictions and septal spacings are not always directly linked in the studied ammonite.[21]
- Xing et al. (2025) describe a new invertebrate assemblage from the Cretaceous amber from Myanmar, preserving ammonites alongside terrestrial arthropods.[22]
- A study on the ontogenetic shell development of Yabeiceras orientale, Y. cf. manasoaense, Forresteria yezoensis and F. muramotoi is published by Inose & Watanabe (2025).[23]
- 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).[24]

Bivalve research
- Gavirneni, Ivany & Reddin (2025) calculate resting metabolic rates for fossil bivalves, and find bivalves with higher mass-specific metabolic rates to be overall more vulnerable to extinction throughout the evolutionary history of the group.[43]
- Yang et al. (2025) report the first discovery of alatoconchid fossil material from the middle Permian strata of the Maokou Formation (Hubei, China).[44]
- Miao et al. (2025) study the fossil record of Triassic marine bivalves, and report evidence of recovery of taxonomic richness after the Permian–Triassic extinction event during the Early Triassic, and of recovery of ecological diversity in the Middle Triassic.[45]
- Evidence from the study of unionoid bivalve specimens from the Triassic of Poland and from the Cretaceous of Brazil and the United Kingdom, indicative of evolution of advanced anatomical traits of gills after the Triassic, is presented by Skawina & Ghilardi (2025).[46]
- Neubauer et al. (2025) identify the pectinid genus Velata Quenstedt (1857) as validly named and a senior synonym of Eopecten, and identify the type species of the genus Velata, "Spondylus" tuberculosus Goldfuss (1835), as a junior synonym of Velata abjecta (Phillips, 1829).[47]
- Simões et al. (2025) describe a new mollusc-dominated assemblage from the uppermost Romualdo Formation (Brazil), including freshwater bivalves previously known only from the underlying Crato Formation.[48]
- Mougola et al. (2025) report on the composition of the bivalve assemblage from the Upper Cretaceous (Coniacian–Santonian) strata from Cap Estérias, including first records of three bivalve genera and twelve species from the Gabon Coastal Basin described to date.[49]
- Evidence from the study of the fossil record of marine bivalves, indicating that the Cretaceous–Paleogene extinction event resulted in disruption of biodiversity of marine bivalves but did not fully determine their present-day diversity, is presented by Edie, Collins & Jablonski (2025).[50]
- Villegas-Martín et al. (2025) identify a fossil wood specimens from the La Meseta Formation (Antarctica), preserved with a boring interpreted as likely produced by a large-bodied member of the genus Kuphus, and representing possible evidence of wood colonization by large-bodied shipworms in the Antarctic Peninsula during the Eocene.[51]

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).[71]
- A study on the diversity of Permian and Triassic gastropods is published by Dominici (2025), who interprets increase of diversity of carnivorous gastropods during the Middle-Late Triassic transition as related to evolution of reef ecosystems at the same time.[72]
- Evidence from the study of fossil shells of Cathaica orithyia from the Chinese Loess Plateau, indicative of a link between shell morphology and changes in climatic and environmental conditions linked to changes of Asian summer monsoons over the past 470,000 years, is presented by Shen et al. (2025).[73]

Other molluscan research
- Redescription of the rostroconch species Hoarepora parrishi, based on data from new fossil material from the Moscovian Korobcheevo Formation (Ryazan Oblast, Russia) and Gzhelian Amerevo Formation (Moscow Oblast, Russia) that extends known geographical range of the species, is published by Mazaev (2025).[75]
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).[76]
- 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. (2025).[77]
- Description of the assemblage of ammonites and inoceramid bivalves from the Albian strata from the Mangyshlak Anticlinorium (Kazakhstan) is published by Kennedy & Walaszczyk (2025).[78]
- 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.[79]
- 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.[80]
