Bivalve research

[edit]
  • 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.[76]
  • Shi et al. (2025) report the first discovery of silicified bivalve fossils from the Permian (Kungurian−Roadian) strata of the Wandrawandian Siltstone (Australia), and reconstruct the taphonomic history of these fossils.[77]
  • Yang et al. (2025) report the first discovery of alatoconchid fossil material from the middle Permian strata of the Maokou Formation (Hubei, China).[78]
  • 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.[79]
  • A study on Early Triassic bivalve communities from the Liuzhi and Bozhou sections in Guizhou (China), providing evidence of increase of species diversity in associations dominated by members of the genus Claraia, but also evidence of broad ecological uniformity in the aftermath of the Permian–Triassic extinction event, is published by Yang et al. (2025).[80]
  • 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).[81]
  • Isaji (2025) redescribes "Unio" ogamigoensis and "Archaeounio" kagaensis, transfers the former species to the genus Margaritifera and the latter one to the genus Nakamuranaia, and determines the habitat preferences of the two species, interpreting M. ogamigoensis as living in rapidly flowing streams and N. kagaensis as living in shallow lakes on floodplains.[82]
  • 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).[83]
  • A study on the shell microstructure, ecology and biostratigraphic utility of Liostrea birmanica, based on fossil from the Middle Jurassic Daoban Formation (China), is published by Li et al. (2025).[84]
  • 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.[85]
  • Silva et al. (2025) describe new fossil material of bivalves from Lower Cretaceous deposits in northeastern Brazil, expanding known range of the genera Araripenaia, Cratonaia and Monginellopsis beyond the Crato and Romualdo formations.[86]
  • Mougola et al. (2025) report on the composition of the bivalve assemblage from the Upper Cretaceous (ConiacianSantonian) strata from Cap Estérias, including first records of three bivalve genera and twelve species from the Gabon Coastal Basin described to date.[87]
  • Evidence of changes of composition of Late Cretaceous bivalve communities from the Ariyalur Sub-basin (India), interpreted as likely related to changing substrate conditions, is presented by Mukhopadhyay et al. (2025).[88]
  • 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).[89]
  • 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.[90]
  • Bojarski, Cierocka & Szwedo (2025) report the discovery of more than 90 inclusions of piddocks in the Miocene Mexican amber, representing various developmental stages and at least five distinct morphotypes.[91]
  • Slattery et al. (2025) study the impact of different climate regimes on the evolution of members of the genus Nucula from the Late Cretaceous to the Quaternary, and find evidence that morphological change of the studied bivalves coincided with more stable climate conditions.[92]

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).[144]
  • A study on the Ordovician gastropod assemblage from the Mójcza Limestone Formation (Poland), differing in composition from assemblages from Gondwana and from the Perunica and Avalonia microcontinents and possibly resulting from local speciation, is published by Dzik (2025).[145]
  • 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.[146]
  • 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).[147]
  • A study on ecological niche preferences of turritelline gastropods during the Cretaceous-Paleogene transition, providing evidence of niche stability of turritellines living before and after the Cretaceous–Paleogene extinction event, is published by Goodman et al. (2025).[148]
  • Bakayeva et al. (2025) revise the colombellinid genus Zittelia, and recognize 9 valid species from southern and central Europe.[149]
  • Evidence from the study of extant and fossil members of the family Littorinidae, indicating that differences in shell shape are correlated with genetic distances in extant members of the group and may aid recognition of fossil taxa, is presented by Shin & Allmon (2025).[150]
  • Evidence from the study of polymeric membranes in shells of Ecphora gardnerae from the Miocene strata of the St. Marys Formation (Maryland, United States), indicative of peptide and chitin preservation in the studied specimens, is presented by Cleland et al. (2025).[151]
  • Fossil material of extant African taxa Acteon senegalensis and Acteon maltzani is described from the Pleistocene strata from the Taranto area by La Perna, De Santis & Caldara (2025), providing evidence of presence of both species in southern Italy during the Last Interglacial.[152]

General research

[edit]
  • New fossil material of molluscs, facilitating comparisons with faunas from other paleocontinents, is described from the Cambrian Stage 4 strata in North Greenland by Oh, Peel & Park (2025).[157]
  • 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).[158]
  • 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).[159]
  • Description of the assemblage of ammonites and inoceramid bivalves from the Albian strata from the Mangyshlak Anticlinorium (Kazakhstan) is published by Kennedy & Walaszczyk (2025).[160]
  • 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.[161]
  • 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.[162]
