Ammonite research

• Evidence indicating that morphologically complex ammonoid taxa often had reduced longevity and higher origination and extinction rates compared to morphologically simple ones is presented by Miao et al. (2024).
• Morón-Alfonso, Allaire & Ginot (2024) compare the results of application of two methods used to analyze the ammonoid whorl profile shape, interpreting different methods as better suited for taxa with highly defined umbilical walls and for ones with smooth umbilical walls or with reduced whorl overlap.
• A study on the affinities of "Tornoceras" baldisi, based on data from new specimens from the Chigua Formation (Argentina), is published by Allaire et al. (2024), who transfer this species to the genus Epitornoceras, and interpret the uppermost levels of the Chavela Member of the Chigua Formation preserving its fossils as Givetian in age.
• Piñeiro, Rodao & Núñez Demarco (2024) describe clusters of tiny ammonite shells from the San Gregorio Formation (Uruguay), found in nodules interpreted as reworked from underlying Devonian levels, and interpret this findings as possible evidence that ammonites laid eggs in floating or fixed gelatinous masses and hatched as miniatures of their parents that shared the same habitat with adult ammonites.
• A study on the origin of the Permian ammonite superfamily Popanoceratoidea is published by Leonova (2024).
• Description of the Olenekian ammonite assemblage from the Osawa Formation (Japan), interpreted as indicative of affinities with ammonite faunas from South Primorye and from the Tethys, is published by Shigeta, Endo & Inose (2024).
• Taxonomic revision of Carnian ammonites from the Polzberg Lagerstätte (Austria) is published by Lukeneder & Lukeneder (2024).
• Mironenko & Smurova (2024) describe ammonite specimens from the Jurassic localities in Russia preserved with the three-dimensional cameral membranes in their phragmocones which differed in their spatial arrangement and complexity from those known in other ammonites, and study the formation of all types of ammonite cameral sheets.
• Mitta & Mironenko (2024) describe a large-sized upper jaw of a member of the genus Lytoceras from the Bajocian strata from the Kuban basin (Karachay-Cherkessia, Russia), representing the oldest complete jaw of this type and the only upper jaw of a member of Lytoceratina reported to date.
• Sandoval (2024) describes fossil material of Latiwitchellia evoluta from the Middle Jurassic strata from the Betic Cordillera (Spain), representing the first known record of this species outside Eastern Pacific, and interprets this finding as indicating that westernmost Tethys and Eastern Pacific domains were connected through the Hispanic Corridor during the early Bajocian.
• The earliest occurrence of genus Macrocephalites known to date is reported from the Bathonian Kachchh Basin (India) by Jain (2024).
• Description of Late Jurassic ammonites from the Spiti Shale Formation of the Spiti and Zanskar regions of the Himalayas (India) is published by Bhosale et al. (2024).
• López-Palomino, Villaseñor & Palma-Ramírez (2024) study the affinities of Late Jurassic ammonites from the Santiago Formation (Mexico), providing evidence of biogeographic affinities with ammonites from Cuba, Chile and Argentina, as well as evidence of existence of the connection between the Tethys Ocean and the Pacific throughout the Oxfordian.
• A study on the relationship between septal complexity and ammonite diversity during the Cretaceous is published by Pérez-Claros (2024), who finds no evidence of a close relationship between oceanic anoxic events throughout the Cretaceous and worldwide evolutionary dynamics of ammonites.
• A study on changes of conch shape and septal spacing between successive chambers in Cretaceous ammonites from India, Madagascar and Japan throughout their ontogeny, interpreted as indicative of closer phylogenetic relationships between Perisphinctina and Ancyloceratina than with Lytoceratina or Phylloceratina, is published by Nishino et al. (2024).
• Frau et al. (2024) designate the neotype for the Early Cretaceous ammonite species Ammonites flexisulcatus, and assign this species to the desmoceratid genus Caseyella.
• A study on the morphological variation of specimens of Placenticeras from the Upper Cretaceous strata of the eastern Gulf Coastal Plain (mostly from Alabama, United States) is published by Mohr, Tobin & Tompkins (2024), who interpret the studied sample as including either a single species or two successive species, find no support for the recognition of Placenticeras and Stantonoceras as distinct genera, and report likely evidence of sexual dimorphism.
• Evidence from oxygen isotope values of shell material of Late Cretaceous ammonites from the Western Interior Seaway, interpreted as indicative of ~18 °C cooling from the Cretaceous Thermal Maximum in the Turonian until the late Maastrichtian, is presented by McCraw et al. (2024).
• A study on the diversification dynamics of Late Cretaceous ammonites is published by Flannery-Sutherland et al. (2024), who find evidence of regional differences of diversity trends, but no evidence of a progressive global decline through the Late Cretaceous.

Bivalve research

• Evidence indicative of different dynamics of the rates of origination and net diversification in infaunal and epifaunal bivalves throughout the Phanerozoic is presented by Foote, Edie & Jablonski (2024).
• Isozaki (2024) reports the first discovery of alatoconchid fossil material from the Capitanian strata from the Iwaizaki limestone (South Kitakami belt; Japan) and from the Chandalaz Formation (Sergeevka belt; Primorye, Russia).
• Evidence indicating that, in spite of significant decrease in taxonomic diversity, the functional diversity of bivalves of only slightly affected by the Permian–Triassic extinction event is presented by Wang et al. (2024).
• A study on the recovery of bivalves in the aftermath of the Permian–Triassic extinction event, providing evidence of an increase in endemicity beginning in the Middle Triassic, is published by Echevarría & Ros-Franch (2024).
• Moneer et al. (2024) revise Campanian Tethyan oysters from the North Eastern Desert of Egypt, who interpret the studied fossils as indicative of the primary migration pattern of oysters from the Southern Tethys margin towards the East–West direction, as well as indicative of a transition towards deeper environments during the middle-late Campanian.
• Pérez & Berezovsky (2024) study the phylogenetic affinities of Malarossia from the Eocene of Ukraine, recovering it as an early diverging genus within the carditid subfamily Scalaricarditinae.
• A study on the evolutionary history of Mediterranean bivalves across the Zanclean-Calabrian interval, providing evidence of less intense and more gradual loss of biodiversity than previously estimated and of more severe loss of biodiversity suspension feeders compared to infaunal deposit feeders, is published by Mondanaro, Dominici & Danise (2024).
• Campbell (2024) revises the bivalve fossil record from the Pleistocene Waccamaw Formation (United States), expanding known bivalve diversity from this formation.

Gastropod research

• A study on the phylogenetic relationships of members of Pleurotomariida is published by Karapunar, Höhna & Nützel (2024).
• Sun et al. (2024) describe fossils of large-bodied members of the genus Toxoconcha from the Middle Triassic Qingyan biota (Guizhou, China), estimating the largest specimen to have original height of around 350 mm.
• Merle, Goldstein & McKinney (2024) report cases of cannibalism in Crassimurex calcitrapa from the Eocene strata from the Paris Basin (France), representing the earliest occurrence of this behavior in the muricid fossil record.
• Evidence of preservation of intact polyene pigments in gastropod shells from the Miocene Vienna Basin (Austria and Hungary) is presented by Wolkenstein, Schmidt & Harzhauser (2024).
• A study on the diversity of Miocene gastropods from the Central Paratethys, providing evidence of a Middle Miocene species richness hotspot resulting from the formation of an archipelago-like landscape and the Middle Miocene Climatic Optimum, as well as evidence of subsequent decline in biodiversity related to the Middle Miocene disruption, is published by Harzhauser et al. (2024).
• Tattersfield et al. (2024) study the ecological associations of extant terrestrial gastropods from the Laetoli-Endulen area (Tanzania) and compare them with Pliocene gastropod assemblages from Laetoli, interpreting gastropods from the Lower Laetolil beds as indicative of semi-arid environment, those from the Upper Laetolil Beds as indicative of a mosaic of forest, woodland and bushland habitats, and gastropods from the Upper Ndolanya Beds as indicative of humid environment.
• Evidence of a complex evolution of body size in gastropods from western Atlantic throughout the Pliocene-Pleistocene transition is presented by Anderson et al. (2024).
• Evidence of coordinated response of endemic Microcolpia and Theodoxus prevostianus from Lake Pețea (Romania) to Late Glacial and Holocene climate changes resulting in lake level changes, thermal water pulses and changes of availability of calcium and magnesium in shell construction is presented by Gulyás & Sümegi (2024).

General research

• Wang et al. (2024) study Cambrian trace fossils assigned to the ichnogenus Climactichnites from the Elk Mound Group (Blackberry Hill, Wisconsin, United States), Archaeonassa from the Sellick Hill Formation (Australia) and Palaeobullia from the Buen Formation (Greenland), produced by animals moving on land millions of years before full terrestrialization, and interpret molluscs as most likely tracemakers; in the online supplemental material of the study the authors also argue that trace fossils from the Elk Mound Group assigned to the ichnogenus Protichnites resemble traces produced by marine gastropods, and that their asymmetry might be a result of chirality of mollusc shells.
• Antoine et al. (2024) report the discovery of fossil material from Kourou (French Guiana) providing evidence of the presence of diverse foraminifer, plant and animal communities near the equator in the 130,000-115,000 years ago time interval, including evidence of the presence of a diverse mollusc assemblage indicative of stronger affinities between Guianas and the Caribbean than today.
