Cartilaginous fish research
[edit]- Schnetz et al. (2024) study the completeness of the Paleozoic fossil record of chondrichthyans, finding it to be significantly lower compared to other investigated vertebrate groups.[31]
- A study on the diversification of chondrichthyans throughout the Paleozoic is published by Schnetz et al. (2024), who report evidence indicative of two increases of diversification rates in the earliest Devonian and in the earliest Carboniferous,and of dispersal into deeper-water environments in the aftermath of the Hangenberg event.[32]
- A diverse assemblage of cartilaginous fish fossils is described from the Eocene Osinovaya Formation (Rostov Oblast, Russia) by Popov et al. (2024).[33]
- A study on the anatomy of the pharynx of Acanthodes confusus, providing evidence of the presence of a mixture of characters seen in cartilaginous and bony fish, is published by Dearden, Herrel & Pradel (2024).[34]
- The first fossil material of obruchevodid petalodonts found outside the Bear Gulch Limestone, including teeth of Fissodopsis robustus and Netsepoye hawesi providing information on their three-dimensional tooth morphology, is described from the Carboniferous (Mississippian) Bangor Limestone (Alabama, United States) by Egli et al. (2024).[35]
- New hybodont assemblage, representing one of the oldest records of Jurassic hybodonts from Gondwana reported to date, is described from the Bajocian Jaisalmer Formation (India) by Ghosh et al. (2024).[36]
- The oldest fossil material of members of the genus Strophodus from Gondwana reported to date is described from the ?Early to Middle Jurassic succession of Kachchh Basin (India) by Bhosale et al. (2024).[37]
- Cuny & Chanthasit (2024) describe egg capsules of Palaeoxyris sp. from the Jurassic Phu Kradung Formation (Thailand), interpreted as indicating that at least some hybodont sharks in Jurassic Thailand reproduced in fresh waters.[38]
- Fossil material of Aegyptobatus kuehnei, formerly known only from the Bahariya Formation (Egypt), is described from the Alcântara Formation (Brazil) by Neves et al. (2024).[39]
- A study on the evolutionary history of selachians (modern sharks) is published by Sternes, Schmitz & Higham (2024), who argue that modern sharks expanded to the pelagic realm no later than the Barremian, that habitat influenced the morphology of their pectoral fins, and that the increase of sea surface temperature in the middle of the Cretaceous period was an important factor in driving the evolution of shark ecology and morphology.[40]
- The first fossil material of a member of the wobbegong genus Cederstroemia from Asia reported to date is described from the Santonian Kashima Formation (Japan) by Kaneko & Solonin (2024).[41]
- Vullo et al. (2024) describe new fossil material of Ptychodus from the Upper Cretaceous strata in Mexico, providing evidence that Ptychodus was a high-speed mackerel shark that likely fed on nektonic hard-shelled prey such as ammonites and sea turtles.[42]
- Shimada et al. (2024) describe two isolated teeth of Megalolamna paradoxodon from the Miocene Calvert Formation (Maryland, United States), representing the northernmost record of Megalolamna reported to date, and a tooth from the Oligocene Chandler Bridge Formation (South Carolina, United States) which might represent the geologically oldest record of a member of the genus Megalolamna reported to date.[43]
- Pollerspöck & Shimada (2024) describe fossil material of members of the genus Megalolamna from the Miocene strata in Austria, France, Germany and Italy, and interpret the type species of this genus, M. paradoxodon, as a junior synonym of "Otodus" serotinus Probst (1879), resulting in a new combination Megalolamna serotinus.[44]
- Sternes et al. (2024) reevaluate the accuracy of the body form of Otodus megalodon inferred by Cooper et al. (2022),[45] compare an incomplete vertebral column of a specimen of O. megalodon from the Miocene of Belgium with corresponding parts of the vertebral columns of extant white sharks, and argue that O. megalodon had an elongated body relative to the body of the white shark.[46]
- Paredes-Aliaga & Herraiz (2024) compare tooth microwear of the Miocene Otodus megalodon and the Pliocene great white shark from Spain, and interpret the two species as likely competing for similar prey, with the tooth wear of the great white shark possibly indicating the preference for a slightly more abrasive diet.[47]
- The first fossil tooth of a shark (great white shark) embedded in a seal bone reported to date is described from the Peace River Formation (Florida, United States) by Godfrey et al. (2024).[48]
- Greenfield (2024) coins the name Arthrobatidae as a replacement for the invalid name of the possible batomorph family Arthropteridae.[49]
- Capasso et al. (2024) describe rostrum of a large specimen of Onchopristis from the Maastrichtian Dakhla Formation (Egypt), providing evidence of persistence of Onchopristis in the marine environments of North Africa until the end of the Cretaceous.[50]
- Kocsis (2024) reviews the fossil record of Elasmobranchii from the Malay Archipelago and describes new fossils of elasmobranchs from the Miocene strata in Brunei and from the Sibuti Formation (Sarawak, Malaysia), including the first fossils of Chiloscyllium sp., cf. Hemitriakis sp., Paragaleus sp., the Borneo shark, the blacktip shark, Lamiopsis sp., Scoliodon sp. and Rhinobatos sp. from the Malay Archipelago reported to date.[51]
- Evidence from the study of dental microwear in extant chondrichthyans, interpreted as indicating that dental microwear analysis can provide reliable information on the diet of fossil taxa, is presented by Paredes-Aliaga, Botella & Romero (2024).[52]
- Cooper & Pimiento (2024) assess the functional diversity of sharks from 66 million years to the present using teeth, finding that shark functional diversity was high between the Palaeocene and its Miocene peak, and subsequently declined over the last 10 million years to its lowest value in the present. They interpret this decline as being due to the extinctions of functionally unique and specialised species such as †Otodus megalodon.[53]

- Review of the fossil record of non-marine members of Pycnodontiformes is published by Cawley & Kriwet (2024), who report that the incursions of pycnodontiforms into brackish and freshwater habitats increased during the Cretaceous period, when the rising sea levels might have made it easier for marine fishes to colonize continental environments.[107]
- Revision of evidence of growth and aging in the fossil material of pycnodonts is published by Capasso (2024), who find no evidence for a single overall pattern of somatic growth, but reports evidence of specific changes which seem to be common in the studied pycnodonts.[108]
- Capasso, Ebert & Witzmann (2024) review dental pathologies in pycnodonts, report uneven distribution of tooth anomalies in the pycnodont fossil record and interpret such distribution as suggesting that pycnodont teeth weren't initially ordered into distinct dental rows, which only appeared in the most derived forms.[109]
- Review of pathologies in the skeletons and dermal scales of pycnodont specimens is published by Capasso, Ebert & Witzmann (2024).[110]
- Capasso & Witzmann (2024) describe non-dental odontodes in two specimens of Haquelpycnodus picteti from the Cenomanian of Lebanon, representing the first record of dermal odontodes in pycnodonts reported to date, and interpret the anatomical position and structure of the studied structures as indicating that they functionally participated in the chewing process.[111]

- Redescription of Aphnelepis australis, based on data from a new specimen from the Talbragar fossil site (Australia), is published by Bean (2024), who assigns A. australis to the teleost family Archaeomaenidae.[119]
- Bennett (2024) describes a series of caudal vertebrae of an ichthyodectiform from the Upper Cretaceous Niobrara Formation (Kansas, United States), preserved with pathologies unknown in extant and fossil fishes but sharing similarities with diffuse idiopathic skeletal hyperostosis and spondylosis deformans of mammals, and interprets the studied pathologies as caused by combined bacterial and fungal infections, affecting the swimming abilities of the studied fish and likely ultimately resulting in its death.[120]
- Cantalice et al. (2024) describe fossil material of a previously unknown albuliform from the Campanian strata from the Múzquiz Lagerstätte (Austin Group; Coahuila, Mexico), estimated to be approximately 3,9 metres long and representing the largest albuliform reported to date.[121]
- A study on the phylogenetic relationships and biogeography of extant and fossil osteoglossids is published by Capobianco & Friedman (2024), who interpret their findings as indicating that the last common ancestor of extant osteoglossids was marine, and that the group colonized freshwater settings at least four times.[122]
- Liu et al. (2024) revise Osteochilus sanshuiensis, Osteochilus longipinnatus and Osteochilus laticorpus from the Paleogene Buxin Formation (China), synonymizing them into a single species named Jianghanichthys sanshuiensis.[123]
- Claeson et al. (2024) present a new reconstruction of Oncorhynchus rastrosus, interpreting its enlarged teeth as projecting laterally like tusks.[124]

- Redescription of Whitephippus tamensis is published by Davesne & Andrews et al. (2024), who interpret this taxon as an early member of Lampriformes, likely related to extant opahs and oarfishes and providing the earliest known evidence of adaptation of lampriforms to the pelagic environment.[126]
- Laine et al. (2024) sequence three-spined stickleback genomes from Late Pleistocene sediments from the Jossavannet lake (Finnmark, Norway), who identify more marine- than freshwater-associated ancestry in the studied genomes, but also find evidence that freshwater-associated alleles were already established at known loci of large effect during the brackish phase of the formation of the lake.[127]
- Miyata et al. (2024) describe an assemblage of marine fish otoliths from the Lower Cretaceous Kimigahama Formation (Japan), including the oldest known fossil material of members of the family Ichthyotringidae, as well as of otoliths of pterothrissine bonefishes, elopiforms and herring smelts indicative of cosmopolitan distribution of these groups during the Early Cretaceous.[128]
- Evidence from the skeletal and otolith fossil record, interpreted as indicative of presence of rich and diverse teleost assemblages in known Maastrichtian marine settings which were significantly affected by the Cretaceous–Paleogene extinction event, is presented by Schwarzhans, Carnevale & Stringer (2024), who also find that perciforms and related groups, ophidiiforms and gadiforms underwent an explosive radiation and diversification in the early Paleogene.[129]
- A study on the survivorship patterns of freshwater ray-finned fishes during the Cretaceous-Paleogene transition, based on data from the fossil record from the Denver Basin, is published by Wilson et al. (2024), who report evidence of previously unrecognized diversification of freshwater clades after the Cretaceous–Paleogene extinction event, as well as evidence of localized drops in diversity.[130]
