### Jawless vertebrate research

* A study on the evolutionary history of hagfishes, as indicated by the fossil record and molecular data, is published by Brownstein & Near (2024), who consider the hagfish crown group to be a lineage with Early Permian origin and a long history in continental slope settings.
* Brookfield (2024) interprets Jamoytius kerwoodi as a probable detritivore or herbivore feeding on Dictyocaris (interpreted by the author as possible algal thalli).
* Evidence interpreted as indicating that oral plates of pteraspid heterostracans had a mechanical function and that the studied heterostracans likely had a bottom-dwelling feeding mode, such as deposit feeding or scavenging, is presented by Grohganz et al. (2024).
* A study on the structure of pteraspid oral plates and associated denticles is published by Grohganz et al. (2024), who interpret their findings as indicating that heterostracan oral plate denticles were not homologous with teeth of jawed vertebrates.
* Botella, Fariña & Huera-Huarte (2024) present evidence indicating that, in spite of lacking movable appendages other than tail fin, members of Pteraspidiformes were able to colonize the water column because the shape of their head shield made to possible for them attain high lift forces in a way similar to delta wings.
* Description of the feeding apparatus of Rhinopteraspis dunensis, interpreted as composed of 13 plates that were capable of rotating around the transverse axis, is published by Dearden et al. (2024), who interpret R. dunensis as a suspension or deposit feeder.
* Shan et al. (2024) describe new fossil material of "Dongfangaspis" qujingensis and Damaspis vartus from the Devonian Xishancun Formation (China), and reinterpret "D." qujingensis as a member of the genus Damaspis.

### Cartilaginous fish research

* 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.
* 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.
* A diverse assemblage of cartilaginous fish fossils is described from the Eocene Osinovaya Formation (Rostov Oblast, Russia) by Popov et al. (2024).
* 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).
* 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).
* Brownstein, Near & Dearden (2024) reconstruct the evolutionary history of holocephalans, and argue that, while key features of the holocephalan body plan evolved in the Paleozoic, the group entered deep ocean waters and diversified there only after the Cretaceous–Paleogene extinction event.
* Böttcher (2024) argues that preservation of isolated hybodont teeth without the root is most likely caused by resorption of the tooth root in members of Hybodontiformes.
* 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).
* 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).
* 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.
* 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).
* 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.
* Guinot et al. (2024) describe a new specimen of Palaeocarcharias stromeri from the Tithonian strata of the Canjuers Lagerstätte (France), providing new information on the anatomy of members of this species, and classify P. stromeri as a carpet shark that might be related to wobbegongs.
* 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).
* 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.
* Fossil material of mackerel sharks, including one of the youngest records of Cretoxyrhina mantelli reported to date, is described from the Campanian Duwi Formation (Egypt) by Yassin et al. (2024).
* 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.
* 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.
* Sternes et al. (2024) reevaluate the accuracy of the body form of Otodus megalodon inferred by Cooper et al. (2022), 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.
* Bateman & Larsson (2024) describe fossil material of Otodus megalodon from Georges Bank (Nova Scotia, Canada), possibly found at or near the northern range limit of the species.
* 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.
* 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).
* Greenfield (2024) coins the name Arthrobatidae as a replacement for the invalid name of the possible batomorph family Arthropteridae.
* 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; the assignment of this fossil material to Onchopristis is subsequently contested by Greenfield (2025).
* 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.
* 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).
* 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.

### Ray-finned fish research

* New, rank-free classification of extant and extinct ray-finned fishes is presented by Near & Thacker (2024).
* Dankina, Šečkus & Plax (2024) describe new fossil material of ray-finned fishes from the Devonian (Eifelian and Givetian) strata in Belarus and Lithuania, including scales of members of the genera Cheirolepis and Orvikuina, and improving biostratigraphic correlations within the studied region.
* New information on the evolution of the brain in the early ray-finned fishes, gained from the study of remains of the latest Carboniferous-earliest Permian ray-finned fishes from Brazil with extensive soft-tissue preservation of brains, cranial nerves, eyes and possible cardiovascular tissues, is presented by Figueroa et al. (2024).
* Redescription and study on the affinities of Westollia crassa is published by Štamberg (2024), who confirms the placement of this species as a distinct member of the family Aeduellidae.
* Bakaev (2024) designates a neotype of Eurysomus soloduchi, and interprets Eurysomus as a generalist feeder able to feed on hard prey.
* A study on teeth of members of Eurynotoidiformes is published by Bakaev et al. (2024), who interpret eurynotoidiforms as likely the oldest known actinopterygians specialized for herbivory.
