* Redescription of the anatomy of the skull of Acynodon adriaticus is published by Muscioni et al. (2024).
* Rocchi & Vila (2024) describe fossil material of Allodaposuchus cf. subjuniperus from the lower Maastrichtian deposits of the Suterranya-Mina de lignit locality (La Posa Formation; Lleida, Spain), providing evidence of the presence of a third early Maastrichtian species of Allodaposuchus (in addition to A. palustris and A. hulki) in the Tremp Group.

* Purported sebecosuchian teeth from the Pliocene Otibanda Formation (Papua New Guinea) are reinterpreted as more likely to be mekosuchine teeth by Ristevski, Molnar & Yates (2024).
* Review of the fossil record and osmoregulation of members of Alligatoroidea is published by Stout (2024), who argues that fossil members of the group might have been salt-tolerant and more ocean-going than extant alligatoroids.
* Redescription of Arambourgia gaudryi is published by Conedera et al. (2024), who recover A. gaudryi as an alligatorine, and interpret it as a semi-terrestrial animal.
* Paiva et al. (2024) recostruct ancestral body sizes across the evolutionary history of caimanines, and interpret evolution of large body sizes in the lineages including Mourasuchus and Purussaurus as related to warmer climatic conditions with less seasonal temperature variation in the western Amazonian region of South America during the Miocene.
* A study on the skull anatomy of Eosuchus lerichei is published by Burke et al. (2024), who report possible evidence of the presence of salt glands, and interpret Eosuchus as a gavialoid that wasn't closely related to "thoracosaurs".
* Redescription of Crocodylus palaeindicus and a study on the phylogenetic relationships of members of Crocodyloidea is published by Chabrol et al. (2024), who consider Crocodylus sivalensis to be a junior synonym of C. palaeindicus, find evidence of a close relationship of Crocodylus checchiai and Crocodylus falconensis with extant American crocodiles, recover Kinyang as a crocodyline rather than osteolaemine, recover Albertosuchus knudsenii, Prodiplocynodon langi and "Crocodylus" affinis outside Crocodyloidea, and consider an alligatoroid placement for the clade Orientalosuchina to be highly labile.

* A study on diversity of Mesozoic dinosaurs throughout their evolutionary history is published by Mannion (2024).
* Review of main obstacles in the study of neurology of Mesozoic dinosaurs, and of advances in the study of dinosaur neurology, is published by Balanoff (2024).
* Evidence indicating that the evolution of rostral keratin cover was associated with partial tooth reduction throughout the evolutionary history of dinosaurs, but does not explain the complete loss of teeth in dinosaur lineages, is presented by Aguilar-Pedrayes, Gardner & Organ (2024).
* A study on the evolutionary rates of biting mechanics in herbivorous dinosaurs is published by Kunz and Sakamoto (2024), who interpret their findings as indicating that biomechanic evolution rates can reveal ecological signatures in different lineages and ontogenetic stages.
* Caspar et al. (2024) present revised estimates of encephalization and telencephalic neuron counts in dinosaurs, contesting neuron count and relative brain size estimates presented in the study of Herculano-Houzel (2023), and in particular contesting estimates of exceptional neuron counts and relative brain size in large-bodied theropods compared to other dinosaurs presented by the cited author.
* Evidence from the study of an ontogenetic series of endocasts of Psittacosaurus lujiatunesis and immature specimens of other non-avian dinosaur taxa, interpreted as indicating that non-avian dinosaurs had a distinct developmental trajectory of the brain compared to extant birds and crocodilians, is presented by King et al. (2024).
* Atterholt et al. (2024) report evidence of widespread presence of bony ridges in the neural canals in the caudal vertebrae of non-avian dinosaurs, and interpret the studied structures as likely bony spinal cord supports.
* A study on the evolution of the dinosaurian climatic niche landscape throughout the Mesozoic is published by Chiarenza et al. (2024), who report that the distribution of sauropodomorphs indicates their preference for warm environments, while ornithischians and theropods explored a broader range of environments with varied climates, and interpret the colonization of areas with colder climates by theropods since the Early Jurassic as likely related to the evolution of endothermy.
* Upchurch & Chiarenza (2024) review the studies of the biogeography of non-avian dinosaurs.
* Qvarnström et al. (2024) reconstruct food webs from five tetrapod communities from the Late Triassic and Early Jurassic of Poland on the basis of data from bromalites, and interpret changes in bromalite morphologies and their contents as related to shifts in faunal composition, with increased abundance of dinosaurs coinciding with decline of formerly dominant tetrapod groups; the authors also interpret their findings as indicating that early herbivorous dinosaurs had different feeding habits than dicynodonts and aetosaurs, and interpret the studied fossils as recording stepwise rise of dinosaurs to supremacy across 30 million years of evolution.
* Putative bone fragments of large-bodied dinosaurs from Rhaetian strata in France, Germany and United Kingdom are reinterpreted as fossil material of large-bodied ichthyosaurs by Perillo & Sander (2024).

* Tracks of medium to large theropods and small ornithopods are described from the Lower Cretaceous (Valanginian-Aptian) Wonthaggi Formation (Victoria, Australia) by Martin et al. (2024), confirming the presence of large theropods in the polar regions of Australia during the Early Cretaceous.
* Bandeira et al. (2024) revise dinosaur remains from the Lower Cretaceous Massacará and Ilhas groups (Recôncavo Basin, Brazil) collected between 1859 and 1906, and interpret the studied fossils as indicative of the presence of an Early Cretaceous dinosaur assemblage including theropods, sauropods and ornithopods.
* New dinosaur tracksite, preserving ornithopod, sauropod and theropod tracks, is described from the Lower Cretaceous (Aptian-Albian) Duoni Formation (Tibet, China) by Li et al. (2024).
* Navarro et al. (2024) report the discovery of a new tracksite preserving theropod, sauropod and ornithischian footprints from the Cenomanian–Turonian Santo Anastácio Formation (Brazil), representing the first dinosaur ichnofauna from the Bauru Group reported to date and providing evidence of presence of ornithischians in the studied area before environmental changes during the Cenomanian–Turonian interval.

(2024), who diagnose the fusion of two caudal vertebrae of the holotype specimen of Aucasaurus garridoi as congenital malformation and diagnose partial fusion of five caudal vertebrae of the holotype of Elemgasem nubilus as spondyloraptropathy, in both cases representing the first occurrences of the diagnosed pathologies among non-tetanuran theropods.

* The purported abelisaur ilium from the Upper Cretaceous Kem Kem Group (Morocco) described by Zitouni et al.

* Myhrvold et al. (2024) use statistical analyses to reconsider previous descriptions by Fabbri et al. (2022) of spinosaurs such as Spinosaurus as subaqueous foragers, and provide evidence that Spinosaurus was likely not an aquatic pursuit predator.

* A study on three bonebeds from the Upper Cretaceous Oldman Formation (Alberta, Canada) and Two Medicine Formation (Montana, United States) preserving remains of specimens of Hypacrosaurus stebingeri is published by Joubarne, Therrien & Zelenitsky (2024), who interpret the studied assemblages as indicating that H. stebingeri individuals lived in age-segregated groups until into their fourth year of life.
* Evidence from the study of a skull of a juvenile hadrosaurine from the Campanian Dinosaur Park Formation (Alberta, Canada), interpreted as indicative of differences in the dental battery development between hadrosaurid species which might have been related to dietary differences during early ontogeny, is presented by Warnock-Juteau et al. (2024).
* Sharpe et al. (2024) describe fossil material of a probable immature specimen of Edmontosaurus regalis from the Horseshoe Canyon Formation, and interpret its similarities to Ugrunaaluk kuukpikensis as supporting the referral of the Alaskan saurolophine material to Edmontosaurus cf. regalis.
* Wick & Lehman (2024) describe fossil material of a juvenile pachycephalosaur specimen belonging to the genus Stegoceras from the Campanian Aguja Formation (Texas, United States), providing new information on the ontogeny of members of this genus, and interpret the holotype of Texacephale langstoni as a probable adult individual belonging to the genus Stegoceras.

* A study on the bone histology of Yinlong downsi is published by Han et al. (2024), who report evidence indicating that Y. downsi reached sexual maturity earlier than Psittacosaurus but later than ceratopsids, and evidence of growth rates higher than those of extant squamates and crocodiles but lower than those of large-sized dinosaurs and extant mammals and birds.

* Yang et al. (2024) describe a well-preserved scaled skin of a specimen of Psittacosaurus from the Early Cretaceous Jehol Biota of China, providing evidence of preservation of epidermal layers, corneocytes and melanosomes, and interpret the studied specimen as indicative of co-occurrence of feathers and reptile-type skin in non-feathered regions of the skin in Psittacosaurus.

### Avian research

* A study performing quantitative functional imaging of the brain during rest and flight in rock doves with implications for the evolution of avian flight is published by Balanoff et al. (2024). They found increased neural activity in the cerebellum during flight, and through comparisons with cranial endocasts of extinct theropods, suggest that cerebellar expansion underlying such activity occurred at the base of Maniraptora, prior to the origin of avian flight.
* The Cretaceous fossil record of avialans from China is reviewed by Zhou & Wang (2024).
* Evidence of gradual and sequential moult of wing flight feathers in two probable members of Confuciusornithiformes from the Lower Cretaceous Yixian Formation (China) is presented by Wang et al. (2024).
* A morphometric study of a large sample of specimens of Confuciusornis sanctus is published by Zhou et al. (2024), who interpret their findings as indicative of the presence of sexual dimorphism in this species.
* The fossil record of avialans from the Upper Cretaceous Maastricht Formation (Belgium and the Netherlands) is reviewed by Field et al. (2024), who additionally present new data on the bone histology and hindlimb length of Asteriornis maastrichtensis.
* Stoicescu et al. (2024) describe partial femur of an avialan belonging or related to the species Elopteryx nopcsai from the Maastrichtian strata at the Nălaț-Vad locality (Romania), interpret E. nopcsai as a probable secondarily flightless avialan, and argue that Balaur bondoc might be a junior synonym of E. nopcsai.
* A study the relationship between the morphology of cervical vertebrae and dietary modes in extant and extinct birds is published by Liu et al. (2024), who report that Bohaiornis, Brevirostruavis and Longipteryx had cervical morphologies resembling those of extant insectivorous or raptorial birds, while Yanornis and Iteravis had cervical morphologies closer to those of extant generalist or herbivorous birds, falling into the ecological niches of aquatic or semiaquatic birds.
* New information on the development of the skeletons of members of Enantiornithes throughout their ontogeny, based on the study of two early immature specimens from the Lower Cretaceous Jiufotang Formation (China), is presented by O'Connor et al. (2024).
* O'Connor et al. (2024) report the discovery of gymnosperm seeds within the abdominal cavities of two specimens of Longipteryx, providing evidence of frugivory of Longipteryx.
* A study aiming to determine the diets of members of the family Bohaiornithidae is published by Miller et al. (2024), who interpret their findings as indicating that the family included taxa adapted to diverse diets, and predict the ancestral member of Enantiornithes to have been a generalist which ate a wide variety of foods.
* A study on the limb bone histology and growth dynamics of Musivavis amabilis is published by Kundrát et al. (2024).
* The Cretaceous fossil record of avialans from Antarctica is reviewed by Acosta Hospitaleche et al. (2024).
* Álvarez-Herrera & Agnolín (2024) compare Maastrichtian bird assemblages from Santa Cruz Province, Argentina and from Antarctica, note that the asseblanges differ in composition (only members of Neornithes and kin are present in Antarctica, unlike in Argentina), and interpret those differences as possibly caused by accelerated growth and high metabolism of members of Neornithes compared to more basal birds.
* A study on the antiquity of the crown group of birds is published by Brocklehurst & Field (2024), who argue that the crown group originated between 110.5 and 90.3 million years ago, and that the majority of higher-order diversification within the crown group either spanned or postdated the Cretaceous-Paleogene transition.
* A study on patterns of avian molecular evolution is published by Berv et al. (2024), who interpret their findings as indicating that the Cretaceous–Paleogene extinction event influenced the evolution of bird genomes, physiology and life history traits that in turn influenced the diversification of modern birds.
* Widrig, Navalón & Field (2024) describe the external and internal morphology of the braincase of Lithornis vulturinus, interpret its neuroanatomy as likely similar to the neuroanatomy of the ancestral crown bird, and interpret L. vulturinus as a diurnal bird that likely was reliant on visual cues and had a well-developed sense of smell.
* The histochemistry of an ostrich eggshell from the Miocene Liushu Formation (China) is examined by Wu et al. (2024).
* Pickford, Russell & Day (2024) designate a lectotype for the oospecies Psammornis rothschildi.
* Schroeter (2024) presents a characterization of diagenetiforms in a moa proteome.
* Review of moa tracks and other traces is published by Hunt & Lucas (2024), who name new ichnotaxa Turanganuipus worthyi,Moapus tennysoni, Dinornipus oweni, Gisbornepus angustus, Tutaenuipus woodi and Aotearoapus lockleyorum.
* Pickford (2024) revises fossil eggshells from the Miocene strata from the Karingarab aeolianite succession (Namibia), originally described as Struthio karingarabensis, and transfers this oospecies to the genus Diamantornis.
* A draft genome of the little bush moa is presented by Edwards et al. (2024).
* Tomlinson et al. (2024) reconstruct the range and extinction dynamics of six species of moa, and interpret their findings as indicating that the studied species likely had similar spatial patterns of geographic range collapse, and that their final populations persisted in cold, mountainous areas that continue to function as sanctuaries for New Zealand's remaining flightless birds.
* Fossil material of a possible member of Galloanserae is described from the Upper Cretaceous (Maastrichtian) Lance Formation (Wyoming, United States) by Brownstein (2024), who interprets this finding as supporting a cosmopolitan distribution of early crown birds.
* Crane et al. (2024) reevalute the anatomy of the mandible of Asteriornis maastrichtensis and find that no retroarticular process (a trait originally interpreted as supporting the placement of A. maastrichtensis within Galloanserae) is preserved in the holotype, which does not preserve the caudal extremities of the mandibles; however, the authors do not rule out the possibility that the studied bird originally had robust retroarticular processes comparable to those of extant members of Galloanserae, and their phylogenetic analysis supports the placement of Asteriornis within Galloanserae.
* Mayr et al. (2024) describe a new skull of a gastornithiform bird from Geiseltal (Germany) and assign it to the species Diatryma geiselensis, interpreted by the authors as distinctly different from Gastornis parisiensis, and advocate reestablishment of Diatryma as a genus distinct from Gastornis.
* McInerney, Blokland & Worthy (2024) redescribe the skull morphology of Genyornis newtoni and study its phylogenetic affinities, recovering the family Dromornithidae as more likely to be members of Anseriformes related to screamers than close relatives of the family Gastornithidae.
* A study on the vertebral column of Annakacygna hajimei is published by Matsuoka, Seoka & Hasegawa (2024), who reconstruct the neck of this bird with a curve at its base that increased the buoyancy and stability of the bird's body when it was in the water by helping it to put the base of the neck with its air sacs below the water surface.
* A case for the validity of Miotadorna catrionae is presented by Tennyson et al. (2024), in response to Worthy et al. (2022) considering it a junior synonym of Miotadorna sanctibathansi.
* Evidence from the study of mitogenomes of the extant Brazilian merganser and extinct Auckland Island merganser, interpreted as indicating that the studied mergansers are not sister taxa and that their ancestors moved into the Southern Hemisphere in two separate colonization events at least 7 million years ago, is presented by Rawlence et al. (2024).
* A study on the evolutionary history of neoavians, as indicated by genomic data, is published by Wu et al. (2024), who argue that the initial diversification of the crown group of birds was correlated with the rise of flowering plants in the Cretaceous, that modern birds survived the Cretaceous–Paleogene extinction event relatively well, and that the Paleocene–Eocene Thermal Maximum had a significant impact on the diversification of the seabirds; Claramunt et al. (2024) subsequently considered these results to be questionable, arguing that the study has problems with their choices of fossils and calibration strategy, while Wu et al. (2024) rejected these criticisms.
* A study on the impression of the skeleton of a small flamingo described from the late Cenozoic Pie de Vaca site (Mexico) is published by Galicia-Coleote, Cruz & Eduardo Corona-M (2024), who interpret the studied imprint as representing an adult flamingo different from known the American extant and extinct species, providing evidence of the presence of a group of small flamingos in the late Cenozoic of North America.
* Revision of the systematics and nomenclature of the dodo, the Rodrigues solitaire and the family-group nomina based upon them is published by Young et al. (2024), who name the new subtribe Raphina for the two taxa.
* Zelenkov (2024) describes a fragmentary humerus of a buttonquail from the Lower Pleistocene strata from the Taurida Cave (Crimea), representing the first record of a member of the family Turnicidae from Eurasia from the Pliocene to Middle Pleistocene interval.
* Goodman & Rasolonjatovo (2024) study the carpal spur of the Malagasy lapwing, find it to be larger than wing spurs of living lapwings, and interpret it as likely used for defence against predators.
* Abbassi et al. (2024) describe an assemblage of vertebrate footprints from the Oligocene Lower Red Formation (Iran), including footprints of small shorebirds and possible herons and storks.

* Guilherme et al. (2024) report the first discovery of the left tibiotarsus of Macranhinga ranzii from the Miocene Solimões Formation (Brazil), and estimate the body mass of the studied darter as ranging from 14.39 to 19.1 kg.
* Zelenkov et al. (2024) describe fossil material of a large marine bird from the Eocene Tavda Formation (Tyumen Oblast, Russia), interpreted as evidence of a worldwide distribution of stem albatrosses or similar large procellariiforms as early as the Eocene.

* A new specimen of Palaeeudyptes is described by Xia, Pei & Li (2024).
* A study on the long limb bone microstructure of extant king penguins throughout their ontogeny is published by Canoville, Robin & de Buffrénil (2024), who find evidence of substantial intraspecific variability regardless of the ontogenetic stage, and evidence indicating that limb bones of king penguins reach adult size early in the development while their microstructure continues to change until adulthood; on the basis of their findings the authors do not consider the conclusions of Cerda, Tambussi & Degrange (2014) and Ksepka et al. (2015) about the paleobiology of fossil penguins to be properly supported by their data.
* The evolutionary dynamics of microsatellites in Adélie penguins based on both modern and ancient genetic samples (up to 46.5 thousand years old) are studied by McComish et al. (2024).
* Torres Etchegorry & Degrange (2024) reconstruct endocast of Argentavis magnificens, and interpret its probable brain morphology as suggesting that Argentavis was a scavenger or even a kleptoparasitic bird, living in open areas without much vegetation.
* Leoni et al. (2024) describe the first fossil material of a turkey vulture from cave deposits in northeastern Brazil, which preserves trace marks likely produced by a felid and indicating that the vulture died in the cave it was discovered in.
* A study on the age of remains of California condors from the Mule Ears Peak Cave (Texas, United States) is published by Emslie (2024), who find evidence of the presence of condors at the studied site beginning at ~15,000 calendar years before present and evidence of definite nesting ~13,000 calendar years before present, reports evidence from stable isotope analysis of bone collagen interpreted as indicating that the studied condors fed on megafauna living in a desert grassland ecosystem, and interprets these findings as indicating that the disappearance of the California condor from the inland west of North America as related to the extinctions of megafauna the end of the Pleistocene.
* The colonization of the Mediterranean Basin by Bonelli's eagle is studied by Moleón et al. (2024), drawing on data from environmental favorability, genetic structure, the fossil record, and ecological relationships with golden eagles.
* Acosta Hospitaleche & Jones (2024) describe fossil material of a large-bodied (with an estimated body mass of around 100 kg) phorusrhacid or phorusrhacid-like bird from the Eocene La Meseta Formation (Seymour Island, Antarctica), interpreted by the authors as likely apex predator of Antarctica during the Eocene.

* De Pietri et al. (2024) report evidence of the presence of 10 and 17 passerine species in the Miocene St Bathans fauna (New Zealand), including a honeyeater larger than extant tui and a cracticid comparable in size to extant Australian magpie.
* Pöllath & Peters (2024) study the composition of early Holocene bird assemblages from southeast Turkey, northern Syria and northern Iraq, providing evidence of changes of bird species ranges related to climatic changes during the Pleistocene-Holocene transition, aridification during the Holocene and human activities.
* Evidence of disproportionate loss of global bird diversity resulting from extinction caused by human activities since the Late Pleistocene is presented by Matthews et al. (2024).

### Pterosaur research

* A study on the morphological diversity of hands and feet of pterosaurs throughout their evolutionary history is published by Smyth et al.

* Yun (2024) uses geometric morphometric analyses to investigate the relationships of pterosaur specimens from the Early Cretaceous Jinju and Hasandong formations (South Korea), and suggests that the material likely cannot be assigned to the Boreopteridae, as had previously been assumed.
* Cooper, Smith & Martill (2024) study fossilized gut contents of specimens of Dorygnathus banthensis and Campylognathoides zitteli from the Posidonia Shale (Germany), reporting evidence of Dorygnathus feeding on fishes and evidence of Campylognathoides feeding on belemnites.
* Habib & Hone (2024) study the variation seen in elements and body parts of specimens of Rhamphorhynchus muensteri, providing evidence of high levels of constraint throughout the appendicular and axial elements that were likely important for flight, and evidence of increased variability of tails of larger individuals, possibly related to the signalling function of the tail.
* Evidence from the study of tail vanes of specimens of Rhamphorhynchus muensteri from the Solnhofen Limestone (Germany), providing evidence of the presence of thicker tube-like structures criss-crossing with thinner fibres, is presented by Jagielska et al.

* Heredia et al. (2024) describe new tracks of pterodactyloid pterosaurs from the Cenomanian Candeleros Formation (Argentina) with a different morphology from previously recorded tracks from this formation, interpreted as more likely produced by individuals of different ages rather than different species.
* Smyth & Unwin (2024) interpret Pterodactylus antiquus and Diopecephalus kochi as distinct pterodactyloid taxa that were not closely related.
* Partial finger phalanx of a member of Ctenochasmatoidea with an estimated wingspan of at least 3 m, representing one of the first records of Jurassic pterodactyloids from the United Kingdom, is described from the Kimmeridge Clay of Abingdon, Oxfordshire by Etienne et al. (2024).
* Description of the anatomy of the ankle of Pterodaustro guinazui is published by Burlot et al. (2024).
* Redescription and a study on the affinities of Haopterus gracilis is published by Xu, Jiang & Wang (2024), who recover H. gracilis as a member of Istiodactyliformes.
* Hone et al. (2024) report that the fossil material assigned to Luchibang xingzhe is a composite including remains of two pterosaurs, restrict the holotype to the rostrum and anterior mandible and consider this fossil material to be sufficient to confirm that L. xingzhe was a valid istiodactylid taxon, and interpret the purported postcranial material of L. xingzhe as remains of an indeterminate member of Azhdarchomorpha.
* Ciaffi & Bellardini (2024) describe isolated teeth of indeterminate members of Ornithocheiriformes from the Lohan Cura Formation (Neuquén Province, Argentina), providing evidence of a more abundant and diversified ornithocheiriform fauna in the south of the Neuquén Basin (at least in the Albian) than previously known.
* A study evaluating the ability of different proposed take-off motions of pterosaurs to produce leverage during the launch phase, as indicated by tests using a musculoskeletal model based on an indeterminate ornithocheiraean pterosaur with a 5 m wingspan, is published by Griffin et al. (2024).
* Cadena, Atuesta-Ortiz & Wilson Mantilla (2024) describe pterosaur fossil material from the Valanginian Rosablanca Formation and the Barremian Paja Formation (Colombia), including fossil material of an Anhanguera-like specimen extending known fossil record of such pterosaurs into the earliest part of the Cretaceous.
* Redescription of the anatomy of the postcranial skeleton of Dsungaripterus weii is published by Song, Jiang & Wang (2024).
* Large pterosaur footprints, likely produced by Dsungaripterus weii, are described from the Lower Cretaceous strata from the Junggar Basin (Xinjiang, China) by Li et al. (2024), who name a new ichnotaxon Pteraichnus junggarensis and study the relationship between pes length and hip height in pterosaurs.
* Jung & Huh (2024) describe pterosaur tracks from the Turonian Jangdong Formation (South Korea), interpreted as likely produced by small-bodied or immature azhdarchids and as probable evidence of gregariousness of the trackmakers.

### Other archosaur research

* Garcia et al. (2024) describe two new lagerpetid specimens from the Carnian strata of the upper Santa Maria Formation (Brazil), interpreted as indicative of a sympatric occurrence of lagerpetids representing different morphotypes.
* Agnolín et al. (2024) revise the anatomy of the pelvic girdle of Lagerpeton chanarensis, reinterpreting it as likely to have a sprawling gait.
* A study on the anatomy of the skeleton and musculature of the hindlimbs of Lagosuchus talampayensis is published by Otero, Bishop & Hutchinson (2024), who find that the fossil material of L. talampayensis is curated with skeletal elements of members of other taxa, and estimate moment-generating capacities of reconstructed musculature.

## General research

* A study on the evolution of locomotion in archosauromorph reptiles is published by Shipley et al. (2024), who interpret their findings as indicative of greater range in limb form and locomotor modes of dinosaurs compared to other archosauromorph groups, and argue that the ability to adopt a wider variety of limb forms and modes might have given dinosaurs a competitive advantage over pseudosuchians.
* A study on the body size evolution of non-avian dinosaurs and Mesozoic birds is published by Wilson et al. (2024), who find no evidence that Bergmann's rule applied to the studied taxa.
* Knoll, Ishikawa & Kawabe (2024) present a new method which can be used to determine the brain volume of extinct archosaurs on the basis their endocranial cavity volume.
* Malafaia et al. (2024) revise fossils from Portugal that were historically assigned to Megalosaurus, and find that the majority of this fossil material represents bones of members of different theropod groups, but also that the studied material includes stegosaurian, iguanodontian, sauropod and thalattosuchian bones.
* Dinosaur and probable crocodylomorph tracks, including some of the largest sauropod tracks worldwide, are described from the Bathonian strata in the El Mers area (Morocco) by Amzil et al. (2024).
* MacLennan et al. (2024) interpret exceptional preservation of fossils (including early birds and feathered non-avian dinosaurs) from the Lower Cretaceous Yixian Formation (China) as unlikely to be linked to violent volcanic eruptions.
