 * Yates & Stein (2024) interpret Ultrastenos willisi and "Baru" huberi as synonymous, but maintain Ultrastenos as a distinct mekosuchine genus, resulting in a new combination Ultrastenos huberi.
 * 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.
 * 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 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.

 * Mohabey et al. (2024) review and redescribe Laevisuchus indicus, Jubbulpuria tenuis and Compsosuchus solus, and describe a new noasaurid dentary from central India with procumbent dentition similar to the one present in Masiakasaurus.

 * Park et al. (2024) propose that early pennaraptorans might have used their pennaceous feathers to flush hiding insects and to generate lift or drag during the pursuit of the flushed insects, and propose that such use of the pennaceous feathers might have contributed to the evolution of larger and stiffer feathers.
 * A characterization of how number and shape of flight feathers correlate with locomotory style in extant birds is published by Kiat & O'Connor (2024). Extrapolating these patterns to Mesozoic pennaraptorans, the authors suggest that Caudipteryx and anchiornithines may have been secondarily flightless.

 * Description of the skeletal anatomy of Oksoko avarsan is published by Funston (2024).
 * Zhu, Wang & Wang (2024) study the microstructural variation of elongatoolithid eggs from China, and interpret the studied variation as indicating that not all elongatoolithid eggshells can be related to oviraptorosaurs.
 * A study on the skull shape and bite mechanics of dromaeosaurids is published by Tse, Miller & Pittman (2024), who interpret Deinonychus antirrhopus as adapted to taking large vertebrate prey, and interpret Halszkaraptor escuilliei as unlikely to feed on fish, and more likely to have a feeding ecology similar to those of extant waterfowl.
 * Possible dromaeosaurid eggs are described from the Upper Cretaceous Lianhe Formation (China) by Wu et al. (2024), who name a new ootaxon Gannanoolithus yingliangi, and interpret the discovery of paired eggs of Gannanoolithus as possible evidence that dromaeosaurids had paired functional oviducts.

 * Nikolov, Dochev, & Brusatte (2024) test the ontogenetic age of small hadrosauroid bones from the Late Cretaceous (Maastrichtian) Kaylaka Formation (Bulgaria), and determine that the specimen likely belonged to a late juvenile or young subadult, rather than a dwarved adult, and suggest that large terrestrial animals were able to populate some European islands via a cyclically appearing or short-lived dispersal route.
 * The first described hadrosaurid footprints from the Horseshoe Canyon Formation are described by Powers et al. (2024), who assign them to the ichnospecies Hadrosauropodus langstoni.

(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.

(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.
 * A study aiming to determine the diets of members of the family Bohaiornithidae is published by Miller et al.

(2024).
 * A study on the evolutionary history of neoavians, as indicated by genomic data, is published by Wu et al.

(2015) about the paleobiology of fossil penguins to be properly supported by their data.

 * 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.

Pterosaur research

 * A study on the cervical osteology of Anhanguera piscator, Azhdarcho lancicollis and Rhamphorhynchus muensteri, aiming to reconstruct the cervical arthrology of pterosaurs and the position of the pterosaur neck at rest, is published by Buchmann & Rodrigues (2024).
 * A study on the palate structure in Kunpengopterus, Hongshanopterus, Hamipterus and Dsungaripterus, providing new information on the relations between the palatine, ectopterygoid, maxilla and pterygoid in the studied pterosaurs resulting in reinterpretation of the main palatal openings, and identifying an opening bordered anteriorly by the maxilla and posteriorly by the palatine that is unique within Diapsida and might be a synapomorphy of Pterosauria, is published by Chen et al. (2024).

 * 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.

General research

 * A study on the evolution of locomotion in archosauromorph reptiles is published by Shipley et al.
