LeBlanc et al. (2024) report that extant Komodo dragons maintain cutting edges of their teeth through iron-enriched coatings on their tooth serrations and tips, argue that iron sequestration is probably widespread in reptile enamels, but also find no evidence of iron coatings along theropod dinosaur tooth serrations, report that tyrannosaurids had specialized, wavy enamel along their tooth serrations that likely supported the cutting edges of the teeth, and interpret these findings as either indicative of different feeding strategies of tyrannosaurids and Komodo dragons, or indicating that only large theropods had tooth enamel that was thick enough to significantly influence the mechanical wear of the tooth serrations.^[123]
Słowiak, Brusatte & Szczygielski (2024) reevaluate the fossil material attributed to Bagaraatan ostromi, interpreting the holotype as an indeterminate juvenile tyrannosaurid, and reporting that some of the fossils originally attributed to B. ostromi are actually caenagnathid bones.^[124]

Mallon & Hone (2024) estimate that past sampling efforts likely resulted in sampling even the 99th percentile of body mass reached by Tyrannosaurus rex, and that the very largest members of the species might have been up to 70% larger than the largest currently known specimens, reaching approximately 15,000 (± 3750) kg of body mass.^[129]

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.^[223]

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.^[229]
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.^[230]
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.^[231]

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.^[236]
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.^[237]
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.^[238]
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.^[239]
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.^[240]

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).^[243]
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.^[244]
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.^[245]
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.^[246]

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)^[252] and Ksepka et al. (2015)^[253] about the paleobiology of fossil penguins to be properly supported by their data.^[254]

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).^[271]
A study aiming to determine the aerodynamic impact of large heads and head crests of pterosaurs is published by Henderson (2024).^[272]

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.^[274]
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.^[275]
