General non-avian dinosaur research
- 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).[12]
Saurischian research
Theropod research
- A study on the affinities of isolated theropod teeth from the Bauru Basin (Brazil) is published by Delcourt et al. (2024), who argue that the geographical distribution of abelisaurids in South America was influenced by climatic conditions.[13]
- A study in the bone histology of a mid-sized abelisaurid from the Upper Cretaceous Serra da Galga Formation (Brazil) is published by Aureliano et al. (2024), who report that, despite living in a semiarid tropical environment, the studied specimen had a growth rate similar to those of the Patagonian abelisaurids.[14]
- Longrich & Saitta (2024) review the taxonomic status of Nanotyrannus and argue that multiple lines of evidence support it as a distinct, small-bodied, possibly non-tyrannosaurid taxon, rather than an immature form of Tyrannosaurus.[15]
- Gianechini, Colli & Makovicky (2024) present a reconstruction of the pelvic and hindlimb musculature of Buitreraptor gonzalezorum.[16]
Sauropodomorph research
Ornithischian research
Thyreophoran research
Cerapod research
- 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.[17]

Avian research
- A morphometric study of a large sample of specimens of Confuciusornis sanctus is published by Zhou et al. (2024), who intepret their findings as indicative of the presence of sexual dimorphism in this species.[19]
- 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.[20]
