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).[18]

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.[19]
  • 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.[20]
  • A study on the skeletal pathologies affecting known specimens of brachyrostran abelisaurids is published by Baiano et al. (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.[21]
  • Montealegre, Castillo-Visa & Sellés (2024) describe previously unpublished fossil material of theropods (cf. Protathlitis and a carcharodontosaurid which might be distinct from Concavenator) from the Barremian Arcillas de Morella Formation (Spain ).[22]
  • 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.[23]
  • 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.[24]
  • Gianechini, Colli & Makovicky (2024) present a reconstruction of the pelvic and hindlimb musculature of Buitreraptor gonzalezorum.[25]

Sauropodomorph research

  • Agustí, Alcalá & Santos-Cubedo (2024) propose that sauropod gigantism was an adaptation that increased the ability of sauropods to travel great distances, necessitated by pronounced seasonal changes.[26]

Ornithischian research

Thyreophoran research

  • The first stegosaurian fossil material from Gansu (China ), assigned to Stegosaurus sp., is described from the Lower Cretaceous Hekou Group by Li et al. (2024).[27]

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.[28]

  • A study on the limb bone histology and growth dynamics of Musivavis amabilis is published by Kundrát et al. (2024).[32]
  • 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.[33]
  • Acosta Hospitaleche & Jones (2024) describe partial tibiotarsus of a psilopterine phorusrhacid from the Eocene (Lutetian) Sarmiento Formation (Argentina), interpreted as belonging to a bird with an estimated body mass of approximately 5 kg.[34]
