Spiekman, S. N. F. (2023). "A revision and histological investigation of Saltoposuchus connectens (Archosauria: Crocodylomorpha) from the Norian (Late Triassic) of south-western Germany". Zoological Journal of the Linnean Society. 199 (2): 354–391. doi: 10.1093/zoolinnean/zlad035. A study on the stable oxygen and carbon isotope compositions of dinosaur eggshell calcites and tooth apatites from the Upper Cretaceous Kakanaut Formation ( Chukotka Autonomous Okrug, Russia) is published by Amiot et al. (2023), who interpret their findings as indicating that near-polar Kakanaut dinosaurs likely laid eggs in early spring, giving time for the hatchlings to grow before winter. [84] Stidham, O'Connor & Li (2023) reexamine the holotype of Corvus fangshannus and reinterpret it as a member of the sedentary Northern Raven ( Corvus corax) lineage. [280] A study on the endocranial morphology of Liaoceratops yanzigouensis is published by Yang et al. (2023), who find that the brain, olfactory bulb and inner ear of Liaoceratops more closely resemble those observed in Psittacosaurus than those in more derived ceratopsians. [203] Joubarne, Therrien & Zelenitsky (2023) describe extensive skin impressions in three hadrosaurid specimens from the Campanian Dinosaur Park Formation ( Alberta, Canada), with two specimens preserving integument of the manus showing that their digits II–III–IV were approximately equal in length and united in a common fleshy structure, and the third specimen preserving scale stripes on its torso which might have corresponded to color stripes in life. [197]Zelenkov & Arkhangelsky (2023) describe new fossil material of Campanian hesperornithids from the Karyakino locality ( Saratov Oblast, Russia), including the first femur of Hesperornis rossicus. [252] Aureliano et al. (2023) present the criteria which can be used to distinguish between lamellar bone fibres, Sharpey's fibres (tendon insertions) and air sac attachments in the bones of fossil archosaurs. [316]

Taborda, J. R. A.; Von Baczko, M. B.; Desojo, J. B. (2023). "Biomechanical analysis and new trophic hypothesis for Riojasuchus tenuisceps, a bizarre-snouted Late Triassic pseudosuchian from Argentina". Acta Palaeontologica Polonica. 68 (3): 415–425. doi: 10.4202/app.01038.2022. S2CID 261551160. A study on the bone histology of Stratiotosuchus maxhechti, interpreted as indicative of growth dynamics similar to those of medium-to-large theropods, is published by Andrade et al. (2023), who argue that niche partitioning between baurusuchids and theropods was more likely than competitive exclusion. [30]Description of the skull osteology of Manidens condorensis is published by Becerra et al. (2023). [181]
