If you love abstract photography, urban scenes, and architecture then this photo 2023 calendar has it all. An isolated spinosaurid tooth of uncertain provenance, likely recovered from a Valanginian exposure of the Hastings Group ( United Kingdom), is assigned to a taxon distinct from Baryonyx walkeri by Barker, Naish& Gostling (2023). [108] A study on the bone histology of the holotype of Liaoningvenator curriei is published by Martin, Caizhi & Kundrát (2023), who interpret their findings as indicative of a growth pattern transitive between those of basalmost and more derived troodontids. [147] A study on the gastral mass preserved with specimens of Archaeorhynchus and Iteravis, interpreted as indicative of the digestive system comparable to that of extant birds, is Liu et al. (2023).

A study aiming to determine the diets of members of the family Bohaiornithidae is published by Miller et al. (2023), who interpret their findings as indicating that the family included taxa adapted to diverse diets, and predict the ancestral member of Enantiornithes to have been a generalist which ate a wide variety of foods.

Galton (2023) describes a right sternal bone of a specimen of Stegosaurus from the Carnegie Quarry at Dinosaur National Monument ( Morrison Formation; Utah, United States) and reevaluates three putative sternal bones from Como Bluff ( Wyoming, United States) described by Gilmore (1914), [184] arguing that they are neither sternal bones nor fossils of Stegosaurus.

Smith & Gillette (2023) reconstruct soft tissues of the hindlimbs and likely posture of Nothronychus graffami. [134] Macaulay et al. (2023) report that, in spite of the differences of body shape, there is overall no difference in the position of whole-body centre-of-mass between birds and non-avian theropods, but rather that there is such difference between hindlimb-dominated predominantly terrestrial taxa and forelimb-dominated predominantly volant taxa regardless of their phylogenetic placement, and argue that the fully crouched bipedalism seen in modern birds evolved after powered flight. [239] A collection of seven isolated spinosaurid teeth as well as a single preungual pedal phalanx of an indeterminate theropod are reported from the Berriasian–Valanginian Feliz Deserto Formation (Brazil) by Lacerda et al. (2023). [45] Zelenkov & Arkhangelsky (2023) describe new fossil material of Campanian hesperornithids from the Karyakino locality ( Saratov Oblast, Russia), including the first femur of Hesperornis rossicus.

A study comparing dentin and enamel microstructure in Microraptor, Anchiornis, Sapeornis and Longipteryx, providing evidence of microscopic modifications in tooth enamel, dentin and cementum between early birds and other theropods, as well as previously unrecognized plasticity in the developmental mechanisms controlling tooth microstructure in Mesozoic toothed birds, is published by Wang et al.

A study on the taxonomic diversity, phylogenetic relationships and evolutionary history of Australasian crocodyliforms is published by Ristevski et al. (2023). [37] A collection of 55 coprolites from the Eocene Na Duong Basin ( Vietnam) are described by Halaçlar et al.
