Ichthyosauromorph research
- A study on the skull morphology of Hupehsuchus nanchangensis, based on data from new specimens from the Lower Triassic Jialingjiang Formation (China), is published by Fang et al.

- Kear et al. (2023) describe ichthyopterygian fossil material (including 11 vertebral centra which are substantially larger than those of typical basal ichthyosauriforms) from the Lower Triassic Vikinghøgda Formation (Svalbard, Norway), interpreting the internal structure of the studied bones as indicating that they belonged to a fully pelagic animal, and argue that ichthyosauromorphs might have originated before the Permian–Triassic extinction event.[42]
- Engelschiøn et al.

- Redescription of the holotypes of Grendelius pseudoscythicus and G. zhuravlevi is published by Zverkov, Arkhangelsky & Stenshin (2023), who consider both species to be valid, indicating the presence of at least three species of Grendelius in the Middle Russian Sea during the latest Jurassic, and argue that there is insufficient evidence for synonymy between the genera Brachypterygius and Grendelius.[47]
- Delsett et al. (2023) compare the ossified hyoid elements in ophthalmosaurid ichthyosaurs and toothed whales, and report that, based on hyoid shape, suction feeding seems to never have evolved in ichthyosaurs.[48]

Turtle research
- A study on the body size evolution in turtles is published by Farina et al. (2023), who interpret their findings as indicating that body size was influenced by lineage-specific specializations, such as habitat choice, rather than global trends.[86]

- Purported plant fossils from the Lower Cretaceous Paja Formation (Colombia), originally described as Sphenophyllum colombianum, are reinterpreted by Palma-Castro et al.

(2023), who report that the Plio-Pleistocene fossil record of turtles from the Shungura Formation (Ethiopia) included tortoises which were significantly larger than any extant African taxon, but aquatic turtles did not reach significantly larger maximum sizes than extant eastern African turtles; the authors find the studied fossil record of turtles to be consistent with habitat reconstructions for the Shungura Formation, interpret it as indicating that temperature-dependent metabolism likely wasn't a dominant factor for body size sorting in turtles from the Shungura Formation, and argue that the extinction of the largest eastern African tortoises may have been driven, in part, by human exploitation.[116]
- Revision of the fossil material of Paleogene turtles from Eastern Europe is published by Zvonok & Danilov (2023).[117]

Reptiles in general
- A study on the relationship between femoral microstructure and posture in extant reptiles, and on its implications for the reconstruction of the posture of extinct reptiles, is published by Gônet et al. (2023), who find that the posture can be reliably inferred for extinct reptile taxa that preceded and followed the quadruped/biped and sprawling/erect transitions, but also that the inferences are more questionable for taxa contemporary with these transitions.[162]
- A study on the nasal passage shapes and nasal airflow patterns in extant diapsids, comparing simulated airflow patterns in nasal passages without soft tissues (representing the typical degree of nasal passage preservation in fossils) and with soft tissues, is published by Bourke & Witmer (2023), who interpret their findings as indicating that previous nasal passage reconstructions in extinct species might overestimate airway size, which might affect estimates of physiological capacities of the nasal passages.[163]
- Hoffman, Hancox & Nesbitt (2023) describe an assemblage of teeth of diapsid reptiles from the Lower Triassic Burgersdorp Formation (South Africa), report the presence of seven tooth morphotypes which are distinct but show limited morphological disparity, and interpret this finding as confirming that the recovery of diverse ecosystems after the Permian–Triassic extinction event was delayed until the Middle or even the Late Triassic.[164]
- Zverkov et al. (2023) describe Late Cretaceous reptile fossils from the Pyasina River, Tanama River and Kheta River basins (Siberia, Russia), representing the northernmost Cretaceous Eurasian occurrences of plesiosaurs, turtles and possibly mosasaurids reported to date, and including immature plesiosaur fossils which might indicate that the Late Cretaceous shallow waters in the studied area were a breeding and nursery area for plesiosaurs.[165]
- A study on the competition for prey between Miocene mammalian and reptilian predators at La Venta (Colombia) is published by Wilson & Parker (2023), who interpret their findings as indicative of limited competition for resources among the carnivore guild compared to the most similar extant communities, a dominant role of crocodyliform predators in the studied community, and low predation pressure which might have resulted in overpopulation leading to feeding stress in the notoungulate species Pericotoxodon platignathus.[166]
