[156] Young et al. (2023) describe thalattosuchian fossil material from deposits in European Russia ranging from Bajocian to Berriasian or Valanginian in age, including fossil material of cf. Thalattosuchus, Torvoneustes and Tyrannoneustes which expands known geographical range of these taxa, as well as including the oldest record of Geosaurini reported to date.

It’s great to print the 2023 calendars month by month. You have enough space to write down what you want to do that day or important dates or events you have that month. You will have everything under control. Darlim, G.; Suraprasit, K.; Chaimanee, Y.; Tian, P.; Yamee, C.; Rugbumrung, M.; Kaweera, A.; Rabi, M. (2023). "An extinct deep-snouted Alligator species from the Quaternary of Thailand and comments on the evolution of crushing dentition in alligatorids". Scientific Reports. 13 (1). 10406. Bibcode: 2023NatSR..1310406D. doi: 10.1038/s41598-023-36559-6. PMC 10344928. PMID 37443318. A tooth of a member of the genus Purussaurus is described from the Toma Vieja locality near Paraná City (traditionally considered as the base of Ituzaingó Formation) by Bona et al. (2023), representing the first record of this genus from the Late Miocene of Argentina and the southernmost occurrence of a member of this genus reported to date. [39] The holotype of Mamenchisaurus sinocanadorum is redescribed by Moore et al. (2023), who also interpret Bellusaurus and Daanosaurus as juvenile mamenchisaurids. [160] Ecomorphology of the penguin wing is studied by Haidr (2023), finding that Madrynornis resembled extant piscivorous penguins in its wing morphology. [270]Wu et al. (2023) study the phytoliths preserved in the stomach contents of a specimen of Jeholornis prima, interpreting them as indicating that Jeholornis likely ate leaves of plants from the magnoliid angiosperm clade. [242] An egg belonging to a flamingo from the Pleistocene of Mexico is described by Cruz et al. (2023). [267] A juvenile sauropod specimen, most closely resembling early-diverging eusauropods from the Middle Jurassic but sharing some derived features with the Late Jurassic mamenchisaurids and neosauropods, is described from the Middle Jurassic Dongdaqiao Formation (East Tibet, China) by An et al. (2023). [159]

Theropod scrapes from the Cretaceous of Colorado, originally interpreted as evidence of display arenas or leks of theropods, [99] are argued to be more likely results of failed attempts by theropods to dig near-circular bowls that were to be used as nests by Moklestad & Lucas (2023). [100] A member of the family Tapejaridae. The type species is "Huaxiapterus" corollatus Lü et al. (2006). Venczel (2023) describes new fossil material of Diplocynodon kochi from the Eocene Transylvanian Basin ( Romania), extending known fossil record of this species to four new localities. [38] A study on the hindlimb variation between the best-preserved specimens of putative ornithomimosaurs from the Angeac-Charente bonebed ( France) is published by Pintore et al. (2023), who interpret their findings as indicative of the presence of sexual dimorphism in the studied theropods. [128]Tumanova et al. (2023) describe anomalies within the airway and sinuses of a skull of a specimen of Tarchia, which were only detected while CT scanning the specimen, and which might have been caused by infection and/or trauma.

[250] A study on the anatomy of the articular region of the lower jaw of Vegavis iaai is published by Álvarez-Herrera et al. (2023), who report the presence of anatomical features shared with neornithine birds, and particularly with members of the neoavian clade Aequorlitornithes. [254] Lehane, J. R. (2023).

[206] Putative avialan teeth from the Late Cretaceous of Alberta, Canada are reinterpreted as belonging to crocodylians by Mohr, Acorn & Currie (2023). [322] Jagielska et al.
