This article records new taxa of every kind of fossil archosaur that are scheduled to be described during 2023, as well as other significant discoveries and events related to the paleontology of archosaurs that will be published in 2023.

General pseudosuchian research
Aetosaur research
Crocodylomorph research
- Evidence from the osteological correlates of the trigeminal nerve in extant and fossil taxa, interpreted as indicative of an increase in sensory abilities in Early Jurassic crocodylomorphs, preceding their transitions to a semiaquatic habitat, is presented by Lessner et al. (2023).[2]
- Description of new fossil material of itasuchid crocodyliforms from the Upper Cretaceous Bauru Group (Brazil) is published by Pinheiro et al. (2023), who also confirm the monophyly of Itasuchidae with some variation in its content, and find the South American itasuchid species to occupy a crocodyliform morphospace, possibly indicating distinct niche occupations.[3]
- A collection of isolated gavialoid teeth is reported from the shallow marine deposits of Eocene Turnu Roșu (Romania) by Venczel et al. (2023), who recognize a minimum of five morphotypes.[4]
- A collection of eighteen isolated neosuchian teeth as well as a single isolated crocodyliform osteoderm are reported from the Berriasian–Valanginian Feliz Deserto Formation (Brazil) by Lacerda et al. (2023), who recognize a minimum of three morphotypes among the teeth.[5]

Late Cretaceous (Campanian) |

General non-avian dinosaur research
- Cullen et al. (2023) reevaluate evidence for anomalously positive stable carbon isotope compositions of dinosaur bioapatite, report that the studied anomaly is present in the carbon isotope compositions of bioapatite in tooth enamel of not only dinosaurs but also mammals and crocodilians and in scale ganoine of gars from the "Rainy Day Site" in the Campanian Oldman Formation (Alberta, Canada) but is absent in extant vertebrates from the near-analogue modern ecosystem in the Atchafalaya Basin (Louisiana, United States), and interpret their findings as indicating that the studied anomaly is not the result of a unique dietary physiology of dinosaurs.[7]
- Dinosaur eggshell fragments with preserved eggshell membranes are reported from the Late Jurassic Brushy Basin Member of the Morrison Formation (Utah, United States) by Lazer et al. (2023).[8]
Saurischian research
- A tracksite of dinosaur footprints is described from the Middle Jurassic Xietan Formation (Hubei, China) by Xing et al. (2023), who interpret the tracks as belonging to small sauropods (similiar to Brontopodus) and probable theropods.[9]
Theropod research
- A study on the relationship between the body size of theropods, the area of muscles important for their balance and locomotion, and their capacity for agility is published by Henderson (2023), who argues that theropod body plan had an upper size limit based on a minimum acceleration threshold.[10]
- Sharma, Hendrickx & Singh (2023) describe dental material of a non-coelurosaur averostran theropod from the Bathonian Fort Member of the Jaisalmer Formation (India), providing evidence of the presence of at least one taxon of a medium to large-bodied theropod on the Tethyan coast of India during the Middle Jurassic.[11]
- A collection of seven isolated spinosaurid teeth as well as a single preungual pedal phalanx of an indetermined theropod are reported from the Berriasian–Valanginian Feliz Deserto Formation (Brazil) by Lacerda et al. (2023).[5]
- Reconstruction of the musculature of the pectoral girdle and forelimbs in megaraptoran theropods is presented by Aranciaga Rolando et al. (2023).[12]
- A pathological third metatarsal of Phuwiangvenator, indicating that the bone experienced a greenstick fracture and healed before the animal's death, is described from the Lower Cretaceous Sao Khua Formation (Khon Kaen, Thailand) by Samathi et al. (2023).[13]
- A study estimating the number of telencephalic neurons in theropod dinosaurs is published by Herculano-Houzel (2023), who argues that Allosaurus and Tyrannosaurus are endotherms with baboon- and monkey-like numbers of neurons;[14] however, this study has been criticized.[15]
- A partial left tibia and articulated proximal tarsals, likely belonging to an indeterminate velociraptorine, are described from the Upper Cretaceous Lo Hueco fossil site (Cuenca, Spain) by Malafaia et al. (2023), who also review the European theropods of the Late Cretaceous.[16]
Sauropodomorph research
- Lockley et al. (2023) evaluate a number of trackways assigned to basal saurischians, including those belonging to the ichnogenera Otozoum, Pseudotetrasauropus, Evazoum, and Kalosauropus, and examine their implications on the gait of "prosauropods".[17]
- Cervical vertebra representing the first record of a titanosauriform sauropod from the Lower Cretaceous Kanmon Group (Japan) is described by Tatehata, Mukunoki & Tanoue (2023).[18]
- Dhiman et al. (2023) report the discovery of 92 titanosaur egg clutches from the Upper Cretaceous Lameta Formation (Madhya Pradesh, India), including three types of clutches and assigned to six oospecies, interpret their findings as suggestive of higher diversity of titanosaur taxa from the Lameta Formation than indicated by body fossils, and evaluate the implications of the studied egg clutches for the knowledge of the reproductive biology of titanosaurs.[19]
Ornithischian research
- A study on the biomechanical properties of the skulls of Heterodontosaurus tucki, Lesothosaurus diagnosticus, Scelidosaurus harrisonii, Hypsilophodon foxii and Psittacosaurus lujiatunensis is published by Button et al. (2023), who interpret their findings as indicative of limited functional convergence among studied taxa, which achieved comparable performance of the feeding apparatus through different adaptations.[20]
- Review of the fossil record of ornithischian dinosaurs from Southeast Asia and southern China is published by Manitkoon et al. (2023)[21]
Thyreophoran research
- 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),[22] arguing that they are neither sternal bones nor fossils of Stegosaurus.[23]
Cerapod research
- Redescription of Cumnoria prestwichii is published by Maidment et al. (2023), who recover Cumnoria as a non-ankylopollexian iguanodontian, and consider it to be distinct from Camptosaurus.[24]
- García-Cobeña, Cobosa & Verdú (2023) describe bone and trace fossils of styracosternan ornithopods from the Lower Cretaceous El Castellar Formation and Camarillas Formation (Spain), including manus-pes track set from the Camarillas Formation indicative of quadrupedal locomotion, assigned to the ichnogenus Caririchnium and produced by large styracosternans related to Iguanodon.[25]

Avian research

General research
- Wang, Claessens & Sullivan (2023) establish skeletal features associated with the attachment of uncinate processes to vertebral ribs in extant birds and crocodilians, attempt to determine their distribution in fossil archosaurs, and interpret their findings as indicating that cartilaginous uncinate processes were plesiomorphically present (and likely had a ventilatory function) in dinosaurs, and maybe even in archosaurs in general.[32]
