(2022), who interpret their findings as indicative of deeper osteoderm implantation within the dermis in Iberosuchus than in other studied taxa, as well as indicative of the loss of ornamentation of osteoderms in derived notosuchians, which might be linked to their terrestrial lifestyle and specific thermoregulation strategy. A study on the evolution of palatal anatomy in early crocodylomorphs is published by Dollman & Choiniere (2022). An ilium of an early diverging crocodylomorph is described from the Upper Triassic Otis Chalk assemblage (Colorado City Formation, Dockum Group; Texas, United States) by To, Nesbitt, Stocker (2022), expanding the knowledge of the distribution of early crocodylomorphs during the Late Triassic.

(2022), who interpret their findings as indicating that Araripesuchus wegeneri, Armadillosuchus arrudai, Baurusuchus, Iberosuchus macrodon and Stratiotosuchus maxhechti were ectothermic. A study on the osteoderm histology of Cretaceous notosuchians from Brazil is published by Sena et al. (2022), who report evidence of Sharpey's fibres in Armadillosuchus arrudai, Itasuchus jesuinoi and baurusuchids interpreted as indicative of the presence of thick leathery layer of skin overlying osteoderms, and report the presence of the vascular canals in some sampled osteoderms which might have increased the capacity of heat transfer. Description of the microstructure of the tooth and tooth attachment tissues of Notosuchus terrestris is published by Navarro et al. (2022), who find the relative and absolute enamel thickness of N. terrestris to be similar to those reported for carnivorous notosuchians such as baurusuchids, and interpret their findings as indicating that the tooth growth rates of N. terrestris were reduced in comparison with other notosuchians. A study on the bone histology of Mariliasuchus amarali, based on a new specimen is published by Sena et al. (2022).

Fossil material of an Early Jurassic teleosauroid crocodylomorph is described from the Chaara cave (Morocco) by Hicham et al. (2022), representing the oldest African thalattosuchian reported to date, and indicating that thalattosuchians were widely distributed as soon as the earliest Jurassic. Serafini et al. (2022) describe a clustered mass of bones of an aeolodontine teleosaurid from the Upper Jurassic Rosso Ammonitico Veronese Formation (Italy) interpreted as a regurgitalite, representing the first crocodylomorph described in a regurgitalite and expanding known geographic range of aeolodontines. Le Mort et al. (2022) describe a specimen of Metriorhynchus (with affinities to M. superciliosus) from the Middle Jurassic (Callovian) of Vaches-Noires cliffs (Normandy, France), report the presence of diagnostic criteria of different metriorhynchids in the skeleton of this specimen, and evaluate the implications of this specimen for the knowledge of the taxonomic value of the criteria used to distinguish between the different Callovian and Oxfordian metriorhynchid species.

Crocodylomorph eggshell fragments, probably representing remains of eggs produced by allodaposuchids, are described from the Maastrichtian of the Southern Pyrenees (Huesca, Spain) by Moreno-Azanza et al.

Kuzmin (2022) reviews all known material of long-snouted crocodyliforms from the Upper Cretaceous (Cenomanian–Santonian) of Central Asia, confirms Zholsuchus procerus to be a valid taxon, and argues that it is likely one of the oldest known members of the crown group of Crocodylia. Redescription of the holotype of Notocaiman stromeri, and a study on its taxonomic status and phylogenetic affinities, is published by Bona et al. (2022). A study aiming to estimate the body size of large caimanines from the Miocene of South America, including Purussaurus and Mourasuchus, is published by Paiva et al. (2022). Pessoa-Lima et al.
