  • Two new furileusaurian abelisaurid specimens from the Santonian Bajo de la Carpa Formation (Argentina), providing new information on the abundance of abelisarids in this area and on variety of abelisaurid morphotypes that coexisted in the north of Argentine Patagonia during the Late Cretaceous, are described by Méndez et al. (2022).[11]

Avian research

  • Description of a new bohaiornithid specimen from the Lower Cretaceous Jiufotang Formation (China), providing new information on the skull anatomy and teeth replacement pattern in bohaiornithids, and a study on the phylogenetic relationships of enantiornithines traditionally included in the family Bohaiornithidae, is published by Liu et al. (2022).[12]

Pterosaur research

  • A study reinterpreting the orbital, antorbital and narial fenestrae in the skulls of the anurognathid pterosaurs, based mainly on data from the skulls of specimens of Batrachognathus volans, and aiming to determine the phylogenetic affinities of anurognathids is published by Dalla Vecchia (2022).[14]
  • A study on the anatomy and phylogenetic affinities of Aerotitan sudamericanus is published by Pêgas et al. (2022), who name the new clades Azhdarchomorpha and Alanqidae.[15]
