New dinosaurs include ceratosaur Chenanisaurus barbaricus, basal(?) theropod Shuangbaisaurus anlongbaoensis, birds Scytalopus alvarezlopezi and Opisthodactylus kirchneri, and tyrannosaurid Daspletosaurus horneri (which has generated much discussion for its inferred facial soft tissue).
New studies came out on resolving conflicts in neornithine phylogeny, craniofacial diversification in Columba livia domestica, jaw function in therizinosaurs, scaling of strigiform hind limbs, pectoral girdle morphology of Mesozoic avialans, and mandibular anatomy of Lesothosaurus diagnosticus. Previous inferences of sexual dimorphism in non-avian dinosaurs are found to be statistically poorly supported. Sociality is found to be correlated with reduced brain size in picids. Nestor notabilis is shown to have a distinct play vocalization that serves as a positive emotional contagion (similar to a laugh). Preservation of tendons/ligaments and cartilage
