New dinosaurs include sauropod Wamweracaudia keranjei and avialans Zygodactylus ochlurus, Conflicto antarcticus, and Shangyang graciles.
New studies came out on the cranial osteology of Beipiaosaurus inexpectus, the molecular evolution of maniraptor feathers, the diversification of trogonids, and the role of female feedback in song learning by Taeniopygia guttata. Corvus moneduloides are found to be able to infer weight of objects from their movements in a breeze. Female Melopsittacus undulatus are shown to prefer problem-solving males. Sauropodomorphs are suggested to be the trackmakers of Eubrontes tracks. A feathered enantiornithine foot preserved in amber and new specimens of Pachyrhinosaurus perotorum are described. Photoluminescence in the bills of Fratercula arctica is reported.
