New dinosaurs include hadrosaur Zhanghenglong yangchengensis. Spizella arborea is split into the new genus Spizelloides. Dicaeum kuehni is split from Dicaeum celebicum.
"Saurornitholestes" robustus is reevaluated as a troodont. Juvenile specimens of Edmontosaurus annectens and Megaraptor namunhuaiquii are described. New studies were published on aerial ability in basal paravians, evolutionary trends in Triceratops, the origins of carotenoid-pigmented feathers and zygodactyl feet, evidence for mesothermy in dinosaurs, theropod diversity in the Aptian-Albian of Tunisia, limb musculature of accipitriforms, the evolution of elaborate signals in thraupids, and the anatomy and phylogenetic position of Aragosaurus ischiaticus.
