New dinosaurs include coelophysoid Lucianovenator bonoi, ankylosaur Zuul crurivastator, troodonts Liaoningvenator curriei and Jianianhualong tengi, sauropods Galeamopus pabsti and Vouivria damparisensis, oviraptorosaur Beibeilong sinensis, and bird Campylopterus calcirupicola.
New studies came out on the minimization of energetic cost during foraging flight in Forpus coelestis, the biomechanics of bone-eating in Tyrannosaurus rex, the evolution of craniodental function in sauropodomorphs and beak shape in anseriforms, the extent of the caudofemoralis longus muscle in Allosaurus fragilis, the phylogenetic position of Nipponosaurus sachalinensis, and underwater hearing in Phalacrocorax carbo. New specimens of Eolambia caroljonesa and Camarasaurus are described. Sexual dimorphism is suggested to be hard to identify in non-avian dinosaurs due to their protracted period of growth. Phoenicopterids are shown to use little active muscular force while standing on one leg. Purported peptide sequences discovered in Cretaceous dinosaurs are found to be indistinguishable from some potential modern contaminants (such as Struthio camelus collagen). Tawa hallae is argued to not represent a growth stage of Dromomeron romeri. Safekeeping of tools is reported in Cacatua goffiniana, as is the use of mud by Neophron percnopterus for cosmetic purposes.
