New dinosaurs include ornithomimosaur Tototlmimus packardensis and dromaeosaurid Dakotaraptor steini.
New studies came out on the life history of Maiasaura peeblesorum, the evolution of avian wing shape, the ultrastructure of theropod teeth and anseriform herbivory, the phylogeny of neornithines, thermophysiology in titanosaurs and oviraptorids, the nesting behavior of titanosaurs, and the density and function of Aptenodytes forsteri feathers. An enantiornithine wing preserving soft tissues, perinatal specimens of Saurolophus angustirostris, the postcranial skeleton of Stegosaurus stenops, a specimen of Ornithomimus with preserved feathers, and a titanosaur braincase are described. Sigilmassasaurus brevicollis is redescribed. Histological evidence for a supraspinous ligament in sauropods is reported.
