New dinosaurs include basal sauropodomorph Xingxiulong chengi, sauropod Triunfosaurus leonardii, basal neornithischian Isaberrysaura mollensis, and bird Vanolimicola longihallucis. "Delapparentia" is sunk into Iguanodon.
New studies came out on individual variation and systematics of Iguanodon, the internal anatomy of titanosaur osteoderms, the function of egg shape in Uria aalge, the evolutionary consequences of avian cranial fenestration, and the evolution of passerine nests. Bipedality is argued to have evolved in dinosaurs to facilitate high-speed running. A large sphenisciform is reported from the Waipara Greensand.
