New dinosaurs include oviraptorosaur Apatoraptor pennatus and sauropod Sarmientosaurus musacchioi.
New studies came out on brain activity during flight in Sturnus vulgaris, the evolutionary history of titanosaurs, dental histology of Coelophysis bauri, the genetic basis for beak size in geospizines, skeletal kinematics of avian limbs during development, the histology of craniofacial sutures in dinosaurs, the history of Australian sphenisciforms, and the reproductive biology of Sapayoa aenigma. Amargatitanis macni is reevaluated and found to be a dicraeosaurid, whereas Willinakaqe salitralensis is reevaluated as non-diagnostic. Island birds are found to predictably evolve decreased flight ability. Ceratopipra mentalis and Manacus vitellinus are found to have superfast forelimb muscle contractile speed used in social display. A juvenile specimen of Rapetosaurus krausei, a specimen of Psittacosaurus with a healed fibular fracture, an enantiornithine preserved with a pellet containing fish bones, and the anatomy of Eotrachodon orientalis are described. Elaphrosaurus bambergi and the skull of Tapuiasaurus macedoi are redescribed.
