New dinosaurs include dromaeosaurid Changyuraptor yangi, hadrosaur Augustynolophus morrisi (formerly a species of Saurolophus), birds Bambolinetta lignitifila (formerly a species of Anas) and Pelagornis sandersi, and the fuzzy basal neornithischian Kulindadromeus zabaikalicus. "Chenornis" is sunk as a species of Plotornis.
A new specimen of Archaeopteryx with well-preserved integument, the first trackways of tyrannosaurids (representing multiple individuals), and new material of Itemirus medullaris are described. New studies came out on the phylogenetic position of Caloenas maculata, the forelimb myology of Tawa hallae, the neuroanatomy of Amargasaurus cazaui, the taphonomy of North American pachycephalosaurs (showing that they probably weren't mountain-dwelling animals), the detailed anatomical change through ontogeny in Gallus gallus domesticus, the wing efficacy of trochilids, the vocal repertoire of Spheniscus demersus. The first Mexican remains of Ichthyornis dispar are reported. The causes of dinosaur extinction at the end of the Cretaceous are reviewed.
