TL;DR: A critical review of the recent contributions to iodine‐based, contrast‐enhanced CT research is provided to enable researchers just beginning to employ contrast enhancement to make sense of this complex new landscape of methodologies.

TL;DR: A rare, partial skeleton from the Maastrichtian of Antarctica is identified as the first Cretaceous fossil definitively placed within the extant bird radiation, and phylogenetic analyses supported by independent histological data indicate that a new species, Vegavis iaai, is a part of Anseriformes (waterfowl) and is most closely related to Anatidae, which includes true ducks.

TL;DR: A dinosaur from Mongolia represents the basal divergence within Dromaeosauridae and its small body size and phylogenetic position imply that extreme miniaturization was ancestral for Paraves as discussed by the authors.

TL;DR: Change in theropod body size leading to flight's origin was not unidirectional, and the two dinosaurian lineages most closely related to birds, dromaeosaurids and troodontids, underwent four independent events of gigantism, and in some lineages size increased by nearly three orders of magnitude.

TL;DR: A broad array of morphological characters (including both cranial and postcranial characters) are analyzed for an ingroup densely sampling Neornithes, with crown clade outgroups used to polarize these characters.
