This paper documents previously undescribed appendicular skeletal elements of tyrannosaurid dinosaurs, which were collected in 1917 by Charles H. Sternberg in the Dinosaur Park Formation of Alberta, Canada. In this study, four metatarsals and one pedal phalanx are described and referred to Gorgosaurus libratus, and one pedal phalanx is referred to Daspletosaurus torosus based on several diagnostic characters including the position of the collateral ligament pit, form of the distal articulation surface, and the thickness of the shaft. These specimens are significant because they represent one of the first discoveries of these tyrannosaurids in Alberta, Canada. Lastly, several significant differences between metatarsals of Gorgosaurus and Daspletosaurus, such as the form of the distalmost margin of the third metatarsal as well as the shape of the distal articulation surface of the fourth metatarsal, are recognized.

Fragmentary pterodactyloid remains have been discovered from the Jinju and Hasandong formations (Aptian) in South Korea. Recent studies have suggested that at least some of the dental remains and an isolated second wing phalanx are attributable to the clade Boreopteridae. In this commentary, the author challenges these claims because the teeth considered as Boreopteridae by these authors are clearly distinct from those seen in definite boreopterids, and instead show anhanguerian affinities. The data to support the referral of a fragmentary isolated wing phalanx to Boreopteridae is currently insufficient.
