Abstract Hadrosaurid dinosaurs are abundantly represented in terrestrial deposits from the Late Cretaceous, as isolated elements, associated specimens, and articulated skeletons with soft tissue. However, identifi cation of isolated elements can be diffi cult in the absence of adequate reference material. Here we present a photographic atlas of the complete pes from a hadrosaurine hadrosaurid (possibly Edmontosaurus annectens) collected in the Hell Creek Formation of Montana.

Abstract Skin impressions from hadrosaurid dinosaurs are relatively common finds throughout the Cretaceous Western Interior of North America. A recently discovered specimen from the late Campanian-aged Kaiparowits Formation of southern Utah is typical for hadrosaurs, with randomly arranged polygonal tubercles averaging around 4 mm in length and 3 mm in width. Based on the associated bones, these impressions likely originated on the thorax of the animal. In contrast with most previously published finds, the skin is not preserved in perfect articulation with the skeleton. This suggests a taphonomic mode in which the skeleton and soft tissues were partially disarticulated prior to burial.
