Modern birds are typified by the presence of feathers, complex evolutionary innovations that
were already widespread in the group of theropod dinosaurs (Maniraptoriformes) that …

The most commonly preserved soft tissues associated with ornithischian dinosaurs are skin
remains. The apparent resistance of hadrosaur skin to decay, and its abundance in the fossil …

Spectacularly preserved non-avian dinosaurs with integumentary filaments/feathers have
revolutionized dinosaur studies and fostered the suggestion that the dinosaur common …

Recent discoveries in Asia have greatly increased our understanding of the evolution of
dinosaurs' integumentary structures, revealing a previously unexpected diversity of …

Ankylosaurian dinosaurs are most notable for their abundant and morphologically diverse
osteoderms, which would have given them a spiky appearance in life. Isolated osteoderms …

Discovered in 1852, the scaly skin belonging to Haestasaurus becklesii was the first to be
described in any non-avian dinosaur. Accordingly, it has played a crucial role in the …

Examination of preserved skin from a duckbill dinosaur revealed disruption of the normal
scale pattern and replacement by granulation tissue. Wrinkles radiating outward from the …

The characterization of palaeospecies typically relies on hard-tissue anatomy, such as
bones or teeth that is more readily fossilized than soft parts. Among dinosaurs, skin …

Skin impressions from the tail region of an indeterminate hadrosaur recently excavated from
the Upper Cretaceous Ringbone Formation, southwest New Mexico represent the first …

The origin of birds and avian flight from within the archosaurian radiation has been among
the most contentious issues in paleobiology. Although there is general agreement that birds …
