Parasaurolophus walkeri restoration,

• Images of Parasaurolophus skulls were used as reference.

• Skin impressions are known in Parasaruolophus. It's known to had 'tubercilated' skin similar to other hadrosaurs. (Parks 1922, Parasaruolophus Walkeri, A new Genus of crested Trachont Dinosaur.) (Farke et al. 2013 Ontogeny in the tube-crested dinosaur Parasaurolophus (Hadrosauridae) and heterochrony in hadrosaurids.)

Known Parasaurolophus skin impressions aren't extensive and don't show all the details. Some of the skin details shown here are speculative but based on those described for another hadrosaur fossil that preserves more extensive skin impressions. ^[1]

The frill running down the top of the back is not known in Parasaurolophus. Frills/dermal ridges are known in a few hadrosarus. The one shown here is based loosely on the close relative Corythosaurus (Kennith Karpenter, 1999, Eggs, Nests, and Baby Dinosaurs, A Look at Dinosaur Reproduction.)

• The colours and/or patterns, as with most restorations of prehistoric creatures, are speculative.
