 Aside from those found on Corythosaurus casuarius , extensive skin impressions have been found on Edmontosaurus annectens and notable integument has also been found on Brachylophosaurus canadensis , Gryposaurus notabilis , Parasaurolophus walkeri , Lambeosaurus magnicristatus , L. lambei , Saurolophus angustirsotris and on unidentified ornithopods . Of these , L. lambei , C. casuarius , G. notabilis , P. walkeri , and S. angustirsotris have preserved polygonal scales . The scales on L. lambei , S. angustirostris and C. casuarius are all similar . Corythosaurus is one of very few hadrosaurids which have preserved skin impressions on the hind limbs and feet . A study in 2013 showed that amongst hadrosaurids , Saurolophus angustirostris preserved the best and most complete foot and limb integument , although other species like S. osborni , Edmontosaurus annectens and Lambeosaurus lambei ( = L. clavinitialis ) share a fair amount of preserved tissue on those regions .
