Epiderma je bila tanka, a krljušti su bile malene i nisu se preklapale,<ref name=HFO09/> kao i kod guštera ''[[Heloderma suspectum]]''.<ref name=LW42d/> Na većem dijelu tijela postojala su dva tipa krljušti: malene zašiljene ili konveksne tuberkule, 1 do 3 mm u promjeru bez nekog određenog rasporeda; i veće, ravne mnogokutne tuberkule, obično promjera manjeg od 5 mm, ali i to 10 mm na području podlaktice. Ove zadnje su se grupirale u hrpegrupe koje suje odjeljivaliprvi jednetip odkrljušti drugihodjeljivao prvijedne tipod krljuštidrugih; na prijelazu između velikih u male krljušti postojao je tranzicijski tip krljušti. Na većem dijelu tijela su veće krljušti bile raspoređene u kružne ili ovalne hrpegrupe, a blizu ramena na ruci formirale su pruge gotovo paralelne jedne drugima. Sve u svemu, hrpegrupe su bile veće na gornjem dijelu tijela, a manje na donjem. Iznad kukovlja su postojale hrpegrupe dužine 50 cm.<ref name=HFO12/>

Jedini otisci kože sa glave dolaze od velikih otvora za nosnice. Umjesto otisaka tuberkula, tu su se nalazili otisci mekog tkiva, sa dubljim dijelom dalje nazad, što su mogle biti nosnice.<ref name=LW42d/> Vrat i leđa imali su mekan greben ili nabor po sredini, sa redom ovalnih grupa tuberkula iznad šiljastih nastavaka kralježaka. Točna visina grebena kod primjerka AMNH&nbsp;5060 nije poznata, a ni mjesto njegove gornje granice, budući da je nedostajao gornji dio. Greben je bio visok barem 8 cm i bio je naboran kako bi omogućio pokretanje. Osborn je pretpostavio da je bio dovoljno visok za još jedan red grupa krljušti.<ref name=HFO12/>
The only impressions from the head came from the large opening for the nostrils. Instead of tubercle impressions, there were impressions of folded soft tissue, with a deeper area at the anterior end of the opening that may have been the approximate location of the nostril itself.<ref name=LW42d/> The neck and back had a soft ridge or frill running down the midline, with a row of oval tubercle clusters arranged above the spines of the vertebrae. The total height of the ridge on AMNH&nbsp;5060 is not known, nor the disposition of its upper border, as the upper extremity was prepared away. The ridge was at least {{convert|8|cm|in|sp=us}} tall, and was folded and creased to permit movement. Osborn proposed that it was tall enough for another row of clusters.<ref name=HFO12/>

Rep nije pronađen kod primjerka AMNH&nbsp;5060, ali ostali primjerci dali su neke detalje o koži na tom dijelu tijela. Skin impressions from a partial tail belonging to either ''Edmontosaurus'' or its close relative ''Anatotitan'', recovered from the [[Hell Creek Formation]] of [[Montana]], show a segmented ridge above the vertebrae. The ridge was about {{convert|8.0|cm|in|sp=us}} tall, with the segments being about {{convert|5.0|cm|in|sp=us}} long and {{convert|4.5|cm|in|sp=us}} high, spaced {{convert|1.0|cm|in|sp=us}} apart, with one segment to a vertebra.<ref name=JRH84>{{cite journal |last=Horner |first=John R. |authorlink=Jack Horner (paleontologist) |title=A "segmented" epidermal frill in a species of hadrosaurian dinosaur |journal=Journal of Paleontology |volume=58 |issue=1 |pages=270–271}}</ref> Još jedan fosilizirani rep, ovaj put od neodraslog primjerka, imao je fosilizirane otiske uključujući tuberkule i do tada još neviđene teksture na koži.
