In this contribution, I will discuss the measurements using synchrotron radiation that led to the discovery of a remarkably well preserved skin layer of a hadrosaur from the Grand Prairie region. This is first ever observation of preserved epidermal skin layers in a large dinosaur. I will also present a direct comparison between these structures and those from an extant avian specimen, giving the first substancial evidence of the similarities between the organic layout of the skins of extinct non-avian and extant avian dinosaurs.
