Experiment Will Determine Dinosaur's Skin Color

It's unlikely that this creature had feathers. Feathers are only known in Coelurosauria, which is a subset of theropods that, for example, includes Tyrannosaurus but not Allosaurus.

The hadrosaur under study is an ornithischian - a very, very distant relative that's more closely related to Stegosaurus and Triceratops. Psittacosaurus, a primitive horned dinosaur, did have tail bristles, but they appear to have been decorative for display and not feather-like at all.
