Pachycephalosaur

Pachycephalosaur dinosaur which lived in the Cretaceous.  The line art was created by Russell Hawley.

While I did not draw the line art for this image, I did color it, using GIMP, for use in the museum where I work.  I have full permission from Russell to post my coloration of this here on DA.   I chose a mossy, muted gray-green for this guy mainly because I can imagine them living on rocky hills where such coloration would help them blend in, at least for most of the year.  I didn't go with the brighter "mating plumage" coloration I had in mind just because I didn't want to play with that many colors when I colored this.
