RE: Dinosaur Revolution Review

  Isn't it possible that those seemingly naked patches of skin were actually 
covered in protofeathers in life? Perhaps it was sparsely covered not unlike 
some of the more hairy members of Homo sapiens? 

The proportions are a bit off, but I think this restoration is one of the most 


It sort of reminds me of a Chinese dragon.

Also, what about Concavenator corcavatus? Are those bumps still considered to 
be possible quill knobs?
