RE: Dinosaur Revolution Review



Didn't Leonardo (the Brachylophosaurus mummy) have some naked patches as well? 
If so, then I wouldn't find it very surprising that we see something similar in 
Tyrannosaurids. Maybe both had a mix of naked and scaly skin, and maybe both 
evolved from fuzzy ancestors?
