With Jurassic World and dinosaur hype running wild this weekend, I pose a question of intense debate amongst paleontologists the last several years. Several species of tyrannosauroids have been found with evidence of downy proto-feathers. The largest of these, Yutyrannus, was an ancestor to the T-Rex and was covered from head to toe in downy feathers. It's size was also pretty comparable to smaller T-Rexes, and the climate in which it lived only differed from Rex's by a couple of degrees Celsius. So what do you think?
