Well in Jurassic Park 3 they had quills. But that slight bit of accuracy was offset by the whole "dey wer smurtuhr den prim8s" thing. And yeah, I wouldn't mind a full fluff bunch of Raptors. But it'd be canonically weird. The entire shtick with the JP raptors are that they're two different Velociraptor species which... never existed. So it's not crazy to think they wouldn't have the same traits as real ones.

I hope Godzilla has feathers too.
