I'm just saying that's the reason they went with it. They already have non-feathered raptors anyway so they probably thought having Ankylosaurus getting killed so easily wouldn't be that big of a problem, though I personally thought the Ankylosaurus fight was more of a disappointed than the lack of feathers.
