It's not terribly shattering if there was a coelurosaur with no feathers. Not all of the traits that define a group have to appear at the same time. Traits can disappear. And, of course, there are evolutionary cul-de-sacs too. Fitting the piece into the puzzle correctly is the key.

And, of course, there are evolutionary cul-de-sacs too. Something a lot of people fail to take into account. Most fossil finds are "branches" off any main line connecting one species to another. Extinction plays a huge role in evolution & the formation of the fossil record that we observe.
