Select all the following characteristics that Mesozoic birds (specifically Archaeopteryx) had that modern birds do not. Not sure why I keep getting this wrong.

answer; i believe the correct answer is (anemia);

if someone had the list of traits you provided

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
