No, there are many traits that some therapods had but not necessarily all of them. But if birds came from therapods we would expect to see at least some therapods with these traits. For example hardly any therapods had wings. Most didn't. Wings ARE an avian trait. I don't know how many therapods had feathers, but archaeopteryx definitely had them. Feathers are an avian trait. Very few therapods flew. Archaeopteryx flew. Flying is an avian trait. And please don't cite the few nonflying birds. Over 99% of birds can fly so yes, flying is an avian trait.Archeopteryx is not an intermediate anything because all it cited intermediate traits are actually theropod traits.
Maz, it would help you if you took a basic logic course.
