Where do you pick up this junk science, the Creation Museum?
You said: "The fact that it had teeth is irrelevant to its alleged transitional status—a number of extinct birds had teeth, while many reptiles do not. Furthermore, like other birds, both its maxilla (upper jaw) and mandible (lower jaw) moved. In most vertebrates, including reptiles, only the mandible moves."
Gee...where do I start! How about this ... "The lower mandible is the lower part of the bill and in many birds, this is the only part that moves. It is in function and location similar to the human’s lower jaw. Certain species, such as the parrot, are able to move both mandibles."

And this doesn't click in your religious brain that it might just be more proof for evolution?
Both are further evidence that Archeaoptryx was simply another bird, not a dino/bird transitional creature.
