...Um, Justa, you do realize that cladistics stack, right? A turkey is a member of Ornithurae. All members of Ornithurae are members of Euornithes, and all members of Euornithes are members of (I don't feel like spelling or copying right now).Sure does - that you got turkey's classed wrong. And hope people won't catch your mistake of putting one in the clade Ornithurae and the other Dinosauria. Then put the other in the clade Aves - even if it already belongs to the clade Donosauria.
Like I said - can't be consistent from one post to the next. So is the clade Dinoauria, Ornithurae, or is it Aves - because it can't be all three. No other animal that is known to exist is classified as such. Because the reality is you have not a clue as to where to put them, so you put them in three different clades so evolutionists can pick and choose on any given day what clade they want them to belong to. Sad.
Maybe this would be easier to understand from the other direction.
You have your clade, Dinosauria. All animals in this clade share certain characteristics. However, you can further subdivide this clade. For example, the members of Dinosauria can be split into two types of hip structure, giving us Ornithischia and Saurischia. Now, the members of Saurischia are still members of Dinosauria; they're simply more specified. We can say more about the organism, and more about its descent. We can continue using similarities and differences to subdivide into further and further clades, further expanding and specifying the cladogram.
It's not just that an animal is in Aves, Ornithurae, and Dinosauria. ALL members of Aves are also members of Ornithurae and Dinosauria! Just like you are a primate, a mammal, and an animal. You cannot out-grow your clade; you cannot evolve out of your own ancestry. I mean, to put it another way, you do understand that you are in the clades of Mammalia, Primates, and Animalia, right?
I don't mean to sound mean, but if you don't understand this, you should not be disputing cladistics or evolution in general. You have serious holes in almost every aspect of your education with regards to biology, and you'd do well to avoid the subject.
