I agree to an extent with this if I understand your standing correctly.

This could just be an example of a preservation bias.  Anyway, you 
cannot use the fact that the birdlike dinosaurs came after 
_Archaeopteryx_ as proof that they are descendents of _A._.  More 
evidence should be gathered.  Thus far, I think that the evidence shows 
that these creatures are long-surviving relicts that were close to the 
ancestry of birds.  You cannot look at _Archaeopteryx_ and get a perfect 
dromaeosaur, _A._ is too birdlike and derived.

Of course, you have to show that the birdlike dinosaurs evolved from the 
first-known bird.

Many so-called "dinosaurs" are also.  The fact >that cladistics doesn't

Where is your proof other than the temporal 'problem' (?) and the 
existence of feathers?  Here's what I see;

_Archaeopteryx_ is extremely birdlike with the hooked ectopterygoid, no 
serrations on teeth, etc, birdlike braincase, single sternum, etc. 

Advanced birdlike dinosaurs show few of these features.

'Nuff said.
