basal Bilateria ... where do Acoela and Nematodermata fit in? Xenoturbellida?

>Certainly Reptilia seems well-cracked

then please point me to a fully-worked out published Linnean classification 
which is congruent with the phylogeny (i.e., with mammals and birds as 
subordinate to the class Reptilia, but still with Linnean ranks) ...

But name me an uncrackable paraphyletic group (I'm not saying there 
aren't any, I just can't think of any off the top of my head). Certainly 
Reptilia seems well-cracked.
