As has already been pointed out, Pseudosuchia should be discarded in favor of 
Crocodylotarsi.

For the sister taxon, I would recommend Ornithotarsi, which has the 
advantages of being both more consistent and less cumbersome and which is 
actually equivalent to "Avemetatarsalia", since "flat of the foot, 
metatarsus" is one meaning of Greek "tarsos".
