In reality, why would you want to say, "carnosaurs closer to x than y"
anyway? You could say "all animals" or even "all life closer to [for
example] _Ornithomimus_ than to Neornithes." This definition would ALWAYS
be valid even if it turned out that _Ornithomimus_ were some weird
convergent salamander! The clade would still exist!
