But indeed. I can readily believe that arctocyonids and
phenacodontids are paraphyletic (or even polyphyletic). Not crown
Scandentia or Carnivora though.

Unless _A. ajax_, _A. excelsus_, _A. louisae_, and _A.parvus_ do NOT
form a monophyletic group to the exclusion of other diplodocids, there
doesn't seem any point to reviving _Elosaurus_ - or _Brontosaurus.
