I'd leave _Herrerasaurus_ outside Theropoda (which is diagnosed by the
"theropod foot," functionally tridactyl, hallux lowered and at least
partially retroverted, proximal part of metatarsal I absent, metatarsals
II-IV closely appressed: not a _Herrerasaurus_ foot at all). There can still
be an order Herrerasauria, within a larger group Theropodomorpha.
