_Therizinosauria_ (well, "therezinosaurs [sic]") was defined as "_Alxasaruus_,
_Enigmosaurus_, _Erlikosaurus_, _Nashiungosaurus_ [sic], _Segnosaurus_, and
_Therizinosaurus_ ... and all others closer to them than to oviraptorosaurs,
ornithomimids, and troodontids." This takes a variety of possible positions
into account.
