The metatarsi in question are sort of "subarctometatarsalian": they are not
as fully pinched as caenagnathids, troodontids, ornithomimids, _Garudimimus_
(which resembles caenagnathids more than published drawings suggest), and
tyrannosaurids (or as "hyperartcometatarsalian" as mononykines or
_Avimimimus_).
