Yup. Arctometatarsalia is (Segno(Troodo(Deinocheir(Alvarez,Ornithom)))) in the dissertation [snip] alvarezsaurids are arctometarsalians in Senter's phylogeny.

Accordingly, phylogenetic bracketing woud require that _Deinocheirus_ had an arctometatarsalian pes, or secondarily lost it. Interestingly, under this phylogeny both _Deinocheirus_ and alvarezsaurids belong to an expanded Bullatosauria.
