True. Senter et al.'s dissertation includes Avimimus and three segnosaurs

So the Oviraptorosauria+Therizinosauroidea clade falls apart? Is
_Beipiaosaurus_ included in the analysis?
Segnosaurs as arctometatarsalians...? As remarked upon previously,
troodontids and therizinosauroids share quite a similar dentition. If
alvarezsaurids are included in this clade, along with segnosaurs and
bullatosaurs, then what we end up with is a major clade of
non-hypercarnivorous maniraptoriforms (assuming troodontids were
A small nit-pick- Senter et al.'s Dromaeosauridae
is Padian et al.'s (1999), so would exclude Bambiraptor if the topology was

fickle mistress... or something to that effect.
I think it's worth noting _Bambiraptor_ is not coming out as sister taxon to
_Saurornitholestes_. For a while there was a suggestion that the two might
be synonymous. I think this was wishful thinking on the part of those
(myself included) who despised the name _Bambiraptor_ and wanted to see it
buried as a junior synonym of _Saurornitholestes_. :-) But at least it
seems we can kiss goodbye to _Cryptovolans_.
A final note: I wonder what impact _Omnivoropteryx_ will have on
maniraptoran phylogeny, especially vis-a-vis the topology of basal
