Another Alxasaurus query (was: thanks and ...)

Aren't they considered to be?

With all due respect to George (and I don't mean that sarcastically),
is there real controversy among dinosaur paleontologists about the
assignment of these dinosaurs ("therizinosaurs"/"segnosaurs")?

If so, has anyone published a critique of the Russell/Dong analysis in
a (all together now) peer-reviewed scientific journal?

The fourth toe is awfully odd, isn't it?  Is there an analogy that can
be drawn in, say, extant mammals?
