Not at all! Well, not quite. I remain quite firmly convinced that
dromaeosaurs and archaeopts are sister groups, and that this group, the
Archaeopterygiformes, is the sister group to the birds, including arctomets.

I took another look at the drawings in the _Dinosauria_ (but who knows
how much those really have to say, given the poor nature of the
material), and this animal looks like it might possibly be a sister taxon to
all other ornithomimosaurs, including _Pelecanimimus_. Or it might be
some other kind of arctomet, convergent on ornithomimosaurs. Hard to say
