This claim is contradicted by two separate analyses documented here:
https://en.wikipedia.org/wiki/Dromaeosauridae
Can you point me to an analysis that supersedes the two analyses on this Wiki page?

But it is relevant to paleontology, which Erik Simpson claims to want me [no mention of you] to focus on.

You keep resisting this simple course of action, so unlike my actions wrt the "microraptor" issue below,
and so the following stands unaddressed:

Actually "Coelurosaurs" was a titanic broadening of the claim after the initial "Dromaesaurs,"
a hefty clade intermediate between Maniraptorans and Deinonychids.

I've entered it now. It is totally relevant to your claim "failed to make clear."

He could have made it clear by naming some taxon, be it cladistic or Linnean. Hence this
red herring of yours is completely unsupportive of "failed to make clear".

Did you bother to look at it? It sure doesn't look that way from what you wrote below.

You are relying on a single sound bite below, a sentence that talks
about "features" (characters) and not about taxonomic placement.

These advanced characters argue that microraptors represent derivatives of, rather than being ancestral to, the early avian radiation, with dromaeosaurids at all stages of flight and flightlessness. They are literally bristling with uncoded avian characters, but these are swamped in cladistic analyses by the background noise of co-correlated characters associated with bipedalism and a mesotarsal foot joint. Interestingly, the microraptor *Sinornithosaurus*, typically reconstructed as an earthbound cursor, had elongate hindlimb flight feathers, which would have impeded ground locomotion, and exhibits a well-developed posterolateral bony flange and a strongly bowed outer metacarpal, making its hand better suited for support of primary feathers than that of *Archaeopteryx* (Paul 2002). As Paul notes (p. 407), “The combination of a well-developed posterolateral flange and a strongly bowed metacarpal III [outer metacarpal] made the hand of flightless Sinornithosaurus better suited for supporting primary feathers than was the hand of flying Archaeopteryx.”

Why are you asking this loaded question here, after a listing of features that you
do not deny to be avian?
Nor do you argue that *any* of them are found in theropods besides the ones that people you
disparagingly dismiss as "fringe" decided (close to a decade *earlier*) to be nested within what
was then called "Aves," WITHOUT moving them out of Theropoda.
When I say "earlier" I mean: before this 2013 article which you brought up but were too lazy
to find an url for, unlike Glenn.
And you are totally ignoring the issue of "They are literally bristling with uncoded avian characters..."
Do you claim that they are NOT "uncoded"? I know of some that are NOT coded: feathers and dinofuzz,
which orthodoxy labels as "protofeathers," and everything thought by orthodoxy to be in between.

Illogical use of "conflates" noted. If you didn't focus on one isolated claim in the long
article, you would know that it isn't afflicted with tunnel vision like you are. Quite the opposite.
> Paul did not.
More tunnel vision by yourself. Do you even care about the solidly paleontological
comments that Paul made?

By "there" I meant the quote from that 2013 article up there.
> Been done to death long ago.
If so, it was by people other than yourself, because I've never seen you address any of the
paleontology or cladistics that followed the opening sentence of what I quoted.
That is, with one exception: we did discuss the "frame shift" issue a number of times before,
which is why I brought it up right after that opening sentence.
> Why are you trying to resurrect this silly discussion?
There is nothing silly about the host of topics that followed that first sentence.
It's obvious that you are afflicted with tunnel vision about the whole paragraph.
> What is this obsession with Feduccia?
Your tunnel vision marks it as your obsession.
