Not to sound like a broken record, but could people please wait to get the
details (as in "read the paper")?  Stidham *explicitly* compares it to
caenagnathid material, and finds many significant differences.  He also
finds some psittaciform synapomorphies on the specimen.

Not that skepticism isn't the key to science (it is, and I am a very keen
fan of it), but could people please wait to see the various papers and
analyses before assuming the authors didn't already think of this or that
particular point?

[I hope that something comes along soon so I can be posting positive, rather
than negative, comments on the list... :-S].
