Thanks a lot. :-) The new *Sinornithosaurus* paper cites E & W 1996 _for_
that feature in Archie, though, and in some (not all) figures in the latter
paper the quadratojugals do look fully triradiate. I'll have a look at
*Erlikosaurus*, but so far this character (by itself) looks a lot like an
autapomorphy of a clade that includes Archie and the "dromaeosaurs" but not
Pygostylia.
