_Microraptor_ is not included in this analysis.  Given the fact that
_Micro._, like _Sinornithosaurus_, seems to show more "troodontid"-like
features than the big bruiser dromaeosaurs of the mid-to Late K, it would be
extremely interesting to see how adding it to the analysis would affect the
shape of the tree.  Of course, that would require more detailed study of the
_Micro._ material.

Also of interest would be the position of "Dave" (if it is distinct from
_Micro._ and/or _Sinornithosaurus_).
