RE: Rahonavis (was Re: Ornithoms, Parrots, and others)

I suspected that _Rahonavis_ would fall out as a deinonychosaur in my
phylogeny, but in my latest runs it comes out as a basal avialian
(closer to
birds than to dromaeosaurs).  However, as it is so fragmentary, and as
newer specimens of dromaeosaurids from both the Cloverly and Mongolia
showing a wider ranger of morphologies within that taxon, I wouldn't be
terribly surprised if it didn't make the hop over to the dromaeo-side of

This suprises me, I thought that the case for the avian status of Rahonavis
was quite good, judging from the original description in Science.
