Archaeopteryx not a bird?

Darren Naish has a great blog post about Archaeopteryx.

Our 'whole theropod' analysis, with (again) our new big bird (Samrukia) within Ornithuromorpha. Some other taxa of special interest are marked with arrows, including Oviraptorosauria, Archaeopteryx and Avialae. From Naish et al. (2011, online supp. info).Note that our result actually isn’t the same as Xu et al.’s seeing as, unlike them, we didn’t find Archaeopteryx to be a deinonychosaur. I’d also like to take this opportunity to note that the moving ofArchaeopteryx out of Avialae really isn’t a big deal, or a surprise – it amounts to a shift of a node or two, and quite a few theropod workers have been saying for years that it’s probably only a matter of time before phylogenies start findingArchaeopteryx to fall outside of Avialae. Given what we now know about early dromaeosaurids, troodontids and oviraptorosaurs, and about Anchiornis, scansoriopterygids and so on, it’s clear that working out the relationships among these confusing and often very similar feathered little maniraptorans is not going to be easy. Indeed, don’t go thinking that the notion of a non-avialian Archaeopteryx is necessarily here to stay![Big birds in the Cretaceous of Central Asia: say hello to Samrukia]
