Re: The cladogram from the supp. inf. of the *Anchiornis* paper
Keep in mind this is just the Epidexipteryx analysis with Anchiornis
added, and the Epidexipteryx analysis was just Senter's (2007)
analysis with Epidexipteryx added.
The character list does contain lots of refinements such as plenty of
added states. Still, though, it seems that all characters were
unordered. :-(
Anchiornis may very well be a troodontid, but note the matrix doesn't
include Mahakala, Yixianosaurus, Shanag, Austroraptor, Sinusonasus
or Jinfengopteryx.
True, these are highly relevant omissions.
Also note that the original Anchiornis matrix
included 48 characters from Xu's thesis that are useful for basal
paravian phylogeny. These are not present in the new Anchiornis
matrix
Ouch.
My modified version of Senter's
analysis already includes all of the data from both of these studies
except I haven't added the new Anchiornis codings yet. My site
should be updated before the new year with those results (after the
upcoming update with ornithuromorphs).
:-) :-) :-)
Also notice the new taxon in the supplementary info-
Alvarezsauroidea.
Wow, I didn't notice... I basically skipped the nomenclature section
except for Avialae and Aves, because it seemed unremarkable.
Unfortunately, it has an equivalent definition to
previous definitions of Alvarezsauridae, except it uses the eponymous
genus at last (the others used Shuvuuia).
<headdesk>
To counter that compliment
though, the authors use Deinonychus for Dromaeosauridae and
Ornithomimus edmontonicus for Ornithomimosauria.
Yeah. Suboptimal.
