Matrix 3.1

["David Marjanovic" <david.marjanovic@gmx.at>]

Character 21 is deleted for being uninformative (only arctometatarsal taxa
have it among the included ones, basal pygostylians and *Yandangornis* don't
have it); 19 is rephrased as "proximal end of mt III width subequal to II
and IV (0), narrower or absent (1), broader (2)" and given to *Yandangornis*
and Pygostylia because *Iberomesornis* has the condition. I have yet to
visit the museum for the condition in *Confuciusornis*; *Alvarezsaurus*, as
illustrated in Glut's Encyclopedia, has a proximally slightly narrowed mt
III, so I gave Alvarezsauridae 1.
All multistate characters except 7 are unordered.
Several silly typos are corrected -- as always, everyone is invited to find
more and to fill in some of the ? and - I had to make in some cases where
the relevant bones are known. Likewise, everyone is invited to rip the whole
thing apart.
(Boy, am I copying the passive style so common in scientific writing...
;-) )
