Phylogeny of basal birds 3/3



And then I took those with 20 or fewer coded characters away (*Hulsanpes*,
*Noguerornis*, *Halimornis*, *Lectavis*, *Yungavolucris*, *Avisaurus*,
*Alexornis*, *Soroavisaurus*, *Boluochia*, *Otogornis*, "unnamed Lebanon",
*Liaoningornis*, *Ambiortus*, *Vorona*, *Songlingornis*, *Gansus*). Only 199
MPTs resulted, reweighting reduced this to 180.

If someone wants the NEXUS file and/or the treefiles (I'll try to correct
the treefile with the results of the unweighted search without those with 10
or less codings), please tell me.

I'll look for a few apomorphy lists in my gigantic log file. I can tell from
memory that Enantiornithes is held together by the long hypocleidium and 2
or 3 other characters.

The promised "paper" is not finished, not even the German version. I've made
a neat PowerPoint presentation about my work, but it doesn't contain the
trees (TreeView has some problems...) and contains so many pictures that it
has almost 15 MB, so I probably can't send it.
