You see, dromaeosaurids, Ornitholestes, and tyrannosaurids are all
relatively close to each other. Just as I suggested a long time ago, but no
longer believe for obvious reasons. ;-)
`--+--+--+--Alxasaurus

Aside from the placement of Avimimus as an oviraptorosaur and Archaeopteryx
and dromaeosaurids not being sistergroups, it does not appear all that
different from the phylogeny suggested by Gregory S. Paul in Predatory
Dinosaurs of the World.
Did you include the characters in Makovicky's PhD thesis that found
Ornitholestes close to the dromaeosaurids or the characters that HP Headden
suggested for the possibility of O. being close to oviraptorosaurs?
I had to exclude Therizinosaurus and Borogovia due to the fact no cranial
or axial remains are known.
You will of course be including them in the rest of your analysis, right?
Interesting. Confuciusornis ended up as an avian, far away from
oviraptorosaurs.
Will you be including Sapeornis, Epidendrosaurus, Cryptovolans,
Changchengornis, Jibeinia, Erliansaurus, Neimongosaurus, Nothronychus,
Eshanosaurus, and Protopteryx in your analysis at all? And have you
considered coding Oviraptoridae as separate OTUs?
I'll probably do another update when I
get most of the pectoral and forelimb characters coded.
W4MA... ;-)
