Just checked on http://research.amnh.org/vertpaleo/dinobird.html, the description of Sinornithosaurus and a photo of the Berlin specimen. It's true. However, phalanx II-2 is not expanded, leaving me scratching my head and asking why. (If both were expanded, like they are in pygostylians, the purpose -- better support for the wing feathers -- would be clear.)
Still? Like in PDW (when that was apparently mainstream)?
Reminds me of something...
`--+--Troodontidae (and probably "the rest of Arctometatarsalia")
`--+--Oviraptorosauria (and the rest of "Enigmosauria"
`--Pygostylia (and Yandangornis and whatnot)
Based on probably totally different (and probably much fewer) characters (and not actually a cladogram, as not run through a computer), but strangely similar, isn't it? :-)
:-D :-D :-D I had to laugh for a minute about that! Congratulations!!! That was the technical term that was missing! :-)
What do these abbreviations mean?
Looking forward for tomorrow! :-)
