Yet more questions about our favourite
dinobirds.
Was _Rahonavis_ any less flightworthy than
_Archaeopteryx_? From what I've heard, it looks like it's sort of
intermediate in "flightworthiness" between _Archaeopteryx_ and
_Sinornithosaurus_ (or vice versa, depending on your views on ground-up or
trees-down). Is this correct?
Who has a more advanced shoulder, _Sinornithosaurus_ or
_Unenlagia_?
In a recent article on _Sinornithosaurus_ in the _Globe and
Mail_, it also mentions a "130-million-year-old bird that was so highly
evolved by the late Jurassic-early Cretaceous period [that Feduccia] believes
there is no way it could have evolved from a dinosaur." What is this
bird? _Confuciusornis_?
Thanks in advance.
