Re: Jeholornis



From the site,

Abstract: The recently reported Jeholornis represents the only known bird with a complete long skeletal tail except for Archaeopteryx.

Does _Rahonavis_ not count because its tail isn't completely known, or because it isn't a "bird"?


More interestingly, the tail feathers are shaped more like those of >dromaeosaurs than those of Archaeopteryx.

Are there any other feathers preserved? Two or four wings? :)

We conclude that the common ancestor of birds must have a more >primitive tail than that in Archaeopteryx, confirming the side branch >position of Archaeopteryx in the early avian evolution.

Should that be said about _Archaeopteryx_ when _Jeholornis_ is clearly a side-branch? Which tail shape allows for better flight ability?
