Here is a quickie of the abstract, after the sentences you did (there

_Chaoyangia_ and _Songlingornis_, I would guess, both of which are regarded as basal Ornithurae (Chaoyangiformes).

Compared with other Cretaceous
birds, such as Confuciornis, Liaoxi and Shifan,


_Confuciusornis_, _Liaoxiornis_.. but "Shifan"? - is this _Jibeinia_?

[snip] same line
as modern birds (including neornithes radiation and distribution), it is
obvious that they are all different than [Shizhu Bird] ,


"Shizhu Bird"? - no idea at all what this is.

Looks like Mesozoic birds are now coming out of the woodwork.  Bring 'em on!
