Re: Juehuaornis, new ornithuromorph bird from Lower Cretaceous of China
Some additional info and slightly revised citation as 34(1):
Wang Ren-fei , Wang Yan & Hu Don-yu (2015)
Discovery of a new ornithuromorph genus, Juehuaornis gen.nov. from
Lower Cretaceous of western Liaoning, China.
Global Geology 34 (1): 7–11 (Chinese Edition)
No open access version yet, but the text can be viewed and read online
at this link:
You can type in the page numbers at the bottom, hit "enter," and
click on the + expand view button on the bottom, and then use the side
> to go through the pages (7--11). Not a whole lot of info, but there
is a photo of the holotype and counterslab on page 8.
