A new enantiornithine bird, Bohaiornis guoi, gen. et sp.
nov., is described in this paper. The holotype,
presumably a sub-adult, is a complete, fully articulated
skeleton from the Lower Cretaceous Yixian Formation of
western Liaoning, northeastern China. Bohaiornis exhibits
some similarity in morphology to Eoenantiornis, but
Bohaiornis is much larger than Eoenantiornis and differs
from all previously known enantiornithine birds including
Eoenantiornis in having the following features: caudal
end of the articular pointed caudoventrally, sacral
centra strongly compressed transversely, and clavicular
ramus straight with a laterally expanded omal end. The
almost perfectly preserved skeleton of this new specimen
not only reveals many morphological features previously
unknown in basal birds, but also clarifies many fine
details of previously known features.
