Qiliania graffini gen. et sp . nov

Abstract:
In recent years, the Lower Cretaceous (Aptian) Xiagou Formation has yielded
approximately 100 avian partial skeletons, many with soft-tissue traces,
from sites in the Changma Basin of Gansu Province, north-western China. The
most abundant taxon amongst these is the ornithuromorph Gansus yumenensis,
but enantiornithines have also been identified in the sample. Here we
describe two incomplete, semi-articulated appendicular skeletons, the first
consisting of a partial left pelvic girdle and complete pelvic limb, and
the second comprised of a nearly complete right pelvic limb. Both specimens
bear characteristics diagnostic of Enantiornithes, and are referred to a
new taxon, Qiliania graffini gen. et sp. nov. The exceptional,
three-dimensional preservation of these specimens (compared to the crushed,
nearly two-dimensional condition of most other Early Cretaceous avian
fossils) reveals new information regarding enantiornithine anatomy,
evolution, and diversity.
