The Early Cretaceous basal birds were known largely from just
two-dimensionally preserved specimens from north-eastern China (Jehol
Biota), which has hindered our understanding of the early evolution of
birds. Here, we present a three-dimensionally-preserved skeleton
(FPDM-V-9769) of a basal bird from the Early Cretaceous of Fukui, central
Japan. Unique features in the pygostyle and humerus allow the assignment of
FPDM-V-9769 to a new taxon, Fukuipteryx prima. FPDM-V-9769 exhibits a set
of features comparable to that of other basalmost birds including
Archaeopteryx. Osteohistological analyses indicate that FPDM-V-9769 is
subadult. Phylogenetic analyses resolve F. prima as a non-ornithothoracine
avialan basal to Jeholornis and outgroup of the Pygostylia. This
phylogenetic result may imply a complex evolutionary history of basal
birds. To our knowledge, FPDM-V-9769 represents the first record of the
Early Cretaceous non-ornithothoracine avialan outside of the Jehol Biota
and increases our understanding of their diversity and distribution during
the time.
