Herein we describe a new species of Microraptor from northeastern
China that provides new information on the characteristics of the
genus and anatomical details suggesting a gliding behaviour. Although
specimens of Microraptor have been known for at least a decade, the
completeness of the new fossil provides additional morphology that
highlights the uniqueness of this taxon. The new specimen, Microraptor
hanqingi, is the key to understanding the evolutionary significance of
hindlimb wings. A four-winged structure present on an organism sharing
an evolutionary lineage leading to modern birds implies that gliding
was a stage in the development of avian flight. M. hanqingi represents
the largest known microraptorian from China with a total length of
approximately one meter, and was closely-related to the venomous form,
Sinornithosaurus.
