Its only [[species]], '''''Yi qi''''' <ref>from {{zh|c=翼|p=yì|l=wing}} and {{zh|c=奇|p=qí|l=strange|labels=no}}</ref> is known from a single [[fossil]] specimen of an adult found in [[Middle Jurassic|middle]] or [[Upper Jurassic|late]] Jurassicof Hebei, China. It lived about 160 million years ago. ''Yi'' was a small, possibly tree-dwelling ([[arboreal]]) animal. Like other of its family, ''Yi'' had an unusual, elongated third finger. This helped to support a [[membrane|membranous]] gliding plane (aerofoil) made of skin.<ref>Xu X. ''et al'' 2015. A bizarre Jurassic maniraptoran theropod with preserved evidence of membranous wings. ''Nature''. '''521''', 70{{ndash}}73. [http://www.nature.com/nature/journal/v521/n7550/full/nature14423.html]</ref> The gliding planes of ''Yi qi'' were also supported by a long, bony strut attached to the [[wrist]]. This modified wrist bone and gliding membrane is unique among all known dinosaurs, and might have resulted in wings similar in appearance to those of [[bat]]s. == References == {{reflist}} [[Category:Theropods]] [[Category:Feathered dinosaurs]]
