Gliding squamate from the Yixian Fm



I am told (http://www.wissenschaft.de/wissenschaft/news/276176.html; in German) that PNAS has just prepublished *Xianglong zhaoi*, which looks like *Draco* or for that matter *Icarosaurus* but is not closely related to either, and is very well preserved, with strengthening fibers in the gliding membrane spanned between 8 lengthened ribs. The specimen is a 15 cm long juvenile. The wings have "aerodynamic values" that resemble those of active fliers. Claws for climbing trees were unsurprisingly present. The name means "flying dragon" (...the usual word for "flying" apparently being preoccupied by the pterosaur *Feilongus*).
