Xianglong
Extinct genus of lizards
Xianglong (meaning "flying dragon" in Chinese) is a genus of Cretaceous lizard discovered in the Zhuanchengzi, near Yizhou, Yixian, Liaoning Province of China.[1] It is known from LPM 000666, a single complete skeleton with skin impressions. The specimen comes from the Barremian-age Lower Cretaceous Yixian Formation, near Yizhou. The most notable feature about Xianglong is its bizarre oversized ribs, eight on each side, which were attached to a membrane of body tissue and allowed the lizard to glide. While in its original description it was considered to acrodont lizard, with a cladistic analysis in the same study suggesting that it was grouped with iguanians such as agamines, chamaeleonids, and leiolepidines,[2] it was later shown that this was due to misinterpretation of the crushed skull, and its affinities with other lizards remains uncertain.[3]
