Anomalipes zhaoi ("meaning Zhao Xijin's unusual foot") is an extinct caenagnathid dinosaur discovered in the Campanian-aged Wangshi Group in China. It is the only species in the genus Anomalipes.[1]


The remains of Anomalipes were discovered within a Shantungosaurus bonebed at the Kugou locality. The holotype (ZCDM V0020, housed at Zhucheng Dinosaur Museum, Zhucheng, Shandong) is an incomplete left hind-limb, including a partial left thigh, shin and shank, a complete metatarsal III and two toe bones.


Anomalipes is derived from the Latin anomalus (peculiar, abnormal, not easily classified) and pes (foot), referring to the unusual shape of its foot. The species epithet, zhaoi, was named in honour of Zhao Xijin.
