摘要	Polydactyly and other malformations such as supernumerary limbs are relatively common in extant salamander populations. They generally result from biotic or abiotic disruption of normal regeneration following non-lethal predator or conspecific bite injury. Here, we record, for the first time, similar malformations in a fossil salamander. Fourteen specimens of the perennibranchiate Jurassic salamander Chunerpeton tianyiensis (Urodela, Cryptobranchidae), recovered from Jianping County, Liaoning Province, China, display polydactyly or abnormal phalangeal counts in one or more limbs, and two also possess supernumerary hind limbs. Polydactyly in Chunerpeton is mainly post-axial, occurring on the feet more often than the hands, and on the right side of the body more often than on the left. The extra legs also occurred on the right side of the body. Similar conditions can be observed in living salamanders, so these specimens suggest that the challenges faced by aquatic salamanders, and the developmental processes triggered in response, have changed relatively little in 160 million years.
