Abstract: A karstic cave called Laodong with rich Late Miocene mammals was found in 1990 in the Dajushan(117°01′E,3235′N) area,15 km northwest of Huainan City, Anhui Province in eastern China(Jin et al.,2000; Jin,2004). During the implementation of the State Key Project of the 9h Five-year-plan", Jin and colleagues found two other fossil localities. One of them is located in a fissure called Xiliexi(it means West Fissure in Chinese) and about 60 m west of the Laodong Cave. Many mammal fossils were unearthed from the fissure deposits. Some specimens of Sus lydekkeri were identified as below.
