摘要

The Sichuan Basin,also known as the 'Red Basin',is famous for its abundance of Mesozoic dinosaur fossils,especially in the Zigong area during the Jurassic era;the Middle Jurassic Shunosaurus and the Late Jurassic Mamenchisaurus faunal assemblages are the most representative.The Qinglongshan dinosaur fossil site is located in Fuxing,to the northwest of Rong County,Zigong City.This new site is situated within the Middle Jurassic Xiashaximiao Formation,and geologically is roughly equivalent to the well-known Dashanpu dinosaur fossil site.More than 600 dinosaur fossils were found concentrated in the excavation area,including teeth;cervical,dorsal and caudal vertebrae;and various parts of appendicular skeletons.This fossil site is also most significant as it provides new information on non-avian dinosaur life during the poorly understood Middle Jurassic.
