BURIAL FEATURES AND ENVIRONMENTAL SIGNIFICANCE OF THE DINOSAURS FROM ANYUE,SICHUAN

Following the Mamenchisaurus hochuanensis and Zigong dinosaur faunas, the Anyue dinosaur faunas were discovered in Anyue, Sichuan in the past few years. The emphasis in this paper will be on the Matisi and Longjiaya fossil beds. The dinosaur fossils from the former were found to be preserved in the sandstone lens in the Upper Jurassic Suining Formation, whereas those from the latter in the sandstones in the Upper Jurassic Penglaizhen Formation, both of which are interpreted as the littoral lacustrine facies.
