摘　　要：近年来四川盆地不断发现恐龙化石,引起人们极大关注。本文以四川省安岳县最新发现的恐龙动物群埋藏特征,初步探讨其环境意义。一、安岳恐龙化石埋藏特征已发现的安岳恐龙化石均埋藏在侏罗系上统上部地层中(图1)。我们重点对顶部马蹄寺和隆家崖化石点进行了发掘。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.
