| 摘 要： | 攀西地区没有白垩纪恐龙骨骼化石记录,对该区白垩纪恐龙动物群组合的认识尚属空白。1991年,攀西地区首次发现了恐龙足迹,此后陆续发现了8个足迹点。这些足迹点共发现9种不同的非鸟恐龙足迹(6种非鸟兽脚类、1种蜥脚类和2种鸟脚类足迹),以及翼龙和龟类足迹。共11种足迹形态类型由185道行迹(与孤立足迹)组成,可能代表着同等数量的造迹者。其中飞天山组的组合多样性最强,小坝组和雷打树组较弱。这个相对全面的足迹数据库,为该地区白垩纪四足类的古生态学普查提供了动物群的组成信息,这在该缺乏骨骼化石的地区显得尤为重要。

| Abstract: | The Panxi region has rich Cretaceous dinosaur ichnofaunal assemblages. Since the discovery of fossil tracks in 1991, no fewer than 11 track morphotypes have been recognized from at least 8 tracksites. They include 9 different dinosaur track types (attributable to 6 non-avian theropod, 2 avian theropod, and 1 sauropod trackmakers) and tracks of pterosaurs and turtles, which occur within 185 trackways (and isolated footprints) and may reflect trackmakers of the same number. This high ichnofaunal diversity within the Feitianshan Formation exceeds that of the Xiaoba Formation and Leidashu Formation, and provides a comprehensive track database that permits (but is not limited to) a greater understanding of the paleoecology of an area where body fossils are currently unknown. |
