摘　　要：栾川地区脊椎动物化石赋存在上白垩统秋扒组的中下部,时代可能为坎潘期晚期,以小型兽脚类恐龙骨骼为主。化石点大多分布在潭头盆地北部边缘2 km的范围,搬运距离不远。栾川动物群的化石组合包括至少8种恐龙(其中已命名6种)、2种蜥蜴类、2种哺乳类及数量众多的恐龙蛋等,代表一典型晚白垩世动物群,称为栾川动物群。栾川动物群与中国南方的赣州盆地和蒙古Nemegt盆地晚白垩世恐龙动物群具有很高的相似性,均以兽脚类恐龙为主,兼有其他脊椎动物组合。栾川动物群的研究对了解东亚晚白垩世恐龙动物群的生态面貌、恐龙多样性演化,以及环境变化对恐龙迁徙和灭绝的影响等具有重要意义。Vertebrate fossils from the Luanchuan area in Henan Province,dominated by small theropods,are mainly from the Late Cretaceous Qiupa Formation(Campanian).Most of the fossil sites are distributed within 2 km in the northern margin of Tantou Basin,and the transport distance is not far.Vertebrate assemblage includes at least 8 dinosaurs(with 6 named dinosaurs),2 lizards,2 mammals and abundant dinosaur eggs/eggshells,and it represents a distinct Late Cretaceous fauna named as“Luanchuan Fauna”.Luanchuan Fauna is similar to those of the Late Cretaceous dinosaur faunae from the Ganzhou Basin and Nemegt Basin,which are all represented by theropod dinosaurs along with other vertebrate animals.Luanchuan Fauna is of great significance for understanding the ecological features of the Late Cretaceous dinosaur faunae in East Asia,the dinosaur evolution and diversity,and the impact of environment changes on the dinosaur migration and extinction.
