摘　　要：黑龙江嘉荫地区是中国最早发现恐龙化石的产地,在我国晚白垩世恐龙的研究史上具有极其重要的意义。该地区曾发掘出土大量鸭嘴龙类化石,是研究大型鸟脚类恐龙尤其是鸭嘴龙类系统分类和演化的理想地区。但相对应于鸭嘴龙类化石来说,兽脚类恐龙化石在该地区的发现却较为鲜见,主要以牙齿的形式出现。本文主要对最近在该地发现的一批兽脚类恐龙的牙齿化石进行详细描述对比,初步研究显示含有霸王龙类、驰龙类、白鲨齿龙、福井盗龙以及可能为新的兽脚类恐龙的牙齿。Jiayin area of Heilongjiang Province is the site,where the first dinosaur was discovered,and it plays a key role in the research history of Late Cretaceous dinosaurs in China.Lots of hadrosaurs had been found from this area,thus,it is the ideal place for the study of large sized ornithopod dinosaurs especially the systematic classification and evolution of hadrosaurs.However,compared with hadrosaur skeletons,theropod dinosaurs are very rare,they are mainly represented by teeth.Through detailed descriptions and comparisons of these recently discovered theropod teeth from Jiayin,the preliminary study indicates that these belong tyrannosaurids,dromaeosaurids,carcharodontosaurid,Fukuiraptor respectively and a possible new theropod.
