摘要: 结合以往的研究对发现于甘肃马鬃山地区公婆泉盆地和俞井子盆地的恐龙化石进行了总结。基于恐龙化石的产出层位和组合成员的相似性，将两地的恐龙归入同一个恐龙化石组合——马鬃山恐龙化石组合，其时代为早白垩世阿普特中晚期—阿尔布早中期。另外，通过与辽西热河生物群早白垩世的恐龙化石进行对比，归纳出该组合的特点。马鬃山恐龙化石组合对深入研究中国北方早白垩世恐龙化石的演化过程具有重大意义。

Abstract: Dinosaur fossils from Gongpoquan and Yujingzi basins in the Mazongshan area of Gansu Province were reviewed in this paper, and they can be assigned to the Mazongshan dinosaur assemblage (Aptian—Albian) based on the similarity of the output layers and members of dinosaur fossils. This assemblage has several characteristics by comparing with dinosaurs from the Jehol Biota. In general, Mazongshan dinosaur fossil assemblage is of great significance to further study of dinosaurs from Early Cretaceous strata of northern China.
