| 摘 要： | 根据对黑龙江沿岸孙吴、逊克和嘉荫保兴-炮台店一带晚白垩世地层与嘉荫乌拉嘎、龙骨山等含恐龙化石群的渔亮子组(K2y)等对比及在前三个地区已发现部分恐龙化石的线索，初步预测孙吴北部、逊克东南部和嘉荫保兴-炮台店等三地区可能为较大规模的恐龙化石群产地。预测区含恐龙化石的晚白垩世地层均属河流-湖泊相沉积，除恐龙外，尚可能发现叶肢介、介形类、鱼、龟鳖类、鳄、鸟类及被子植物等伴生化石。上述地区下伏于渔亮子组的太平林场组(K2t)和永安村组(K2yn)等地层，也有含恐龙化石的可能性。

| Abstract: | Based on the correlation of the Upper Cretaceous from Sunwu,Xunke and Baoxing-Paotaidian of Jiayin along the Heilongjiang River,with the Yuliangzi Formation(K2y)yielding dinosaur fossils from Wulaga and Longgushan of Jiayin,and on some clues of outcrops of dinosaur fossils,the author forecasts that the three areas including the northern Sunwu,southeastern Xunke and Baoxing-Paotaidian of Jiayin would be new larger-scale sites of dinosaur fossils. In view of the lacustrine-fluvial sedimentary facies of the Upper Cretaceous strata in the three areas,some associated fossils with the dinosaurs such as conchostraca,astrocods,fish,turtles,crocodiles,birds and flowering plants would be found out there also. Dinosaur fossils may be found in Taipinglinchang Formation(K2t)and Yong'ancun Formation(K2yn)underlying the Yuliangzi Formation. |
