| 摘 要： | 河南夏馆-高丘盆地出露一套富含恐龙蛋和恐龙骨骼化石的红色陆源碎屑岩系。20世纪70年代末,赵资奎(1979)将含蛋"红层"时代归为"白垩纪"。此后,该套"红层"曾称"高沟组"和"马家村组"、"桑坪组"、"夏馆组",但均没有测制正式地层剖面,无专门论文发表,原因是除恐龙(诸葛南阳龙)和恐龙蛋化石外,基本没有发现可资确定地层时代的无脊椎动物和植物化石。近年来,除新发现"河南宝天曼龙"外,2011年作者测制了系统剖面,并寻找到介形类、双壳类、腹足类、轮藻和植物大化石,有条件正式建立"夏馆组"组级地层单位并进行地层划分和对比。"夏馆组"的时代应为土伦(Turonian)中—晚期至坎潘(Campanian)中期。 |

| Abstract: | The red strata of a suite of bearing-dinosaur egg fossils are exposed in Xiaguan-Gaoqiu Basin of Henan Province. It has been called the Gaogou Formation, the Majiacun Formation, the Sangping Formation and the Xiaguan Formation, and the formal stratigraphic section has not surveied formerly. Because the invertebrate and plant fossils that can be used to can determined stratigraphic epoch have not discovered except the dinosaur and dinosaur egg fossils, so a monograph not yet came out. In recent years, the authers have surveied the systematic stratigraphic section and found the a abundent invertebrate and plant fossils in 2011 except new discovery of dinosaur fossil Baotianmansaurus. So, the establishment of the stratigraphic unit of the formation level and stratigraphic subdivision and correlation have already basic condition. This discovery indicates the Xiaguan Formation may be the early-middle Late Cretaceous in age, and most possibly the early-middle Turonian to the middle Campanian. |
