摘要
离龙类是热河生物群具有代表性的脊椎动物,在辽西等地广泛分布,而冀北地区作为热河生物群的重要产地,在白垩纪地层中尚未发现离龙类信息.本研究在冀北滦平盆地确认了离龙类化石的存在,化石为满洲鳄未定种和离龙类未定种,产出于九佛堂组,时代为早白垩世.此次发现填补了河北省早白垩世离龙类化石的空白,为研究冀北热河生物群的生态环境和生命演化提供了新材料,对于研究中国北方热河生物群离龙类地理地史演化具有重要意义.
Choristodera,a representative vertebrate in Jehol Biota,is widely distributed in the western Liaoning Province.However,Choristodera in Cretaceous strata was not reported in northern Hebei Province,although it is the important producing area of Jehol biota.This study confirms the existence of Choristodera in Luanping Basin in northern Hebei and identifies the fossils as Choristodera sp.and Monjurosuchus sp.,occurred in Early Cretaceous Jiufotang Formation.The discovery fills a gap of Early Cretaceous Choristodera in Hebei Province,and provides new information for the research of eco-environment and life evolution of Jehol Biota in the area,as well as the geographical evolution and geological history of the Jehol Biota in North China.
