河南栾川晚白垩世秋扒组甲龙类化石的发现及意义

Discovery and significance of ankylosaur specimens from the Late Cretaceous Qiupa Formation in Luanchuan, Henan, China

摘要: 报道了河南省栾川县秋扒乡晚白垩世秋扒组发现的甲龙类化石。化石包括单枚牙齿、一几乎完整的背椎体、不完整的肋骨和坐骨。虽然化石材料少，难以确立属种，但是这是除中原龙产地外，中原地区发现的第二个甲龙类化石点。该化石的发现为研究甲龙类的迁徙及其古地理分布特点提供了重要信息。

Abstract: Ankylosaur specimens discovered from Late Cretaceous Qiupa Formation in Qiupa Town, Luanchuan County, Henan Province are reported. The ankylosaur specimens include a single tooth, a nearly complete dorsal vertebra, incomplete dorsal rib and ischium. Although the specimens are not enough to be established as a new taxon, this is the second ankylosaurid site except for the locality of Zhongyuanosaurus in central China. Its discovery provides important information on the migration and paleogeographic distribution of ankylosaurs.
