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

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.
