Abstract: In 1983, Dong & Tang (1983) described material of two partial skeletons of an ornithopod collected from the dinosaurian bone quarry at Dashanpu, Zigong, Sichuan Province and coined the name Xiaosaurus dashazpensis. After that, He & Cai (1983, 1984) described two well-preserved skeletons of another ornithopod and denominated them as Yandusaurus multidens. In 1984 in the course of digging the foundation of the building of the Zigong Dinosaur Museum, a nearly complete skeleton of a small ornithopod was collected. It was briefly (lescribed by Peng (1990) and named as Agilisaurus louderbacki. Because this skeleton is So far among the most complete one known in China, or even in the world, it is significant in studying the evolution, paleobiogeography and functional morphology of the ornithopods, so a detailed study of it has been carried out.

摘要： 本文对四川自贡大山铺的劳氏灵龙(Agilisaurus louderbacki)材料作了系统描述，并讨论了它的系统位置及与其它相关属种的关系。经比较:Yandusaurus multidens:应转归灵龙属中，成为灵龙的另一个种—多齿灵龙(Agilisaurus multidens); Xiaosaurus dashanpensis可作为独立的属种。
