| Abstract: | Diverse dinosaur tracks (Theropoda, Ornithopoda and Sauropoda) were discovered from the Early Cretaceous, Laiyang Group, Longwangzhuang Formation in the Huanghuazhen Area, Zhucheng City, Shandong Province. Dinosaur track fossils were preserved in yellow green, gray green shore—shallow lacustrine and fluvial sediments of argillaceous siltstone and fine-grained sandstone. The deep elliptic footprints of sauropoda dinosaurs show they weigh much, walk on manus and pes of the similar size. Both ornithopod and theropod walk on two feet. The footprints show their feet are three-toed. Theropoda have the lightest weight and the largest number among the three kinds of dinosaurs. Most dinosaurs were taking a walk or in a trot from east to west. Part of dinosaur footprints show the motion states of turning, slowing down and stopping. From the strong regularity of dinosaur trackways, we deduce the dinosaurs may be in collective migration. Based on footprints’ characteristics and conservation situation, the deformation degree of dinosaur footprints in this area were divided into four kinds of degree (un-deformation, weak-deformation, medium-deformation, strong-deformation). Furthermore, in order to provide more accurate information for species, sizes, behaviors, kinematic features of dinosaurs and lithology, palaeoenvironment, palaeoecology of strata, simple methods of dinosaur footprints reconstruction were put forward and discussed in this paper. |
