| Abstract: | After the report of dinosaur footprints in the Early Cretaceous in 2000 (Li et al., 2000), we followed to unearth, investigate and research the footprints with the support of National Natural Science Fundation and Stadholder Fund of Gansu Province. At present, there are ten track sites about 286 footprints within 2 km2 area in Yanguoxia, three of which are being unearthed. Among all the sites, the footprints are best preserved in Site 1, where 187 footprints are found and they are arranged into 17 trackways within about 600 m2 (Fig.1). In the site 2, 51 footprints in 17 trackways are found within the 80 m2. And 4 footprints in 2 trackways are preserved within 50 m2 of site 3. In other footprint sites, the number of footprints is different, ranging from 1 to 12. |
