Abstract: In 1987, a team from the Kunming Muniipal Museum found and excavated a nearly complete specimen of a new species of theropod, Dilophosaurus sinensis, from Xiyang Village, Jinning County, Yunnan Province. The sp cimen was associated with a skeleton of Yunnanosaurus in the Lower Jurassic sediments of the Lower Lufeng Formation. The discovery of Dilophosaurus in China suggests there were close connections between North America and Asia during the Early Jurassic.
