| The First Discovery of Dinosaur Eggs in Laixi Area of Qingdao, Shandong Province, and Sedimentary Environmental Analysis |
| The first discovery of dinosaur eggs from the Late Cretaceous Hongtuya Formation of Laixi area of Qingdao in Shandong Province is reported in this paper. The shape of the egg is round with a diameter of 11 cm. According to the microstructure of the egg shell, they are assigned to the oofamily Dendroolithidae, probably belonging to therizinosauroid dinosaurs. The sedimentary environment and rock geochemistry analysis suggest that the study area was mainly dominated by the river channel and flood plain sedimentary environments, probably a favorable nesting site for dinosaurs under the optimum palaeoclimatic condition. At the meantime, the discovery of therizinosauroid eggs provides a possibility to find therizinosauroid skeletons from this area in the future. |
