| 摘 要： | Dinosaur eggshells from the Cretaceous red beds of southern China were selected for element geochemical study.The concentrations of the major elements indicate that the eggshells did not change much in their chemical composition after they were formed.Variations in the contents of trace elements and REEs imply that a palaeoclimatic anomaly might occur during Late Cretaceous.

| Abstract: | Dinosaur eggshells from the Cretaceous red beds of southern China were selected for element geochemical study. The concentrations
of the major elements indicates that the eggshells did not change much in their chemical composition after they were formed.
Variations in the contents of trace elements and REEs imply that a palaeoclimatic anomaly might occur during Late Cretaceous.
