Abstract: This paper briefly reviewed the history of the discovery and research of dinosaur eggs in Laiyang, Shandong Province, China. Combining with the new discoveries in the Laiyang basin in recent years, the composition of the Laiyang dinosaur egg fauna was revised from 4 oofamilies, 5 oogenera and 11 oospecies to 6 oofamilies and progress on the dinosaur eggs, 10 oogenera and 12 oospecies, 1 oofamily indet. and 1 doubtful oospecies. Compared assemblages with other dinosaur egg faunas in China, the Laiyang dinosaur egg fauna is a typical representative of the Late Cretaceous dinosaur egg fauna with diverse egg types and distinctive assemblage characteristics. At the same time, this combination also well reflects the high diversity of dinosaurs in the Wangshi Group of the Jiaolai basin during the Late Cretaceous. Further study on it will provide detailed paleontological evidence for further discussion on the paleogeography and paleoenvironment of Laiyang area in the Late Cretaceous.
