Here we describe an incomplete dinosaur clutch with three broken eggs and seven prints discovered in Wuning County, Jiangxi Province, that can be referred to Coralloidoolithus shizuiwanensis based on the following features: the eggs are nearly spheroid and arranged tightly and irregularly in the clutch, the eggshell thickness ranges 2.76-2.97 mm, the horizontal accretion lines are almost evenly distributed throughout the eggshell, and the secondary eggshell units are distributed in the medial and outer zones of the columnar layer. This egg clutch of Coralloidoolithus shizuiwanensis represents the first discovery of dinosaur eggs in Wuning County, and shows the age of the strata containing the dinosaur eggs in this area should be Late Cretaceous.
