摘　　要：记述了江西省武宁县发现的一恐龙蛋不完整蛋窝。基于以下特征将这一新发现归入石嘴湾珊瑚蛋(Coralloidoolithus shizuiwanensis):恐龙蛋化石近球形,在蛋窝中紧密不规则分布,蛋壳厚度2.76-2.97 mm;水平生长线均匀分布于整个蛋壳,柱状层中段和外段发育大量次生壳单元。这一蛋窝代表了武宁县恐龙蛋化石的首次发现,也说明该区域产恐龙蛋地层时代应该为晚白垩世。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.
