中文摘要：

依据采自江西省萍乡地区上白垩统周田组的恐龙蛋化石，记述了蜂窝蛋科（Faveoloolithidae）副蜂窝蛋属（Parafaveoloolithus）一新蛋种：材料包括一枚较完整的蛋和若干破碎蛋壳。根据蛋壳弦切面呈蜂窝状结构，径切面蛋壳中、上部蛋壳局部呈现由6～10个以上壳单元成群聚集一起等特征，将其订为一新蛋种——萍乡副蜂窝蛋（Parafaveoloolithuspingxiangensisoosp．nov．）：

英文摘要：

Upper Cretaceous dinosaur egg clutches, single eggs, and countless eggshell fragments have been found in the Pingxiang Basin, Jiangxi Province since 2002. In this paper, the specimens described from the Pingxiang Basin are oblate in shape. The polar axis of this egg is 7.32 cm, the equatorial diameter is 13.81 cm, and its shape index is 189. Outer surface is smooth. Eggshell is usually composed of three or five superimposed slender shell units. In some portions, 6-10 shell units are assembled in the middle and upper part of the eggshell. Pores are straight and unbranching, extremely numerous, and closely spaced, looking as a whole like a honeycomb in tangential section through the middle part of the eggshell. Compared to the members of faveoloolithids, the specimens described here should be ascribed to the oogenus Parafaveoloolithus on the basis of some shell units tending to assemble in the middle and upper part of the eggshell. However, the difference is remarkable between the new specimen and the known oospecies, Parafaveoloolithus microporus, P. macroporus, P. tiansicunensis and P. guoqingsiensis, of which the eggshell has usually two or three shell units tending to assemble in the middle part of the eggshell. Therefore, the specimens described here represent a new oospecies, Parafaveoloolithus pingxiangensis oosp. nov.
