摘要: 浙江天台盆地上白垩统赤城山组发现一新的恐龙蛋类型。依据蛋化石形态、大小和蛋壳柱状层生长纹呈波浪形等特征,将其归入长形蛋科(Elongatoolithidae)。这枚恐龙蛋的蛋壳外表面具网状纹饰,蛋壳锥体层与柱状层界线明显,二者厚度之比近1:2,气孔道细而直,这些特征区别于其他长形蛋科的成员,因此,建立一新的蛋属、蛋种:网纹副长形蛋(Paraelongatoolithus reticulatus oogen. et oosp. nov.), 代表晚白垩世早期长形蛋科的新成员。

Abstract: Dinosaur eggs are abundant in Tiantai, Zhejiang Province, southeastern China. Some egg taxa have been reported, but most of them were not properly erected. Here, we describe a new egg specimen from the Upper Cretaceous Chichengshan Formation of the Tiantai Basin.
