浙江省义乌市发现了一种新类型的恐龙蛋化石,外表面上具有大致相互平行的波状分枝裂隙。这种奇特的纹饰表明这种蛋不属于已知的任何蛋科。有趣的是,它们与曾经被归于树枝蛋科的南马东阳蛋(Dongyangoolithus nanmaensis)有一些相同的蛋壳显微特征：外表面的分枝裂隙和被巨大空腔分隔的壳单元集合体。考虑到地点和层位都很接近,这一新类型的恐龙蛋和南马东阳蛋应被归于一新蛋科。由于这种新类型恐龙蛋的壳单元集合体及裂隙的形态不同于南马东阳蛋,因此又建立了一个新的蛋属、蛋种——赤岸多裂隙蛋(Multifissoolithus chianensis)。新蛋科与圆形蛋科的圆形蛋属(Spheroolithus)有较近的亲缘关系,还具有一种过渡型的气体交换系统。

A new type of dinosaur egg, which is remarkable for the roughly paralleled, wavy and branched clefts on the outer surface, was recovered from Yiwu, Zhejiang Province, China. The extraordinary ornamentation indicates that the eggs do not belong to any known oofamilies. Interestingly, they share the following eggshell micro-features with Dongyangoolithus nanmaensis, which was previously assigned to the Dendroolithidae: branched clefts on the outer surface of the eggshell and eggshell unit assemblages separated by large cavities. Due to these similarities and the nearness of their localities and similar horizons, the new type of dinosaur eggs from Yiwu and D. nanmaensis likely represents a new oofamily, Dongyangoolithidae. Based on the differences in shape between the eggshell unit assemblages and clefts of the new type of dinosaur eggs and D. nanmaensis, we erect a new oogenus and a new oospecies, Multifissoolithus chianensis. The new oofamily reported here shows a close relationship with Spheroolithus in Spheroolithidae and an intermediate pattern of gas exchange systems.
