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.
