Wang, Q., ZhaO, Z.-K., WANG, X.-L., Zhang, S.-K. & Jiang, Y.-G. (2013) New forms of dictyoolithids from the Tiantai Basin, Zhejiang Province of China and a parataxonomic revision of the dictyoolithids. Vertebrata PalAsiatica 51 (1): 43-54
Dinosaur eggs collected from the Upper Cretaceous Chichengshan Formation in the Tiantai Basin of Zhejiang Province are referable to the oofamily Dictyoolithidae. On the basis of general external shape, size, eggshell thickness, and eggshell composed of 3-4 superimposed slender shell units with a reticulate organization, a new oogenus and two oospecies, Paradictyoolithus zhuangqianensis oogen. et oosp. nov., and P. xiaxishanensis oogen. et oosp. nov., are erected. The Dictyoolithidae is previously represented by one oogenus and four oospecies, Dictyoolithus hongpoensis, D. neixiangensis, D. jiangi, and D. gongzhulingensis, all of which are known exclusively from the Cretaceous of China. We re-examined the holotypes of the four oospecies, established a new oogenus Protodictyoolithus, and propose only D. hongpoensis belong to the Dictyoolithus, the other that three species of Dictyoolithus should be reassigned to Protodictyoolithus neixiangensis comb. nov., P. jiangi comb. nov. and Similifaveoolithus gongzhulingensis comb. nov., respectively.
