摘要:记述了产自浙江省天台盆地的网形蛋类新材料,建立一新蛋属——拟网形蛋属(Paradictyoolithus oogen. nov.), 两个新蛋种:庒前拟网形蛋(Paradictyoolithus zhuangqianensis oogen. et oosp. nov.)和下西山拟网形蛋(P. xiaxishanensis oogen. et oosp. nov.)。在此基础上,重新系统描述其他已知4种网形蛋属成员的结构特征,并对网形蛋类的分类进行了订正:网形蛋属(Dictyoolithus)仅保留红坡网形蛋(D. hongpoensis Zhao, 1994)一个蛋种;建立一新蛋属:原网形蛋属(Protodictyoolithus oogen. nov.), 将发现于河南西峡盆地的内乡网形蛋(D. neixiangensis Zhao, 1994)和发现于山东莱阳盆地的蒋氏网形蛋(D. jiangi Liu & Zhao, 2004)分别修订为:内乡原网形蛋(修订种)(Protodictyoolithus neixiangensis (Zhao, 1994) comb. nov.)和蒋氏原网形蛋(修订种)(P. jiangi (Liu & Zhao, 2004) comb. nov.); 此外,发现于吉林公主岭早白垩世的公主岭网形蛋(D. gongzhulingensis Wang et al., 2006)并不属于网形蛋类,而应归入似蜂窝蛋类(Similifaveoolithus), 将其修订为公主岭似蜂窝蛋(修订种)(Similifaveoolithus gongzhulingensis (Wang et al. 2006) comb. nov.)。

Abstract  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. gongzhulinensis, 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 that only D. hongpoensis belong to the Dictyoolithus, the other three species of Dictyoolithus should be reassigned to Protodictyoolithus neixiangensis comb. nov., P. jiangi comb. nov. and Similifaveoolithus gongzhulingensis comb. nov., respectively.

Key words  Tiantai Basin, Zhejiang Province, China; Late Cretaceous; dinosaur eggs, dictyoolithids
