中国白垩纪蜂窝蛋化石的分类订正

A PARATAXONOMIC REVISION OF THE CRETACEOUS FAVEOLOOLITHID EGGS OF CHINA

重新系统描述了蜂窝蛋科蜂窝蛋属的模式蛋种宁夏蜂窝蛋(Faveoloolithus ningxiaensis)和杨氏蛋属的模式蛋种夏馆杨氏蛋(Youngoolithus xiaguanensis),并记述了产自浙江天台的蜂窝蛋科新材料,建立一个新的蛋属———副蜂窝蛋属(Parafaveoloolithus),及3个新的蛋种———Parafaveoloolithus microporus,P.macroporus和P.tiansicunensis。根据赵资奎1994年提出的恐龙蛋分类中具有鉴定意义的几个特征,重新讨论了现有蜂窝蛋的分类地位,提出杨氏蛋属应当提升为科一级的分类单元,总结了蜂窝蛋科内属级和种级分类单元的主要鉴定特征以及蜂窝蛋类的鉴定方法。

The Faveoloolithidae,erected by Zhao and Ding （1976）,were first described from the Albian-Cenomanian of the Gobi Desert,Mongolia （Sochava,1969,1971）,and were assigned the name multicanaliculate. The group includes Faveoloolithus ningxiaensis Zhao Ding,1976 from the Cretaceous of Alxa,Nei Mongol and Youngoolithus xiaguanensis Zhao,1979 from the Cretaceous of Xiaguan Basin,Henan Province. So far,faveoloolithid eggs have been reported from Xichuan,Xixia （Zhou and Han,1993; Zhang and Li,1998） and Wulichuan basins （Zhou and Feng,2002） in Henan Province,Jinqu,Tiantai （Zhang and Li,1998） and Yongkang basins （Yu et al.,2003） in Zhejiang Province,and Qinglong Mountain in Hubei Province （Guan et al.,1997; Zhou et al.,1998）. Clutches have also been found in Khermiyn-Tsav and Ikh-Shunkht in Mongolia （Mikhailov et al.,1994）,and Bosung in South Korea （Huh and Zelenitsky,2002）. However,except for F . ningxiaensis and Y . xiaguanensis ,other specimens’ parataxonomic position within Faveoloolithidae was uncertain. In this paper,detailed redescriptions of the holotypes of F . ningxiaensis and Y . xiaguanensis ,and of some new material from Tiantai Basin,Zhejiang Province,are presented along with comments on the parataxonomy of this group of eggs.
