摘要：The dinosaurian eggs described in this paper were collected from the Red-Beds in western Dongting Basin, Hunan. The following is a list of the fossil eggs in the present article:
Phacelaolithus humanensis gen. et sp. nov.
Elongatoolithus magnus sp. nov.
The Phaceloolithus hunanensis gen. et sp.nov. may represent a new family Phaceloolithidae. Its diagenosis may be listed as follows:
1. The outer view is nearly subspherical. Their long and equatorial diameters are 167-168 mm and 140-150 mm respectively.
2. The eggshell is rather thin, between 0.5-0.7 mm in thickness. The structure of the eggshell is composed of mammillary layer and stratified prismatic one. Mammillae are, in general, compressed by twos and threes in a single stratum. The pore canals in stratified prismatic layer are well-developed.
Based on assemblages of the fossil eggs and its associated fossil (Ostracoda, Charophyta) the age of fossil eggs bearing beds is estimated as late age to late Cretaceous.
