The eggs were preserved standing up, vertically and obliquely in siltstone. Eggshells are very thin and smooth on the outer surface. The thickness of the eggshell is between 0.6 and 0.9 mm. The eggs are 105– 116 mm long and 36–48 mm wide. Possibly Prismatoolithus gebiensis Zhao & Li, 1993. Prismatoolithus eggs likely belonged to troodontids.
