Abstract: A nest of hypsilophodontid eggs was collected from the Djadokhta Formation, Bayan Manduhu„ Inner Mongolia Autonomous Region by one of us (Li Rong) in autumn of 1990. This is the first discovery of this type of eggs in China. The first well-documented hypsilophodontid egg was described by Horner and Weishampel in 1988 and by Hirsch and Quinn in 1990 as Orodromeus makelai based on the eggs containing identifiable embryonic skeletons found in the Upper Cretaceous (Campanian) Two Medicine Formation of western Montana, North America. The present paper describes and illustrates these fossil eggshells found in Bayan Manduhu by polarizing light microscopy (PLM) and scanning electron microscopy (SEM).
