''Heishanoolithus'' is an oogenus of Elongatoolithid fossil egg from the Shahai Formation in Liaoning. It is known only from seven eggshell fragments. It is most notable for having a very thin eggshell (1.2-1.3 mm thick), the dense covering of nodes on the eggshell surface, and for its relatively thin mammilary layer (making up only one eighth of the eggshell thickness).〔Zhao H. and Zhao Z. (1999) "(A New Form of Elongatoolithid Dinosaur Eggs from the Lower Cretaceous Shahai Formation of Heishan, Liaoning Province )." ''Vertebrata PalAsiatica'', 37(4): 278-284.〕 While no remains of ''Heishanoolithus'' have been associated with skeletal remains, strong evidence links Elongatoolithid eggs to Oviraptorosaurs.〔Simon, D. J. (2014).
