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). [1] While no remains of Heishanoolithus have been associated with skeletal remains, strong evidence links Elongatoolithid eggs to Oviraptorosaurs. [2]
