Gobioolithidae
''Gobioolithus'' is an oogenus of fossil bird egg native to Mongolia. They are small, smooth-shelled, and elongated eggs that were first discovered in the 1960s and early 70s during a series of fossil-hunting expeditions in the Gobi desert. Two oospecies have been described: ''Gobioolithus minor'' and ''G. major''. The eggs were probably laid in colonial nesting sites on the banks of rivers and lakes. ''G. minor'' is unusual because it frequently is found with embryonic skeletons of the enantiornithine bird ''Gobipipus''. These embryos have well-developed wings, which suggest they would be able to fly very soon after hatching, unlike most modern birds. Description ''Gobioolithus'' eggs are small and smooth-shelled. They are asymmetrically shaped, similar to many modern bird eggs, with one end pointier than the other. The two oospecies are distinguished mainly by their size: ''G. major'' ranges from 50 to 53.5 mm long and 25 to 32 mm across, with an eggshell thickness ...
