Stromatoolithus is an oogenus of dinosaur egg known from the Late Cretaceous of what is now Asia, Europe, and North America. They were likely laid by hadrosauroid dinosaurs. The type oospecies is S. pinglingensis. Other species include S. porcarboris (formerly thought to be a oospecies of Paraspheroolithus), S. albertensis, and S. europaeus (both formerly thought to be oospecies of Spheroolithus).
