Tarbosaurus, or Tyrannosaurus bataar, was a predatory dinosaur from Asia, similar to Tyrannosaurus rex, but slightly smaller. Their eggs were characterized by elongated shape, the scientific name of which is Macroelongatoolithus. However, according to recent research, similar eggs were laid by Oviraptosaurs, which also occurred in this area, so it is possible that the fossil can be linked to them.
