They were all labeled as Tarbosaurus bataar at the exhibition. Isn't it a
general problem in paleontology: distinguishing genuses and species from
different gender and growth stage?  There was also one rather small
interesting
theropod - tyrannosaurid ( dark - almost black stone) skull with relatively
large teeth placed among Tarbosaurus specimens. When I
asked Mongolian curator about it, she answered it was a young Tarbosaurus.
Its teeth however, were relatively bigger than the teeth of the bigger
specimens. The shape of the skull was also quite different.
