Tarbosaurus


There has been a change of heart due to more study. Tarbosaurus has been resurrected from the grave, so to speak. It now seems that there are characters that make Daspletosaurus a more likely ancestor of Tyrannosaurus than is Tarbosaurus. This means the Asian tyrannosaurid has been returned to full generic status. These studies have also shown that there is a strong possibility that Shanshanosaurus is a juvenile Tarbosaurus, sinking that genus. What a rethink!

There is a possibility that T. bataar can be split further into T. bataar and T. efremovi.

I am also including Maleevosaurus novijilovi under T. bataar. This is against Carpenter (1992) and I am doing so based on Carr (1998).


  • T. bataar
    • 10-12 m (35-40 feet) long, 4.5-5 tonnes (5-5.5 tons)
    • Late Cretaceous (Maastrichtian)
    • over a dozen decent skeletons found, know from fairly complete skeletons
    • found in the Gobi of China and Mongolia
    • Named By: Maleev, E.A. (1955) ["Gigantic carnivorous dinosaurs of Mongolia"]. Doklady Akademii Nauk S.S.S.R. 104: 634-637. (In Russian)
