概览
此内容目前仅提供英文版。
Tarbosaurus bataar lived in what is now the Gobi Desert of Mongolia in the Late Cretaceous, among rivers and floodplains of the Nemegt Formation. Soviet-Mongolian expeditions of 1946-1949 found several tyrannosaurid skeletons in the Nemegt Basin, and Evgeny Maleev named the first one Tyrannosaurus bataar in 1955 (holotype PIN 551-1).
Maleev named several species from these skeletons; in 1965 Anatoly Rozhdestvensky merged them all into Tarbosaurus bataar. It is one of the best-known tyrannosaurids, with dozens of specimens from juveniles to adults.
Hurum and Sabath (2003) compared its skull with that of Tyrannosaurus: it is narrower, especially at the snout, and has a locking joint between two bones of the lower jaw. They proposed that Asian and North American tyrannosaurines form separate branches. A juvenile skull described in 2011 suggests that young and adult Tarbosaurus hunted different prey.
名称含义
"Alarming lizard", from Greek tarbos ("terror, alarm") and sauros ("lizard"); bataar, from Mongolian baatar ("hero") (Maleev 1955).
生物学与证据
科学家对这种动物生活方式的看法,以及每种观点的证据有多充分。
生物力学
Tarbosaurus had a locking joint in its lower jaw that T. rex lacked.
证据等级:有力证据A ridge on one lower-jaw bone fits notches on the next, stiffening the jaw. It is linked to a different way of handling a crushing bite.

Bone-by-bone comparison: a narrower skull and snout, a domed nasal less attached to other bones, and a dentary-angular interlock in the lower jaw.
标本: PIN 551-1
其他
Asian and North American giant tyrannosaurs form separate branches.
证据等级:假说Hurum and Sabath proposed that Tarbosaurus groups with Alioramus in Asia, apart from Daspletosaurus and Tyrannosaurus. Other analyses place Tarbosaurus as the closest relative of T. rex.
