Mamenchisaurus hochuanensis
Mamenchisaurus ( /mɑːˈmʌntʃiˈsɔrəs/ mah-MUN-chi-SAWR-əs, or spelling pronunciation /məˌmɛntʃiˈsɔrəs/) was a plant-eating four-legged dinosaur, known for its remarkably long neck, which made up half its total length. It is known from numerous species which ranged in time from 160 to 145 million years ago, from the Oxfordian to Tithonian ages of the late Jurassic Period of China. Mamenchisaurus means 'Mamenchi lizard', from the Chinese Pinyin mǎ (马 'horse') and mén (门 'gate'), while chi is a transliteration of xī (溪 'stream' or 'brook'), combined with the suffix -saurus (from Greek sauros meaning 'lizard'). Mamenchisaurus was first discovered in 1952 on the construction site of the Yitang Highway in Sichuan, China. The partial skeleton fossil was then studied, and named Mamenchisaurus constructus in 1954, by the renowned Chinese paleontologist Professor C. C. Young. The type specimen had an incomplete neck with 14 vertebra preserved and none of these were complete . M. constructus was estimated at 13 m (43 ft) long. In 1972, a second species of Mamenchisaurus was discovered (M. hochuanensis) with a neck that reached up to 9.3 m (31 ft) in length. This species had a complete neck preserved which contained 19 vertebrae. In 1994, Sauroposeidon was discovered in the United States, with a neck estimated to be between 10.5 and 11.5 meters (34.5–37.5 feet) long, though its neck did not exceed that of the previously known Supersaurus, with a neck reaching 13–14 meters (42.5–46 feet).
NOTE: We are using the 22 meter, 18 tonne Mamenchisaurus hochuanensis for this matchup
Tarbosaurus bataar
Tarbosaurus belongs in the subfamily Tyrannosaurinae within the family Tyrannosauridae, along with the earlier Daspletosaurus, the more recent Tyrannosaurus and possibly Alioramus. Animals in this subfamily are more closely related to Tyrannosaurus than to Albertosaurus and are known for their robust build with proportionally larger skulls and longer femurs than in the other subfamily, the Albertosaurinae. Although many specimens of this genus have been found, little definite data was confirmed on the dinosaur as of 1986, though it was presumed to share many characteristics with other tyrannosaurids. The close similarities have prompted some scientists to suggest a possible link between the North American and Eurasian continents at that time, perhaps in the form of a land bridge.As with most dinosaurs, Tarbosaurus size estimates have varied through recent years. It could have been 10 to 12 meters long, with a weight of 5 - 7 tons.

NOTE: I know this thread may seem superfluous given the Mamenchisaurus vs T rex thread, but T rex and Tarbosaurus are generally viewed as distinct enough to match against the same animals, and this is at a slightly different size ratio, so it may have a different result
