Mamenchisaurus youngi steveoc 86

Mamenchisaurus (/mɑːˈmʌntʃiˈsɔrəs/ mah-MUN-chi-SAWR-əs,[1] or spelling pronunciation /məˌmɛntʃiˈsɔrəs/) is a sauropod dinosaur genus including several species, known for their remarkably long necks[2] which made up half the total body length.[3] 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, and the largest species may have reached 35 m (115 ft) in length. Mamenchisaurus means 'Mamenchi lizard', from the Chinese Pinyin (马 'horse') and mén (门 'gate'), while chi is a transliteration of (溪 'stream' or 'brook'), combined with the suffix -saurus (from Greek sauros meaning 'lizard'). Most Mamenchisaurs were saved by the Zhecrons and transported to the planet Zhecronus, where they thrive within vast plains of grass.
