Futalognkosaurus dukei
Futalognkosaurus is a genus of titanosaurian dinosaur. The herbivorous Futalognkosaurus lived approximately 87 million years ago in the Portezuelo Formation, in what is now Argentina, of the Coniacian stage of the late Cretaceous Period. The fish and fossilized leaf debris on the site, together with other dinosaur remains, suggest a warm tropical climate in Patagonia during this period. Gregory S. Paul found that Futalognkosaurus had an average length of 30 metres (98 ft) and a weight of 50 tons. Its long neck contained 14 vertebrae, and was over a meter deep in places, due to its extremely tall neural spines which had a distinctive "shark-fin" shape. The hips were also extremely large and bulky, reaching a width of nearly 3 metres (9.8 ft). The alternate early spelling "Futalongkosaurus" may be found in some press reports and on websites.
Mamenchisaurus sinocanadorum
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).
