Mamenchisaurus

Translingual thumb Etymology From mul cmn - 馬門溪 Mǎménqī horse-gate brook, mul cmn-wadegiles - romanization: Ma³-mên²-chʻi¹ + mul -saurus. It was intended to name the reptile after the place where its fossil was first found — a construction site next to Mamingxi (馬鳴溪 Mǎmíngxī horse-neighing brook) Ferry Crossing by the Jinsha River (the westernmost major headwater stream of the Yangtze River), near Yibin in Sichuan Province of China. However, due to a mix-up by Young, the location name Mamingxi was mistaken as Mamenxi. Proper noun 1 m genus family Mamenchisauridae a large herbivorous sauropod dinosaur, with an exceptionally long neck, which lived during the Jurassic period en May 30, 2011 Big dinosaur exhibit at natural history museum w:The Washington Post https://web.archive.org/web/20231129013723/https://www.washingtonpost.com/lifestyle/style/big-dinosaur-exhibit-at-natural-history-museum/2011/04/14/AGGyXzEH_story.html 29 November 2023 https://www.washingtonpost.com/lifestyle/style/big-dinosaur-exhibit-at-natural-history-museum/2011/04/14/AGGyXzEH_story.html 0190-8286 2269358 Style The biggest star of the exhibit is a detailed model of a 60-foot-long Mamenchisaurus (pronounced mah-MUN-key-sore-us). “It’s a very long-necked animal from China,” said Mark Norell of the museum’s paleontology department. Its neck was 30 feet long! en 26 April 2014 Gobi desert reveals modest ancestor of gigantic flying reptiles w:South China Morning Post https://web.archive.org/web/20140426151408/https://www.scmp.com/news/china/article/1497294/gobi-desert-reveals-modest-ancestor-gigantic-flying-reptiles 26 April 2014 https://www.scmp.com/news/china/article/1497294/gobi-desert-reveals-modest-ancestor-gigantic-flying-reptiles 1563-9371 648902513 World Another important element of the discovery is the environment where Kryptodrakon lived. This was a river-dominated ecosystem far from the ocean in a region teeming with life, including a fearsome dinosaur predator called Sinraptor and a gigantic plant-eating dinosaur named Mamenchisaurus that boasted one of the longest necks of any creature yet to walk the planet. en March 15, 2023 Jack Tamisiea It’s Not a Stretch: This Dinosaur Had a 50-Foot Neck w:The New York Times https://web.archive.org/web/20230315130756/https://www.nytimes.com/2023/03/15/science/dinosaur-neck-mamenchisaurus-china.html 15 March 2023 https://www.nytimes.com/2023/03/15/science/dinosaur-neck-mamenchisaurus-china.html 0362-4331 1645522 Science To determine how Mamenchisaurus managed a neck as long as a semi-truck trailer, Dr. Moore and colleagues used a CT scanner to analyze the animal’s vertebrae. Instead of being stuffed with heavy marrow and tissue while the dinosaur was living, the interior of the sauropod’s vertebrae were filled with large air pockets similar to those found in modern birds like storks and swans. These empty pockets accounted for up to 77 percent of each bone’s volume, vastly decreasing the weight of Mamenchisaurus’s spine. en March 17, 2023 Will Sullivan This Dinosaur Had a 50-Foot-Long Neck, Scientists Say w:Smithsonian Magazine https://web.archive.org/web/20230320132926/https://www.smithsonianmag.com/smart-news/this-dinosaur-had-a-50-foot-long-neck-scientists-say-180981818/ 20 March 2023 https://www.smithsonianmag.com/smart-news/this-dinosaur-had-a-50-foot-long-neck-scientists-say-180981818/ The dinosaurs evolved a few ways to manage their unwieldy necks. Researchers used CT scans to find that most of the vertebrae’s volume—about 69 to 77 percent—was air, similar to the vertebrae of some birds. Such air-filled bones would be lighter, making it easier for the Mamenchisaurus to hold up its giant neck, per the statement. en Hypernyms genus Reptilia class - class; Saurischia order - order; †Sauropodomorpha suborder, †Sauropoda infraorder - clades References 1 1 1 mul Dinosaurs
