He meant to name the dinosaur’s genus after the river where it was found, but mistakenly identified it as Mǎménxī (meaning “horse-gate brook”) instead of Mǎmíngxī (meaning “neighing horse brook”). He recognized at the time that this animal would have been 13 to 15 meters (43 to 49 feet) in length it was named Mamenchisaurus constructus, due to the fact that it was found at a construction site. Despite the fossil being incomplete (and the neck incomplete as well), it was studied by paleontologist Professor Yang Zhongjian (more widely known as C. The first fossils of Mamenchisaurus were discovered in 1952 during the construction of the Yitang Highway in Sichuan, China. This is one of the largest dinosaurs known, reaching lengths in excess of one hundred feet. Its name was intended to mean “Mamenchi Ferry reptile” in reference to the location where it was discovered in China this is actually a misspelling, as it should be “Mamingchi” rather than “Mamenchi.” Despite this error, the rules of taxonomy mandate that the name remains as it is. Mamenchisaurus is a very large sauropod dinosaur in the family Mamenchisauridae which lived in the Late Jurassic during the Oxfordian to Tithonian ages, around 160 to 145 million years ago. ![]()
