- Lived within the Jurassic in what’s now China
- A number of species, largest one about 115 ft (35 m) lengthy and weighing 50-75 tons
- Sort species is Mamenchisaurus constructus
- Mamenchisaurus constructus was round 43-49 ft (13-15 m) lengthy
- Found in 1952 on a building web site in Sichuan, China
- Discovered a partial skeleton, named in 1954 by C.C. Younger

- Imagined to be named after the place it was discovered, which was a building web site subsequent to the Mamingxi ferry crossing, within the Sichuan province in China. However Younger by accident blended up the situation title and Mamingxi (which implies horse neighing brook) was mistaken as Mamenxi (horse gate brook)
- Species named as a result of the fossil was present in a building web site
- A guide referred to as The Chronicles of Huayang, written within the Jin Dynasty between 265-317 CE, describes the discovering of “dragon bones” in what’s now the Sichuan Province (numerous Jurassic fossils, together with Mamenchisaurus bones, have been discovered there), so they could have contributed to folklore about dragons
- Individuals used to consider dragon bones had medicinal qualities
- Second species, Mamenchisaurus hochuanensis, was described in 1972. About 72 ft (22 m) lengthy, and its neck was 31 ft (9.3 m) lengthy. Had a whole neck preserved with 19 vertebrae
- One other Mamenchisaurus hochuanensis specimen present in 2001, and it had a membership tail, most likely used for protection (different sauropods with membership tails have been Omeisaurus and Shunosaurus
- One other species, Mamenchisaurus sinocanadorum was described in 1993 (discovered cranium materials and first 4 cervical vertebrae). Had the longest cervical rib of any described sauropod, at 13.5 ft (4.1 m) lengthy (longest species typically, estimated at 115 ft or 35 m lengthy with a neck that’s 56 ft (17 m) lengthy)
- Mamenchisaurus anyuensis was named in 1996, and was about 69 ft (21 m ) lengthy
- Mamenchisaurus jingyanensis was named in 1998 and was about 66-85 ft (20-26 m) lengthy
- Mamenchisaurus youngi was named in 1996 (although initially present in 1989), and is called in honor of Younger. It was 52 ft (16 m) lengthy with a 21 ft (6.5 m) lengthy neck
- Mamenchisaurus youngi‘s vertebrae above its hips have been fused collectively in a v-shape, so it could have needed to maintain its tail up at a 20 diploma angle
- One examine from 2013 discovered that Mamenchisaurus youngi could have eaten low vegetation, based mostly on the stiffness of its vertebrae (had a fairly straight neck posture and was a low browser)
- One Mamenchisaurus discovered had an injured tail, most likely because of a damaged and re-healed spine damage or an infection that brought about ossified tissue to construct up
- Lengthy neck means it might eat lots of meals from the identical spot (due to its attain)
- Had spatula formed tooth, which have been good for consuming giant bunches of leaves
- Can see an animatronic Mamenchisaurus in Prague, on the Harfa DinoPark

- Named in 1972 by Younger and Zhao, in a paper about Mamenchisaurus
- Consists of Chuanjiesaurus, Eomamenchisaurus, Hudiesaurus, Tienshanosaurus, Omeisaurus, Tonganosaurus
- Enjoyable truth: Impressed by a reddit put up by JimmyL2014: It’s utterly possible that there have been Mesozoic dinosaurs (non-avian even) that would scoot round a lake like a duck.
- Many dinosaurs would have been good and buoyant given their pneumaticity
- Now we have some proof of dinosaurs swimming (i.e. stegosaur transitional prints)
- They may have used their giant tails and ft (presumably webbed) for locomotion
- Many items of proof that they ate fish
- A few of them had feathers (though not likely essential for floating).
