''Mamenchisaurus'' (pronounced ''ma-MENCH-ih-SAW-rus'') was first discovered in China by C. C. Young. It is a Plant-eating Four-legged Dinosaur , known for its astonishingly long Neck .

The first specimen discovered (the Type Specimen ) was 22 Meter s (72 Feet ) long, and half of that was neck (11 meters, or 36 feet) — which made it the longest known neck any animal at the time. 19 Vertebra e were discovered (another record), along with long rods that were found in the neck. It is thought that adults could average up to 82 ft. long.

In 1987, a different species of ''Mamenchisaurus'' was discovered (''M. hochuanensis'') with a neck that might have reached up to 15 meters (49 feet) in length. In 1994, the '' Sauroposeidon '' was discovered in the United States , with a neck estimated to be up to 12 meters (39 feet) long; though since the ''Sauroposeidon'' is a Brachiosaurid , with very long forelimbs, it is a much taller dinosaur.

''Mamenchisaurus'' means "Mamenchi lizard", from the Chinese ''ma'' ("horse"), ''men'' ("gate") and ''chi'' ("stream"), and the Greek ''sauros'' ("lizard"). It was named for the Mamingxi Ferry in Jinshajiang , on the Yangtze River , Yibin , in the Sichuan Province of China , where it was found.

Most species lived 145 to 150 Million Years Ago , in the Tithonian Age of the late Jurassic Period .

A herd of mamenchisaurs were featured in the roundup scene in .
