Liang Long lived in the western part of North America at the end of Jurassic, from1500,000 years ago to1470,000 years ago. The longest individual can exceed 30 meters and weigh about 10 ton. Noses are above the eyes. Their necks can't be lifted, and they should be used to expand the eating area in situ.

Liang Long's body is very thin, weighing only a dozen tons, because its back bone is very light, much smaller than Puzzled Dragon and Brachiosaurus.

Its teeth only grow in the front of its mouth, which is very small, so it can only eat soft and juicy plants. The long whiplike tail can help it resist the enemy and drive away other small animals wherever it goes.

Extended data:

1878, samuel wendell williston, an American paleontologist, discovered the first fossil of Liang Long in Como Cliff, Wyoming. In the same year, the paleontologist othniel charles marsh named it D. Liang Long.

Later, Liang Long's fossils were found in Morrison formation in Colorado, Utah, Montana and Wyoming in the western United States. Fossils are common in Liang Long. Although relatively complete bones have been found, skulls are rarely found.

Although D. Liang Long is not a model species, he has found the most complete skeleton. His skeleton models are exhibited in many museums all over the world, and they are the most widely known.
