Eomamenchisaurus was an early long-necked dinosaur that lived in what is now China. It was a sauropod, a giant plant-eater that walked on four legs and had a very long neck.1

izinto ezimnandi

Iinyani ezimnandi

1

Eomamenchisaurus means 'dawn Mamenchisaurus' because it is an early relative of the better-known Mamenchisaurus.1

2

Its thigh bone (femur) is 1.1 metres (3.6 feet) long, similar to the femur of Mamenchisaurus youngi, which was about 16 metres (52 feet) long.1

3

The tibia (shin bone) is only about 64% as long as the femur, a primitive feature compared to later sauropods.1

4

Some of its back vertebrae are fused together, a trait shared with other mamenchisaurid dinosaurs.1

5

The fourth trochanter (a ridge for muscle attachment on the femur) is on the inner side of the bone, like in early sauropods, not in the middle like in Mamenchisaurus.1

6

Eomamenchisaurus lived during the Middle Jurassic, about 174 to 161 million years ago.2

Yenziwe yi-AIUmfanekiso owenziwe yi-AI: Eomamenchisaurus
Umfanekiso owenziwe yi-AI obonisa indlela Eomamenchisaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Ukufunyanwa
Eomamenchisaurus was named in 2008 by Lü Junchang and colleagues based on a partial skeleton found in Jiangyi Township, Yuanmou County, Yunnan, China.1
Kusaxoxwa ngayo
Scientists are not sure if Eomamenchisaurus is actually different from another mamenchisaurid called Yuanmousaurus, which was found in the same rock formation.1
