Keichousaurus was a small marine reptile that swam in warm seas during the Triassic Period. It had a long neck, a long tail, and paddle-like limbs to row through the water.1

izinto ezimnandi

Iinyani ezimnandi

1

Keichousaurus gave birth to live young instead of laying eggs. Baby fossils have been found inside adult females.1

2

This reptile had very broad ulna bones in its forelimbs, which helped make its paddles more effective for swimming.1

3

Males grew slightly larger than females. Mature males reached about 16 cm snout-vent length, while females reached about 15 cm.1

4

Keichousaurus is one of the most common sauropterygian fossils found in China. Many complete skeletons have been collected.1

5

It had a long, serpentine neck and a small head, similar to other pachypleurosaurs.1

6

Keichousaurus probably used a rowing motion with its paddle-like limbs to move through the water.1

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

Ukufunyanwa
The first fossil of Keichousaurus was found in 1957 in Guizhou Province, China, by Hu Chengzhi. It was named by Chinese paleontologist Young Chung-chien in 1958.1
Kusaxoxwa ngayo
Scientists are not sure whether Keichousaurus was viviparous (giving birth to live young) or ovoviviparous (eggs hatching inside the mother).3
