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
