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

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

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

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

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

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