Triassic Period- C. 250-200 million years old

Order to which the fossil belongs: Nothosauroidea
Name of which the family belongs: Pachypleurosauria

This is nice example of a semiaquatic reptile from the late-Triassic period. The Keichousaurus Hui were specialised fish eaters and a member of the Pleurosaur family, which became extinct during the Triassic-Jurassic extinction event, around 250 millions years ago. It was in 1957 when the first fossil specimen was discovered from Kweichow (now Guizhou Province) in China, where the name Keichousaurus derives from. They were said to be highly unusual amongst marine reptiles due to the fact that they gave birth to live young instead of laying eggs.

Although repaired it is an excellent example with fine definition on a stone matrix.
