Genuine Fossilized Keichousaurus in Matrix (801.2 grams)

Description

This is a fine example of a semiaquatic reptile from the Triasssic of China known as Keichousaurus hui. The Keichosaurs were members of the Pachypleurisauridae, and as such were related to their contemporaries the Nothosaurs (indeed, at one point they were referred to the Nothosauridae). They are thought to have been a bridge between the Placodonts and the later Plesiosaurs. The Keichousaurs were thought to be able to make their way on land by virtue of their strong limbs (note the robust ulna).Name: Keichousaurus huiAge: Early Triassic, Spathian Stage (~242 m.y.a.)Location: Huxia Formation, Guanglin, Guizhou Province of ChinaWeight: 801.2 grams, Size: 8 x .5 x 4 inches
